  16. Truck transport of RAM: Risk effects of avoiding metropolitan areas

    SciTech Connect

    Mills, G.S.; Neuhauser, K.S.

    1997-11-01

    In the transport of radioactive material (RAM), e.g., spent nuclear fuel (SNF), stakeholders are generally most concerned about risks in high population density areas along transportation routes because of the perceived high consequences of potential accidents. The most significant portions of a transcontinental route and an alternative examined previously were evaluated again using population density data derived from US Census Block data. This method of characterizing population that adjoins route segments offers improved resolution of population density variations, especially in high population density areas along typical transport routes. Calculated incident free doses and accident dose risks for these routes, and the rural, suburban and urban segments are presented for comparison of their relative magnitudes. The results indicate that modification of this route to avoid major metropolitan areas through use of non-Interstate highways increases total risk yet does not eliminate a relatively small urban component of the accident dose risk. This conclusion is not altered by improved resolution of route segments adjoining high density populations.

    The safety of magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is the responsibility of the Federal Railroad Administration (FRA). Plans for near future US applications include maglev technology (e.g. in Orlando, FL and Pittsburgh, PA) and high speed rail (e.g. the French Train a Grande Vitesse (TGV) in the Texas Triangle, between Dallas-Fort Worth, Houston and San Antonio, and along five designated high speed corridors). Concerns exist regarding the potential safety, environmental and health effects on the public and on transportation workers due to electrification along new or existing rail corridors, and to maglev and high speed rail operations. Therefore, the characterization of electric and magnetic fields (EMF) produced by both steady (dc) and alternating currents (ac) at power frequency (50 Hz in Europe and 60 Hz in the U.S.) and above, in the Extreme Low Frequency (ELF) range (3-3000 Hz) is of interest. An EMF survey of the Washington Metrorail (WMATA) transit system was performed, as part of a comprehensive comparative EMF safety assessment of the German Transrapid (TR-07) maglev system with other existing and advanced rail systems. The report provides the Analysis (Vol. I) of results, and detailed data and statistical summaries (Vol. II, Appendices) of representative EMF profiles on vehicles and facilities typical of this transit electrotechnology (third rail dc). EMF data represent a range of train operating conditions and locations (in vehicles, stations and waysides), as well as in traffic control and electrical power supply facilities.

  3. The Transportation Energy and Carbon Footprints of the 100 Largest U.S. Metropolitan Areas

    SciTech Connect

    Southworth, Frank; Sonnenberg, Anthon; Brown, Marilyn A

    2008-01-01

    We present estimates of the automobile and truck travel based energy and carbon footprints of the largest 100 U.S. metropolitan areas. The footprints are based on the estimated vehicle miles traveled and the transportation fuels consumed. Results are presented on an annual basis and represent end use emissions only. Total carbon emissions, emissions per capita, and emissions per dollar of gross metropolitan product are reported. Two years of annual data were examined, 2000 and 2005, with most of the in-depth analysis focused on the 2005 results. In section 2 we provide background data on the national picture and derive some carbon and energy consumption figures for the nation as a whole. In section 3 of the paper we examine the metropolitan area-wide results based on the sums and averages across all 100 metro areas, and compare these with the national totals and averages. In section 4 we present metropolitan area specific footprints and examine the considerable variation that is found to exist across individual metro areas. In doing so we pay particular attention to the effects that urban form might have on these differences. Finally, section 5 provides a summary of major findings, and a list of caveats that need to be borne in mind when using the results due to known limitations in the data sources used.

  4. Comparison of life-cycle energy and emissions footprints of passenger transportation in metropolitan regions

    NASA Astrophysics Data System (ADS)

    Chester, Mikhail V.; Horvath, Arpad; Madanat, Samer

    2010-03-01

    A comparative life-cycle energy and emissions (greenhouse gas, CO, NO X, SO 2, PM 10, and VOCs) inventory is created for three U.S. metropolitan regions (San Francisco, Chicago, and New York City). The inventory captures both vehicle operation (direct fuel or electricity consumption) and non-operation components (e.g., vehicle manufacturing, roadway maintenance, infrastructure operation, and material production among others). While urban transportation inventories have been continually improved, little information exists identifying the particular characteristics of metropolitan passenger transportation and why one region may differ from the next. Using travel surveys and recently developed transportation life-cycle inventories, metropolitan inventories are constructed and compared. Automobiles dominate total regional performance accounting for 86-96% of energy consumption and emissions. Comparing system-wide averages, New York City shows the lowest end-use energy and greenhouse gas footprint compared to San Francisco and Chicago and is influenced by the larger share of transit ridership. While automobile fuel combustion is a large component of emissions, diesel rail, electric rail, and ferry service can also have strong contributions. Additionally, the inclusion of life-cycle processes necessary for any transportation mode results in significant increases (as large as 20 times that of vehicle operation) for the region. In particular, emissions of CO 2 from cement production used in concrete throughout infrastructure, SO 2 from electricity generation in non-operational components (vehicle manufacturing, electricity for infrastructure materials, and fuel refining), PM 10 in fugitive dust releases in roadway construction, and VOCs from asphalt result in significant additional inventory. Private and public transportation are disaggregated as well as off-peak and peak travel times. Furthermore, emissions are joined with healthcare and greenhouse gas monetized

    Transportation noise is known to have negative impact on both public health and life quality. This study evaluated the relationship between transportation noise and annoyance levels, and also the difference of annoyance levels in two metropolitan cities based on epidemiologic surveys. Two thousand adult subjects living in Seoul and Ulsan were enrolled by stratified random sampling on the basis of noise maps from July 2015 to January 2016. Individual annoyance in accordance with transportation noise levels in two metropolitan cities were surveyed using an 11-point visual analog scale questionnaire. The results show that transportation noise level was significantly correlated with annoyance in both cities. Logistic regression analysis revealed that the risk of being 'highly annoyed' increased with noise level (Ldn, day-night average sound level) in both cities. After adjusting for age, residence period, sociodemographic factors (sex, education, marriage, income, alcohol, smoking, and exercise) and noise sensitivity, the risk of being 'highly annoyed' was increased with noise levels in both cities. In comparison to those of areas with noise levels below 55 dBA, the adjusted odds ratios of 'highly annoyed' for areas with 55-65 dBA and over 65 dBA were 2.056 (95% confidence interval [CI] 1.225-3.450), 3.519 (95% CI 1.982-6.246) in Seoul and 1.022 (95% CI 0.585-1.785), 1.704 (95% CI 1.005-2.889) in Ulsan, respectively. Based on the results of a population study, we showed that transportation noise levels were significantly associated with annoyance in adults. However, there were some differences between the two cities. In this study, there were differences in transportation noise between the two cities. Seoul has complex noise (traffic and aircraft), compared to single road traffic noise in Ulsan. Therefore, single and complex transportation noise may have different effects on annoyance levels.

    Similar to most large cities, the transportation sector in the Mexico City Metropolitan Area (MCMA) constitutes the largest source of air pollution emissions, which result in significant impacts on human health. Although the majority of MCMA residents use public transportation, the share of trips in private vehicles is rising and these vehicles have become the largest contributor to mobile emissions. To reduce these emissions, there is an urgent need to improve the current fleet, improve the quality of fuels, and modify the paradigm of private car use, by providing clean, safe, efficient and comfortable public transportation options. Here we present the potential human health benefits of a set of five mobile source control measures that span public and private transportation options: Taxi fleet renovation, Hybrid buses, Metro Expansion, and the introduction of low sulfur gasoline and Tier II vehicles. We also discuss the methodology and preliminary results of the analysis of the implementation of the project for a Bus Rapid Transit system in Mexico City, in terms of its impacts on personal exposures, emissions, and public health.

    2015-09-01

    This study analyzed the association between self-reported diagnosis of hearing loss and individual and occupational factors among urban transportation workers in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. The sample size was calculated by quotas and stratified by occupation (drivers and fare collectors) in the urban transportation companies in Belo Horizonte, Betim, and Contagem. Data were collected with face-to-face interviews and recorded by the interviewers on netbooks. The dependent variable was defined as an affirmative response to the question on prevailing medical diagnosis of hearing loss. The independent variables were organized in three blocks: social and demographic characteristics, lifestyle, and work aspects. Diagnosis of hearing loss was reported by 213 of the 1,527 workers and was associated with age and diagnosis of tinnitus. At the occupational level, hearing loss was associated with history of sick leave, time-on-the-job, and two environmental risks, unbearable noise and whole-body vibration. Measures to prevent hearing loss are needed for urban transportation workers.

  19. Exploring relationships between building and transportation energy use of residents in U.S. metropolitan regions

    NASA Astrophysics Data System (ADS)

    Pede, Timothy J.

    There is much potential to decrease energy consumption in the U.S. by encouraging compact, centralized development. Although many studies have examined the extent to which built environment and demographic factors are related to household energy use, few have considered both building and transportation energy together. We hypothesized that residents living further from city centers, or urban cores, consume more energy for both purposes than their inner city counterparts, resulting in a direct relationship between building and transportation energy usage. This hypothesis was tested with two case studies. The first focused on New York City. Annual building energy per unit of parcels, or tax lots, containing large multi-family structures was compared to the daily transportation energy use per household of traffic analysis zones (TAZs) (estimated with a regional travel demand model). Transportation energy showed a strong spatial pattern, with distance to urban core explaining 63% of variation in consumption. Building energy use was randomly distributed, resulting in a weak negative correlation with transportation energy. However, both correlation with distance to urban core and transportation energy became significant and positive when portion of detached single-family units for TAZs was used as a proxy for building energy. Structural equation models (SEMs) revealed a direct relationship between log lot depth and both uses of energy, and inverse relationship between portion of attached housing units and transportation energy. This supports the notion that sprawling development increases both the building and transportation energy consumption of households. For the second analysis, annual building and automobile energy use per household were estimated for block groups across the 50 most populous U.S. metropolitan regions with Esri Consumer Expenditure Data. Both forms of energy consumption per household were lowest in inner cities and increased at greater distances from

    Migration pattern of organochloro pesticide lindane has been studied in groundwater of metropolitan city Vadodara. Groundwater flow was simulated using the groundwater flow model constructed up to a depth of 60 m considering a three-layer structure with grid size of 40 × 40 × 40 m(3). The general groundwater flow direction is from northeast to south and southwest. The river Vishwamitri and river Jambua form natural hydrologic boundary. The constant head in the north and south end of the study area is taken as another boundary condition in the model. The hydraulic head distribution in the multilayer aquifer has been computed from the visual MODFLOW groundwater flow model. TDS has been computed though MT3D mass transport model starting with a background concentration of 500 mg/l and using a porosity value of 0.3. Simulated TDS values from the model matches well with the observed data. Model MT3D was run for lindane pesticide with a background concentration of 0.5 μg/l. The predictions of the mass transport model for next 50 years indicate that advancement of containment of plume size in the aquifer system both spatially and depth wise as a result of increasing level of pesticide in river Vishwamitri. The restoration of the aquifer system may take a very long time as seen from slow improvement in the groundwater quality from the predicted scenarios, thereby, indicating alarming situation of groundwater quality deterioration in different layers. It is recommended that all the industries operating in the region should install efficient effluent treatment plants to abate the pollution problem.

    Estimate the health risks and benefits of mode shifts from car to cycling and public transport in the metropolitan area of Barcelona, Spain. We conducted a health impact assessment (HIA), creating 8 different scenarios on the replacement of short and long car trips, by public transport or/and bike. The primary outcome measure was all-cause mortality and change in life expectancy related to two different assessments: A) the exposure of travellers to physical activity, air pollution to particulate matter <2.5 μm (PM2.5), and road traffic fatality; and B) the exposure of general population to PM2.5, modelling by Barcelona Air-Dispersion Model. The secondary outcome was a change in emissions of carbon dioxide. The annual health impact of a shift of 40% of the car trips, starting and ending in Barcelona City, to cycling (n=141,690) would be for the travellers who shift modes 1.15 additional deaths from air pollution, 0.17 additional deaths from road traffic fatality and 67.46 deaths avoided from physical activity resulting in a total of 66.12 deaths avoided. Fewer deaths would be avoided annually if half of the replaced trips were shifted to public transport (43.76 deaths). The annual health impact in the Barcelona City general population (n=1,630,494) of the 40% reduction in car trips would be 10.03 deaths avoided due to the reduction of 0.64% in exposure to PM2.5. The deaths (including travellers and general population) avoided in Barcelona City therefore would be 76.15 annually. Further health benefits would be obtained with a shift of 40% of the car trips from the Greater Barcelona Metropolitan which either start or end in Barcelona City to public transport (40.15 deaths avoided) or public transport and cycling (98.50 deaths avoided).The carbon dioxide reduction for shifting from car to other modes of transport (bike and public transport) in Barcelona metropolitan area was estimated to be 203,251t/CO₂ emissions per year. Interventions to reduce car use and

    Atmospheric aerosols have adverse effects on human health, contribute to the visibility reduction and influence the energy balance of the planet. A three-dimensional chemical transport model (PMCAMx) (Gaydos et al., 2007) is used to simulate the particular matter (PM) mass composition distribution in the Mexico City Metropolitan Area (MCMA). PMCAMx uses the framework of CAMx (ENVIRON, 2002) modelling the processes of horizontal and vertical advection, horizontal and vertical dispersion, wet and dry deposition, and gas-phase chemistry. In addition to the above, PMCAMx includes three detailed aerosol modules: inorganic aerosol growth (Gaydos et al., 2003; Koo et al., 2003a), aqueous-phase chemistry (Fahey and Pandis, 2001), and secondary organic aerosol formation and growth (Koo et al., 2004). The aerosol thermodynamic model ISORROPIA has been improved as it now simulates explicitly the chemistry of Ca, Mg, and K salts and is linked to PMCAMx. The hybrid approach (Koo et al., 2003b) for modelling aerosol dynamics is applied in order to accurately simulate the inorganic components in coarse mode. This approach assumes that the smallest particles are in equilibrium while the condensation/evaporation equation is solved for the larger ones. The new CMU organic aerosol model, which is based on the splitting of the organic aerosol volatility range in discrete bins, is also used. The model predictions are evaluated against the PM and vapour concentration measurements from the MCMA-2003 Campaign (Molina et al., 2007).

    Prior to 2008, transfers of radioactive material within the Savannah River Site (SRS) boundary, referred to as onsite transfers, were authorized by Transportation Safety Basis (TSB) documents that only required approval by the SRS contractor. This practice was in accordance with the existing SRS Transportation Safety Document (TSD). In 2008 the Department of Energy Savannah River Field Office (DOE-SR) requested that the SRS TSD be revised to require DOE-SR approval of all Transportation Safety Basis (TSB) documents. As a result, the primary SRS contractor embarked on a multi-year campaign to consolidate old or generate new TSB documents and obtain DOE-SR approval for each. This paper focuses on the challenges incurred during the rewriting or writing of and obtaining DOE-SR approval of all Savannah River Site Onsite Transportation Safety Basis documents.

  1. Atmospheric transport of pesticides in the Sacramento, California, metropolitan area, 1996-1997

    Majewski, Michael S.; Baston, David S.

    2002-01-01

    Weekly composite, bulk air was sampled with respect to wind speed and direction from January 1996 through December 1997 in one urban and two agricultural locations in Sacramento County, California. The sampling sites were located along a north-south transect, the dominant directions of the prevailing winds. The samples were analyzed for a variety of current-use pesticides, including dormant orchard spray insecticides and rice herbicides. A variety of pesticides were detected throughout the year, predominantly chlorpyrifos, diazinon, and trifluralin. The data obtained during the winter and spring suggest that some pesticides used in agricultural areas become airborne and may be transported into the urban area. Confirmation of this drift is difficult, however, because these three predominant pesticides, as well as other detected pesticides, also are heavily used in the urban environment. The spring data clearly show that molinate and thiobencarb, two herbicides used only in rice production, do drift into the urban environment.

    Background Changes in urban mobility play a major role in transforming metropolitan areas into healthier places. This study quantified the impact of changes in travel mode shift and trip distance on active and non-active transportation of working age adult population of São Paulo. Methods and findings Through different scenarios, we estimated the daily time spent in transportation per inhabitant (divided in active and non-active transportation time) and the proportion of inhabitants accumulating 30 min or more of daily active transportation. The replacement of individual for collective motorized modes in long distance trips (> 1000 m) in combination with the substitution of long for short trips positively impacted all outcomes. Compared to the current situation, there was an increase in the active transportation time (from 19.4 to 26.7 min/inhabitant), which also increased the proportion of adults active for transportation (from 27.6% to 35.4%). Additionally, the non-active transportation time decreased (from 67.0 to 26.2 min/inhabitant), which helped to reduce the total time spent in transportation (from 86.4 to 52.9 min/inhabitant). Conclusion Transport and urban planning policies to reduce individual motorized trips and the number of long trips might produce important health benefits, both by increasing population levels of active transportation and reducing the non-active and the total time of daily trips.

    2016-11-01

    Fine particulate matter (PM2.5) emissions from vegetation fires can be transported over long distances and may cause significant air pollution episodes far from the fires. However, epidemiological evidence on health effects of vegetation-fire originated air pollution is limited, particularly for mortality and cardiovascular outcomes. We examined association between short-term exposure to long-range transported PM2.5 from vegetation fires and daily mortality due to non-accidental, cardiovascular, and respiratory causes and daily hospital admissions due to cardiovascular and respiratory causes in the Helsinki metropolitan area, Finland. Days significantly affected by smoke from vegetation fires between 2001 and 2010 were identified using air quality measurements at an urban background and a regional background monitoring station, and modelled data on surface concentrations of vegetation-fire smoke. Associations between daily PM2.5 concentration and health outcomes on i) smoke-affected days and ii) all other days (i.e. non-smoke days) were analysed using Poisson time series regression. All statistical models were adjusted for daily temperature and relative humidity, influenza, pollen, and public holidays. On smoke-affected days, 10µg/m(3) increase in PM2.5 was associated with a borderline statistically significant increase in cardiovascular mortality among total population at a lag of three days (12.4%, 95% CI -0.2% to 26.5%), and among the elderly (≥65 years) following same-day exposure (13.8%, 95% CI -0.6% to 30.4%) and at a lag of three days (11.8%, 95% CI -2.2% to 27.7%). Smoke day PM2.5 was not associated with non-accidental mortality or hospital admissions due to cardiovascular causes. However, there was an indication of a positive association with hospital admissions due to respiratory causes among the elderly, and admissions due to chronic obstructive pulmonary disease or asthma among the total population. In contrast, on non-smoke days PM2.5 was generally

  1. Urban density and the metabolic reach of metropolitan areas: A panel analysis of per capita transportation emissions at the county-level.

    PubMed

    Ergas, Christina; Clement, Matthew; McGee, Julius

    2016-07-01

    We engage a tension in the urban environment literature that positions cities as both drivers of environmental destruction and loci of environmental protection. We argue that the traditional binary view of cities as either harmful or beneficial is too simplistic; we advance a more nuanced understanding of cities to study their internal and external metabolic effects in terms of carbon emissions from on-road transportation at the county-level across the continental United States between 2002 and 2007. First, utilizing satellite imagery from the National Land Cover Database, we create a novel measure of population density by quantifying the number of people per square mile of impervious surface area. Second, we develop a measure of metropolitan adjacency from the rural classifications datasets published by the USDA. In spatial regression models, we find that while higher density reduces emissions, counties that are geographically isolated from metropolitan areas actually have lower per capita emissions, all else equal. We elaborate on the conceptual, methodological, and practical implications of our study in the conclusion.

  6. Secondhand smoke in public places: can Bangalore metropolitan transport corporation be a role model for effective implementation of Cigarette and Other Tobacco Products Act, 2003?

    The Indian government enacted 'The cigarettes and other tobacco products act, 2003' (COTPA), which prohibits smoking in public places. To validate the efficacy of the Act of 2003, enacted by the Government of India, to prevent secondhand smoking in public places. The study is based on a non-random sample survey of 2,600 bus passengers carried out in the premises of three mega public road transport organizations in Karnataka state, India, in June 2007. The information was gathered through administration of structured schedules. A sample of 1,000 each for the terminus of Bangalore Metropolitan Transport Corporation (BMTC) and Karnataka State Road Transport Corporation (KSRTC) in Bangalore and, 600 for North West Karnataka Road Transport Corporation (NWKRTC) in Hubli-Dharwad city was distributed proportionately according to the number of platforms in each terminus. Simple Averages. There is some reduction in smoking in general as perceived by 69% of the passengers as compared to the scenario a year before the enactment of COTPA. The observed smoking is lower in the bus premises of BMTC where there is strict regulation, and higher in the bus premises of NWKRTC, which has not taken any regulatory measures. Knowing smoking is banned in public places can itself create awareness depending on the coverage extended by media and implementing an agency to reach the public. The implementation of an act depends on the willingness of stakeholders to act upon it. The implementation of COTPA as done by BMTC could well become a role model for replication elsewhere, if BMTC can strive harder to accomplish a 100% smoke-free zone.

  7. Environmental Inequality in Metropolitan America

    Downey, Liam; Dubois, Summer; Hawkins, Brian; Walker, Michelle

    2009-01-01

    This study compares the environmental hazard burden experienced by Blacks, Hispanics, Pacific Islanders, Native Americans, Asian Americans, and Whites in each of the 329 metropolitan areas in the continental United States, using toxicity-weighted air pollutant concentration data drawn from the Environmental Protection Agency's Risk-Screening Environmental Indicators project to determine whether and to what degree environmental inequality exists in each of these metropolitan areas. After demonstrating that environmental inequality outcomes vary widely across metropolitan areas and that each group in the analysis experiences a high pollution disadvantage in multiple metropolitan areas and a medium pollution disadvantage in many metropolitan areas, the authors test three hypotheses that make predictions about the role that residential segregation and racial income inequality play in producing environmental inequality. Using logistic regression models to test these hypotheses, the authors find that residential segregation and racial income inequality are relatively poor predictors of environmental inequality outcomes, that residential segregation can increase and decrease racial/ethnic group proximity to environmental hazards, and that the roles income inequality and residential segregation play in producing environmental inequality vary from one racial/ethnic group to another.

    Urban trends in Mexico from 1960 to 1980 are analyzed using multivariate analysis techniques. The authors note that the total number of metropolitan regions has increased from 12 to 26 during this period. Differences between the stage in urbanization reached by the Mexico City region and other urban centers in the country are noted. In Mexico City, the authors observe a decline in the population of the central city region coupled with rapid growth in the surrounding municipalities. (SUMMARY IN ENG)

  19. Commuters' exposure to PM 2.5, CO, and benzene in public transport in the metropolitan area of Mexico City

    NASA Astrophysics Data System (ADS)

    Gómez-Perales, J. E.; Colvile, R. N.; Nieuwenhuijsen, M. J.; Fernández-Bremauntz, A.; Gutiérrez-Avedoy, V. J.; Páramo-Figueroa, V. H.; Blanco-Jiménez, S.; Bueno-López, E.; Mandujano, F.; Bernabé-Cabanillas, R.; Ortiz-Segovia, E.

    A survey was carried out to measure commuters' exposure to PM 2.5, CO, benzene, and the chemical composition of PM 2.5 on different routes and modes of transport in Mexico City. PM 2.5 ( n=62), CO ( n=54) and benzene ( n=22) are presented from morning (6:30-9:30 a.m.) and evening (17:30-20:30) rush hours on minibuses, buses and Metro (underground or subway system). Three routes were selected from a previous commuters' exposure study covering some of the most important thoroughfares of the valley. For PM 2.5, mass concentration was determined for all the samples. Nitrates, sulphates, inorganic elements and carbon fraction were analysed. CO was sampled using electrochemical sensors and 6-l canisters with flow controller devices were used to collect integrated samples for benzene. Minibuses had a slightly higher geometric mean PM 2.5 concentration in the morning than other modes of transport, but the ranking of geometric mean PM 2.5 by mode of transport is opposite in the evening and the variability within modes is approximately double the difference between modes. The highest single measurement was a concentration of 137 μg m -3 on a bus during an evening rush hour. The main component identified in PM 2.5 was carbon. Carbon monoxide levels in this study were approximately 3 times lower than those found in a commuter exposure study conducted in 1991. A strong association was shown between wind speed and PM 2.5 exposure in minibuses ( r2=0.50) and buses ( r2=0.54). The relationship between wind speed and CO exposure was strong only in minibuses ( r2=0.52).

    The world s metropolitan carbon footprints have distinct geographies that are not well understood or recognized in debates about climate change, partly because data on greenhouse gas emissions is so inadequate. This article describes the results of the most comprehensive assessment of carbon footprints for major American metropolitan areasavailable to date, focusing on residential and transportation carbon emissions for the largest 100 metropolitan areas in the United States. These findings are put into the context of effortsacross the country and the globe to characterize carbon impacts and policy linkages.

  18. Metropolitan Lima: area profile.

    PubMed

    Hakkert, R

    1986-11-01

    This profile of metropolitan Lima, Peru, covers administrative divisions; population growth; age distribution; ethnicity and religion; housing and households; education and health care; economic activity, income, and consumption; transport and communication; and sources of information. Nearly 30% of Peru's entire population and 42% of its urban population live in Lima. The trend continues, yet Lima's urban primacy is waning due to the growth of some regional centers like Trujillo and Chimbote. Lima is still almost 10 times as large as the country's next ranking cities, Trujillo on the northern coast and Arequipa in the south. Peru's main administrative divisions are the 24 departments, of which the Department of Lima is one. These departments are further divided into 156 provinces. Greater Lima consists of 2 such provinces, the province of Lima and the constitutional province of Callao. Although the population of Lima continues to grow, its rate of growth slowed from about 5.5% during the 1960s to about 3.9% in the 1970s. Current projections estimate a metropolitan population of 6.7 million by 1990. On the whole, Lima's age structure is somewhat older than that of the rest of Peru. The median age of the population is 22.3 years, compared to a national figure of 20.4. The proportion of persons over age 65 is only 3.6%, lower than the national average of 4.1%, due to the tendency of in-migration to concentrate people of intermediate ages in the cities. Almost 400,000 inhabitants of greater Lima are bilingual in Spanish and an indigenous language. As elsewhere in Peru, the dominant religion is Roman Catholicism. Lima is a spread out city with few high rise buildings due to the danger of earthquakes. Only 12% of Lima's households are found in apartment buildings. As in other cities of Latin America, the formal housing market is beyond the reach of a major segment of the population. Consequently, much of the urban settlement has occurred through informal self

    SL3-88-222 (18 Sept. 1973) --- The metropolitan area of Chicago is encompassed in this Skylab 3 Earth Resources Experiments Package (EREP) S190-B photograph taken on Sept. 18, 1973 from the Skylab space station cluster in Earth orbit. The surrounding major cities of Aurora and Joliet, Illinois; Hammond, Gary and East Chicago, Indiana, are easily delineated. The photograph reveals the following: (1) Cultural differentiation of commercial, industrial and residential areas for use in population and social studies in micro-macro community planning and in cultural pattern studies in the improvement of urban areas. (Aurora is one of 27 census cities of interest to Robert Alexander, a principal investigator. Alexander is with the U.S. Geological Survey). (2) The transportation network with major corridors and their interchanges, primary and feeder streets for use in network analysis and in the development of models for population movement and land use projection. (3) The agricultural lands for land use identification on crop inventory analysis; airports for use in delineation of service and infringement of major man-made features that affect ecosystem balance (support to environmental impact studies). (4) Air and water plumes for use in case studies, natural and man-made differentiation of pollution sources, in support of model development and in ecosystem research studies on the effects of pollution. (5) Recreational centers for use in relating recreational centers to population centers, establishing possible demands and in development of possible future recreational centers to support the demand. All EREP photography is available to the public through the Department of Interior?s Earth Resources Observations Systems Data Center, Sioux Falls, South Dakota, 57198. Photo credit: NASA

    2014-02-01

    There is an interaction between land use, transportation, and environment in improving and managing urban quality. One of the concpets to integrate those three aspects is Transit Oriented Development (TOD). It is a concept for managing urban growth in transit corridors which have characteristics of mixed land use, compact, walkability, and development focused around public transit area. This research aims at utilizing GIS to organize, sort, and analyze spatial data including aspects of land use, transportation, and environment. Jabodetabek is a strategic metropolitan area in Indonesia, and consists of DKI Jakarta and the neighboring Bodetabek cities, with more than 27 million population in 2010. Approximately 1,105,000 people are entering Jakarta every workday from the negihboring Bodetabek region. The surge in the number of passenger cars and motorcycles is astonishing. In contrast, the usage of public transport has declined deeply. Public transport infrastructure development without the integration of TOD may not attain the objective of reducing car dependency. This paper discusses the study which was carried out to identify the applicability of TOD principles in Jabodetabek using GIS as a tool to analysis and create model.

  1. Breast and cervical cancer screening among women in metropolitan areas of the United States by county-level commuting time to work and use of public transportation, 2004 and 2006

    PubMed Central

    2010-01-01

    Background Commuting times and behaviors have been associated with a variety of chronic disease outcomes and health behaviors. We examined the relationships between ecologic measures of commuting time and use of public transportation in relation to breast and cervical cancer screening among women in U.S. metropolitan areas who participated in the 2004 and 2006 Behavioral Risk Factor Surveillance System (BRFSS) surveys. Methods Self-reported county of residence was used to classify respondents as residents of metropolitan statistical areas (MSAs). Only BRFSS respondents who resided in the 39 MSAs with a population of ≥ 1.5 million in 2007--representing a total of 337 counties--were included in this analysis. A total of 76,453 women aged ≥ 40 years were included in analyses on mammography. Analyses on Pap testing were limited to women aged ≥18 years with no history of hysterectomy (n = 80,959). Area-based measures of socio-economic status (SES) were obtained by utilizing county-level information from the 2000 U.S. Census. Results With adjustment for age, no important associations were observed between receipt of a recent mammogram and either a county-level measure of commute time or residence in an area where more residents had access to a car. Similarly, women living in counties where at least four percent of the residents used public transportation were as likely to have had a recent mammogram or Pap test compared with women in areas where less than four percent of residents used public transportation. However, women living in counties where < 2% of residents had no access to a car were somewhat more likely to have had a Pap test in the past 3 years than women in areas where ≥ 3% of the residents had no access to a car (87.3% versus 84.5%; p-value for test for trend < 0.01). In multivariate analysis, living in a county with a median commute time of at least 30 minutes was not significantly associated with having had a Pap test in the past 3 years (adjusted

  6. Assessment of Quality Assurance Measures for Radioactive Material Transport Packages not Requiring Competent Authority Design Approval - 13282

    SciTech Connect

    Komann, Steffen; Groeke, Carsten; Droste, Bernhard

    2013-07-01

    The majority of transports of radioactive materials are carried out in packages which don't need a package design approval by a competent authority. Low-active radioactive materials are transported in such packages e.g. in the medical and pharmaceutical industry and in the nuclear industry as well. Decommissioning of NPP's leads to a strong demand for packages to transport low and middle active radioactive waste. According to IAEA regulations the 'non-competent authority approved package types' are the Excepted Packages and the Industrial Packages of Type IP-1, IP-2 and IP-3 and packages of Type A. For these types of packages an assessment by the competent authority is required for the quality assurance measures for the design, manufacture, testing, documentation, use, maintenance and inspection (IAEA SSR 6, Chap. 306). In general a compliance audit of the manufacturer of the packaging is required during this assessment procedure. Their regulatory level in the IAEA regulations is not comparable with the 'regulatory density' for packages requiring competent authority package design approval. Practices in different countries lead to different approaches within the assessment of the quality assurance measures in the management system as well as in the quality assurance program of a special package design. To use the package or packaging in a safe manner and in compliance with the regulations a management system for each phase of the life of the package or packaging is necessary. The relevant IAEA-SSR6 chap. 801 requires documentary verification by the consignor concerning package compliance with the requirements. (authors)

  7. Perceptions and attitudes toward workplace transport risks: a study of industrial lift truck operators in a London authority.

    PubMed

    Majekodunmi, Adekunle; Farrow, Alexandra

    2009-01-01

    Workplace transport risks remain the second largest cause of work-related fatal and major injuries in the UK. In the period 2004-2005, of the 5,427 workplace transport injuries, 68 were fatal and industrial lift trucks were associated with 24% of accidents. This study aimed to quantify risk perceptions and attitudes of lift truck operators for workplace transport risks and to ascertain opinions on common accidents, risk factors, and control measures. The cross-sectional study design with a postal questionnaire collected data in a population of lift truck operators (n = 140). Questions related to training and experience; perception of risks; safety attitudes, awareness, and knowledge; and safety responsibility. A response rate of 61% (n = 86) indicated lift truck operators had a high perception of workplace transport risks. Common lift truck incidents were considered "very serious" while respondents demonstrated a good knowledge of accident risk factors and control measures. Greater support was called for from employers and regulatory authorities to improve workplace safety. Recommendations include future safety initiatives for lift truck operators. These may be useful to organisations and enforcing authorities charged with safety obligations.

  8. Multiplex networks in metropolitan areas: generic features and local effects.

    2015-10-06

    Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems of coupling different modes and we report in this paper an empirical analysis of the coupling between the street network and the subway for the two large metropolitan areas of London and New York. We observe a similar behaviour for network quantities related to quickest paths suggesting the existence of generic mechanisms operating beyond the local peculiarities of the specific cities studied. An analysis of the betweenness centrality distribution shows that the introduction of underground networks operate as a decentralizing force creating congestion in places located at the end of underground lines. Also, we find that increasing the speed of subways is not always beneficial and may lead to unwanted uneven spatial distributions of accessibility. In fact, for London—but not for New York—there is an optimal subway speed in terms of global congestion. These results show that it is crucial to consider the full, multimodal, multilayer network aspects of transportation systems in order to understand the behaviour of cities and to avoid possible negative side-effects of urban planning decisions. © 2015 The Author(s).

  9. Comparison of minimum space allowance standards for transportation of cattle by road from 8 authorities.

    PubMed

    Whiting, T L

    2000-11-01

    Space allowance for animals in transit is a consistent concern in many countries developing codes of practice and regulations to assure humane treatment of food producing animals. Describing minimum space allowance requirements for cattle in transit has proven to be difficult, as the space required increases as the animal grows. Loading pressure, defined as weight of live animal per unit area, has proven to be a clear method of communicating with transporters and inspection staff what the maximum safe stocking limit is based on individual animal weight. The loading density recommendations in the Canadian code of practice for beef cattle are compared with other standards by using loading pressure charts as a visual aid. Loading pressure charts are recommended in preference to a tabular format to describe the minimal space allowed per animal for cattle transported by road.

  11. Metropolitan-scale Transport and Dispersion from the New York World Trade Center Following September 11, 2001. Part II: An Application of the CALPUFF Plume Model

    NASA Astrophysics Data System (ADS)

    Gilliam, Robert C.; Huber, Alan H.; Raman, Sethu

    2005-10-01

    Following the collapse of the New York World Trade Center (WTC) towers on September 11, 2001, Local, State, and Federal agencies initiated numerous air monitoring activities to better understand the ongoing impacts of emissions from the disaster. The collapse of the World Trade Center towers and associated fires that lasted for several weeks resulted at times in a noticeable plume of material that was dispersed around the Metropolitan New York City (NYC) area. In general, the plume was only noticeable for a short period of time following September 11, and only apparent close to the World Trade Center site. A study of the estimated pathway which the plume of WTC material would likely follow was completed to support the United States Environmental Protection Agency’s 2002 initial exposure assessments. In this study, the WTC emissions were simulated using the CALMET-CALPUFF model in order to examine the general spatial and temporal dispersion patterns over NYC. This paper presents the results of the CALPUFF plume model in terms of plume dilution and location, since the exact source strength remains unknown. Independent observations of PM2.5 are used to support the general dispersion features calculated by the model. Results indicate that the simulated plume matched well with an abnormal increase (600 1000% of normal) in PM2.5 two nights after the WTC collapse as the plume rotated north to southeast, towards parts of NYC. Very little if any evidence of the plume signature was noted during a similar flow scenario a week after September 11. This leads to the conclusion that other than areas within a few kilometers from the WTC site, the PM2.5 plume was not observable over NYC’s background concentration after the first few days.

    1991-06-01

    The report evaluates the economic and social impacts of supporting the Southeast Pennsylvania Transportation Authority (SEPTA) public transportation system. The study is comprehensive, considering travel times and costs for individual travelers, and how those changes would affect the cost of doing business, individual spending patterns, and the regional and State economies. Four alternatives were considered: rehabilitation of the system and continuation of services, a fifty-percent scaleback of services, gradual shutdown of the system over ten years, and immediate shutdown. The analysis showed that rehabilitation of the system would return three dollars to the region for every dollar spent on it, and that cutting back service would have economic costs far greater than any savings accrued. The methodology is general, and can be applied in other areas.

    Sixty “Mega Cities” would emerge by 2015 catering of 600 million populations, and were threatened by the climate change, because of cyclones, flooding, etc. Jakarta became a metro region covering Jakarta, Bogor, Tangerang, Bekasi, Depok and Cianjur. Jakarta metropolitan faced the very high population growth, urban sprawling, traffic jams, flooding, green open space reduction, environmental degradation, urban slums and illegal street hawkers. Flooding and traffic congestions were the two most important issues to solve. SWOT analysis and urban design solutions were produced to create a sustainable solution. Related to transportation issues, Singapore Mass Rapid Transport (MRT) concept was evaluated. Meanwhile the Netherlands’ polder concept as well as Singapore’s Integrated Water Management were also analyzed. The development of above ground MRT as well as Busway could be developed to connect Jakarta Metropolitan Region. The networks were developed on the main toll road networks. The MRT and Busway would eventually replace the need of automobile use in the future. The Transit - Oriented - Development (TOD) with high density can be suggested to be concentrated nearby the MRT and Busway interchange stations. The Netherlands’ polder and were adopted for urban’ low-lying lands in Jakarta Metropolitan Region, A polder system was defined as the Integrated Man-made Drainage System consisting Dikes, Drains, Retention Ponds, Outfall Structures or Pumping Stations. The polder system was proposed to be extended to Tangerang and Bekasi area.

  7. Emissions inventory for the Mexico City Metropolitan Area

    The emissions inventory bears a broad relationship to the energy balance, reflecting the dependence of the emissions with reference to the use of energy. Actually the consumption of gasoline and diesel fuel in the transport sector represents collectively, the greatest comparative expense of energy and the major contributor of the ozone precursor pollutants HC, NO{sub x} and CO, relative to the total volume of emissions in the Mexico City Metropolitan Area (MCMA). Also, the industrial sector introduces significant emissions of SO{sub 2} and NO{sub x} due to its energy consumption of fuel oils and natural gas. In contrast, the great majority of suspended particulate in the MCMA emanate from degradation processes of surface soil along the periphery of the urban zone. To the federal and local authorities charged with the design of strategies for prevention and control of atmospheric pollution, the emissions inventory is a strategic tool that reflects the relative intensity of the various emitters to the load capacity of the atmosphere. A comprehensive inventory was compiled for 1995, categorizing the emissions generated by four sectors: industry, services, transport and surface soils and vegetation, considering the following pollutants: TSP, SO{sub 2}, NO{sub x}, HC and CO. The combined pollutant emissions are 4,009,628 tons/year of which 3% are generated by the industry, 10% by the services sector, 75% by the transport sector, and 12% by surface soils and vegetation.

    This discussion of the metropolitan area of Sao Paulo, Brazil focuses on: administrative divisions; diversity and population growth; households, fertility, and mortality; migration; ethnicity, race, and religion; housing; transport; labor and income; and consumption. Currently, the metropolitan area of Sao Paulo, or Greater Sao Paula, is considered the 2nd largest urban agglomeration in Latin America after Mexico City. An estimated 9.5 million people live within the 583 square mile area of the central city. Another 5 million people live in 1 of the 36 other municipalities included in the metropolitan area which includes all 37 municipalities. Central city refers to the municipalities of Sao Paulo and Osasco. The city of Sao Paulo refers only to the municipality of Sao Paulo. The metropolitan area contains 3110 square miles in total and is still the smallest of the 11 administrative regions that comprise the State of Sao Paulo. The population, urban infrastructure, and economic activities are unevenly spread among the 37 municipalities. Greater Sao Paulo's population grew an average of 4.5 year during the 1970, down slightly from a peak of 5.9 year in the 1950s. The central city has a current growth rate of 3.7, a year, with the increase concentrated mainly in the southern and eastern districts that are removed from the city center and where land prices are still relatively low. Mortality plays a minor role in the population trends of Sao Paulo. Fertility is now slowly becoming the dominant factors in its natural increase. The average number of children a woman will bear is 3.3 in the metropolitan area and 3 in the city, low compared with the Brazilian national average of 4.2 children. According to a 1978 survey, 60% of the women use some form of birth control. The most common methods are oral contraceptives 27%, and sterilization, 15%. Despite declining fertility, the birthrate of the metropolitan area increased from 26 in 1970 to 30 in 1980 because of the changes

  13. The rhetoric and realities of integrating air quality into the local transport planning process in English local authorities.

    PubMed

    Olowoporoku, Dotun; Hayes, Enda; Longhurst, James; Parkhurst, Graham

    2012-06-30

    Regardless of its intent and purposes, the first decade of the Local Air Quality Management (LAQM) framework had little or no effect in reducing traffic-related air pollution in the UK. Apart from the impact of increased traffic volumes, the major factor attributed to this failure is that of policy disconnect between the process of diagnosing air pollution and its management, thereby limiting the capability of local authorities to control traffic-related sources of air pollution. Integrating air quality management into the Local Transport Plan (LTP) process therefore presents opportunities for enabling political will, funding and joined-up policy approach to reduce this limitation. However, despite the increased access to resources for air quality measures within the LTP process, there are local institutional, political and funding constraints which reduce the impact of these policy interventions on air quality management. This paper illustrate the policy implementation gaps between central government policy intentions and the local government process by providing evidence of the deprioritisation of air quality management compared to the other shared priorities in the LTP process. We draw conclusions on the policy and practice of integrating air quality management into transport planning. The evidence thereby indicate the need for a policy shift from a solely localised hotspot management approach, in which the LAQM framework operates, to a more holistic management of vehicular emissions within wider spatial administrative areas.

  14. Air pollution holiday effect in metropolitan Kaohsiung

    Tan, P.; Chen, P. Y.

    2014-12-01

    Different from Taipei, the metropolitan Kaohsiung which is a coastal and industrial city has the major pollution sources from stationary sources such as coal-fired power plants, petrochemical facilities and steel plants, rather than mobile sources. This study was an attempt to conduct a comprehensive and systematical examination of the holiday effect, defined as the difference in air pollutant concentrations between holiday and non-holiday periods, over the Kaohsiung metropolitan area. We documented evidence of a "holiday effect", where concentrations of NOx, CO, NMHC, SO2 and PM10 were significantly different between holidays and non-holidays, in the Kaohsiung metropolitan area from daily surface measurements of seven air quality monitoring stations of the Taiwan Environmental Protection Administration during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2010. Concentrations of the five pollutants were lower in the CNY than in the NCNY period, however, that of O3 was higher in the CNY than in the NCNY period and had no holiday effect. The exclusion of the bad air quality day (PSI > 100) and the Lantern Festival Day showed no significant effects on the holiday effects of air pollutants. Ship transportation data of Kaohsiung Harbor Bureau showed a statistically significant difference in the CNY and NCNY period. This difference was consistent with those found in air pollutant concentrations of some industrial and general stations in coastal areas, implying the possible impact of traffic activity on the air quality of coastal areas. Holiday effects of air pollutants over the Taipei metropolitan area by Tan et al. (2009) are also compared.

    Single entry communities (SECs) and cul-de-sacs minimize route choices and increase trip distance. Las Vegas' built environment facilitates the examination of these variables and active transport to school (ATS) rates. The purpose of this study was to examine the influence of SECs and cul-de-sacs on ATS rates in Las Vegas, NV elementary children. Parental-reported data was collected from 11 elementary schools on ATS rates (n = 1217). SECs and cul-de-sacs were quantified for each school zone. Logistic regression models were used to predict ATS. 23.9% of students reported ATS all of the time and 31.4% some of the time. SECs per school zone ranged from 0 to 25 (mean = 11.9). Cul-de-sacs ranged from 12 to 315 (mean = 138.3). Some ATS use was predicted by distance from school (p ≤ 0.001;OR = 0.61), parental education (high school: p = 0.004;OR = 0.53, some college: p = 0.001;OR = 0.50, 4 year degree: p = 0.004;OR = 0.52) and cul-de-sacs (p ≤ 0.001;OR = 0.99). A separate model using distance from school (p ≤ 0.001;OR = 0.61), parental education (high school: p = 0.002;OR = 0.51, some college: p ≤ 0.001;OR = 0.45, 4 year degree: p ≤ 0.001;OR = 0.45) and SECs (p ≤ 0.001;OR = 0.96) predicted some ATS. All ATS use was predicted by distance from school (p ≤ 0.001;OR = 0.58), parental education (Grades 9-11: p = 0.05;OR = 0.61, high school: p ≤ 0.001;OR = 0.45, some college: p ≤ 0.001;OR = 0.41, 4 year degree: p ≤ 0.001;OR = 0.38) and SECs (p ≤ 0.001;OR = 0.97). A separate model using distance from school (p ≤ 0.001;OR = 0.58), parental education (Grades 9-11: p = 0.041;OR = 0.59, high school: p ≤ 0.001;OR = 0.47, some college: p ≤ 0.001;OR = 0.44, 4 year degree: p ≤ 0.001;OR = 0.43) and cul-de-sacs (p ≤ 0.001;OR = 0.99) predicted all ATS. Current findings reveal that both SECs and cul-de-sacs were predictors of ATS beyond distance. Students with

    Objectives. We investigated the frequency with which alcohol advertisements appeared on Massachusetts Bay Transportation Authority (MBTA) transit lines in Boston, MA, and we calculated adult and youths' exposure to the ads. Methods. We measured the nature and extent of alcohol advertisements on 4 Boston transit lines on 2 separate weekdays 1 month apart in June and July of 2008. We calculated weekday ad exposure for all passengers (all ages) and for Boston Public School student passengers (aged 11–18 years). Results. Alcohol ads were viewed an estimated 1 212 960 times across all Boston-area transit passengers during an average weekday, reaching the equivalent of 42.7% of that population. Alcohol ads were viewed an estimated 18 269 times by Boston Public School student transit passengers during an average weekday, reaching the equivalent of 54.1% of that population. Conclusions. Advertisers reached the equivalent of half of all Boston Public School transit passengers aged 11 to 18 years and the equivalent of nearly half of all transit passengers in the Boston area with an alcohol advertisement each day. Because of the high exposure of underage youths to alcohol advertisements, we recommend that the MBTA prohibit alcohol advertising on the Boston transit system. PMID:19890170

    Contamination of major aquifers in highly densely populated areas is a major concern for stakeholders involved in the use and protection of groundwater resources. Sustainable groundwater withdrawal and management, and the identification of trends in groundwater contamination require a careful hydrochemical baseline characterization. This characterization is fundamental to investigate the presence and evolutionary trend of contaminants. In fact, it allows recovering and understanding: the spatial-temporal trend of contamination; the relative age of the contamination episodes; the reasons for anomalous behavior of some compounds during migration to and in the groundwater; the associations with which some contaminants can be found; the different behaviors in phreatic and semi-confined and confined aquifers. To attain such a characterization for the Milan metropolitan area (about 2,500 km2, ca 4.000.000 inhabitants, Lombardy, Italy), we carried out three main activities. (1) Collection of complete and reliable datasets concerning the geological, hydrogeological and hydrochemical (over 60,000 chemical analysis since 2003 to 2013) characteristics of the area and of the involved aquifers. This activity was very demanding because the available data are provided by different authorities (Lombardy Region, Provinces, Lombardy Environmental Agency - ARPA Lombardia, public own companies in charge of water system managements) in raw format and with different database standard, which required a large effort of manual verification and harmonization. (2) Completion of a hydrochemical characterization of the metropolitan area aquifers by classical statistical and multivariate statistical analyses, in order to define a baseline both for some major physical chemical characteristics and for the most relevant contaminants. (3) Development of a three dimensional hydrogeological model for the metropolitan area starting from the above listed datasets and existing models. This model will

    The purpose of the study was to examine professionals' awareness, knowledge, and experiences working with youth victims of sex trafficking in metropolitan and non-metropolitan communities. Professionals who worked with at-risk youth and/or crime victims were recruited from all counties in a southern, rural state in the U.S. to complete a telephone survey. Surveys included closed and open-ended questions, which were theme coded. Professionals' (n=289) were classified into one of four categories based on the counties in which they worked: metropolitan, micropolitan, rural, and all three community types. Although there were many similarities found in trafficking situations across the different types of communities, some expected differences were found. First, as expected, more professionals in metropolitan communities perceived CSEC as being a fairly or very serious problem in the state overall. Consistent with other studies, more professionals in metropolitan communities had received training on human trafficking and reported they were familiar with the state and federal laws on human trafficking (Newton et al., 2008). Significantly more professionals in metropolitan (54.7%) communities reported they had worked with a suspected or definite victim of STM compared to professionals in micropolitan communities (29.8%). There were few differences in victim characteristics, vulnerability factors, and trafficking situations (e.g., relationship to trafficker, traffickers' techniques for controlling victims, transportation, and Internet-facilitation of trafficking) across the community types. There is a continued need for awareness building of STM and training, particularly in non-metropolitan communities, as well as adoption of screening tools, integration of trauma-informed care, and identification of best practices.

    Ozone in the main air pollutant in Mexico City Metropolitan Area (MCMA). This kind of pollution is induced by the emissions of nitrogen oxides and hydrocarbons. According to Official Statistics National Air Pollution Quality Standard is exceeded over 300 days a year. Volatile hydrocarbons are generated in the cycle of storage transport and distribution of fuel (Gasoline Distribution Cycle). Above 17 millions of liters are handled daily in MCMA. Evaporative emission control is a complex task involving: floating roof tanks and vapor recovery units installation at bulk terminals and implementation of Phase 1 and Phase 2 vapor recovery systems at service stations. Since 1990, IMP has been involved in researching vapor emissions associated to gasoline storage and distribution cycle. Besides, the authors evaluate several technologies for bulk terminals and service stations. In this job, the authors present the results of an evaluation according to Mexican Official Standard of 500 vehicles. The gasoline vapors are trapped during refueling of cars and they are conduced to an equipment that includes an activated charcoal canister in order to adsorb them. Another Activated charcoal canister adsorbs ambient air as a reference. Experimental results showed that refueling hydrocarbon emissions are between 0.4 and 1.2 grams per liter with averages of 0.79 and 0.88 grams per liter according with two different gasoline types. These results were applied to Mexico City Vehicular fleet for the gasoline distribution cycle in order to obtain a total volatile hydrocarbon emission in Mexico City Metropolitan Area.

    The air quality in mass transport buses, especially air-conditioned buses may affect bus drivers who work full time. Bus numbers 16, 63, 67 and 166 of the Seventh Bus Zone of Bangkok Mass Transit Authority were randomly selected to investigate for microbial air quality. Nine air-conditioned buses and 2-4 open-air buses for each number of the bus (36 air-conditioned buses and 12 open-air buses) were included. Five points of in-bus air samples in each studied bus were collected by using the Millipore A ir Tester Totally, 180 and 60 air samples collected from air-conditioned buses and open-air buses were cultured for bacterial and fungal counts. The bus drivers who drove the studied buses were interviewed towards histories of work-related illness while working. The results revealed that the mean +/- SD of bacterial counts in the studied open-air buses ranged from 358.50 +/- 146.66 CFU/m3 to 506 +/- 137.62 CFU/m3; bus number 16 had the highest level. As well as the mean +/- SD of fungal counts which ranged from 93.33 +/- 44.83 CFU/m3 to 302 +/- 294.65 CFU/m3; bus number 166 had the highest level. Whereas, the mean +/- SD of bacterial counts in the studied air-conditioned buses ranged from 115.24 +/- 136.01 CFU/m3 to 244.69 +/- 234.85 CFU/m3; bus numbers 16 and 67 had the highest level. As well as the mean +/- SD of fungal counts which rangedfrom 18.84 +/- 39.42 CFU/m3 to 96.13 +/- 234.76 CFU/m3; bus number 166 had the highest level. When 180 and 60 studied air samples were analyzed in detail, it was found that 33.33% of the air samples from open-air buses and 6.11% of air samples from air-conditioned buses had a high level of bacterial counts (> 500 CFU/m3) while 6.67% of air samples from open-air buses and 2.78% of air samples from air-conditioned buses had a high level of fungal counts (> 500 CFU/m3). Data from the history of work-related illnesses among the studied bus drivers showed that 91.67% of open-air bus drivers and 57.28% of air-conditioned bus drivers had

    A study or urban population growth in Arab countries has 3 objectives: 1) examination at the micro level of recent demographic trends in selected metropolitan areas of the Arab world and their relationship to changes in the total and urban populations in the respective countries; 2) estimation of net migration by sex and broad age groups for each metropolitan area; and 3) analysis of the pattern of variation in the metropolitan growth rates and their components, migration and natural increase. The study covers the cities proper or urban agglomerations, which includes the suburbs, whose population exceeded 100,000 in the most recent census. Altogether, the study covers 49 metropolitan areas from 9 Arab countries--Algeria; Morocco; Tunisia; Libya; Egypt; Sudan; Syria; Iraq; and Kuwait. Analysis revealed that metropolitan growth rates do follow geographic patterns. In countries with an oil-based economy, metropolitan growth rates are high; in countries with unexploited resources they are slightly below the 1st group; and countries which have pressure on land have low metropolitan growth rates. Population size of the metropolitan area appears to be an important factor associated with variations in metropolitan growth rates and net migration rates. Natural increase emerges as the predominant factor in metropolitan growth, but the differentials in the growth rates are more clearly associated with variations in net migration rates. As all the possibilities of analysis of relationships of metropolitan growth have not been exhausted, it is proposed to examine additional variables as possible factors associated with the speed of metropolitan growth.

    The main objective of the Healthy Canada by Design CLASP Initiative in British Columbia (BC) was to develop, implement and evaluate a capacity-building project for health authorities. The desired outcomes of the project were as follows: 1) increased capacity of the participating health authorities to productively engage in land use and transportation planning processes; 2) new and sustained relationships or collaborations among the participating health authorities and among health authorities, local governments and other built environment stakeholders; and 3) indication of health authority influence and/or application of health evidence and tools in land use and transportation plans and policies. This project was designed to enhance the capacity of three regional health authorities, namely Fraser Health, Island Health and Vancouver Coastal Health, and their staff. These were considered the project's participants. The BC regions served by the three health authorities cover the urban, suburban and rural spectrum across relatively large and diverse geographic areas. The populations have broad ranges in socio-economic status, demographic profiles and cultural and political backgrounds. The Initiative provided the three health authorities with a consultant who had several years of experience working on land use and transportation planning. The consultant conducted situational assessments to understand the baseline knowledge and skill gaps, assets and objectives for built environment work for each of the participating health authorities. On the basis of this information, the consultant developed customized capacity-building work plans for each of the health authorities and assisted them with implementation. Capacity-building activities were as follows: researching health and built environment strategies, policies and evidence; transferring health evidence and promising policies and practices from other jurisdictions to local planning contexts; providing training and

  9. Suburbanization and sustainability in metropolitan Moscow.

    PubMed

    Mason, Robert J; Nigmatullina, Liliya

    2011-01-01

    Although Soviet-era urban-growth controls produced relatively sustainable metropolitan development patterns, low-density suburban sprawl has accelerated markedly in modern Russia. Distinctive features of Moscow's development history are its greenbelt, which dates from 1935 and is becoming increasingly fragmented, proliferation of satellite cities at the urban fringe, conversion of seasonal dachas into full-time residences, the very exclusive Rublevo Uspenskoe Highway development, and today's crippling traffic congestion. The recent economic crisis has slowed development and actually increased the supply of “economy-class” single-family homes, for which there is much pent-up desire but insufficient credit availability to meet the demand. A renewed commitment to sustainability's triple bottom line—environmental quality, equity, and economic prosperity—will require greater government transparency and fairness, stronger planning controls, and an expanded public transportation system.

    Southworth, Frank; Sonnenberg, Anthon

    2011-01-01

    The authors describe the development of a set of carbon dioxide emissions estimates for highway travel by automobile, truck, bus and other public transit vehicle movements within the nation s 100 largest metropolitan areas, in calendar year 2005. Considerable variability is found to exist across metropolitan areas when these greenhouse gas emissions are measured on a per capita and a per gross metropolitan product (GMP) basis. Least square regression modeling shows a relationship between emissions per capita and per GMP with truck traffic share, transit share, employment density, population dispersion within the metro area, and GMP per capita. As a result many of the nation s largest metropolitan areas tend to have lower CO2 emissions per capita and per GMP than smaller and more recently developed metro areas.

    Flood is one of the most significant natural hazards in Japan. The Tokyo metropolitan area has been affected by several large flood disasters. Therefore, investigating potential flood risk in Tokyo metropolitan area is important for development of adaptation strategy for future climate change. We aim to develop a method for evaluating flood risk in Tokyo Metropolitan area by considering effect of historical land use and land cover change, socio-economic change, and climatic change. Ministry of land, infrastructure, transport and tourism in Japan published 'Statistics of flood', which contains data for flood causes, number of damaged houses, area of wetted surface, and total amount of damage for each flood at small municipal level. By using these flood data, we estimated damage by inundation inside a levee for each prefecture based on a statistical method. On the basis of estimated damage, we developed flood risk curves in the Tokyo metropolitan area, representing relationship between damage and exceedance probability of flood for the period 1976-2008 for each prefecture. Based on the flood risk curve, we attempted evaluate potential flood risk in the Tokyo metropolitan area and clarify the cause for regional difference of flood risk. By analyzing flood risk curves, we found out regional differences of flood risk. We identified high flood risk in Tokyo and Saitama prefecture. On the other hand, flood risk was relatively low in Ibaraki and Chiba prefecture. We found that these regional differences of flood risk can be attributed to spatial distribution of entire property value and ratio of damaged housing units in each prefecture.We also attempted to evaluate influence of climate change on potential flood risk by considering variation of precipitation amount and precipitation intensity in the Tokyo metropolitan area. Results shows that we can evaluate potential impact of precipitation change on flood risk with high accuracy by using our methodology. Acknowledgments

  4. Latin America's supercity--the metropolitan area of Mexico City.

    PubMed

    1987-02-01

    Big and still growing, Mexico City and its environs is soon to be the world's largest metropolitan area. The lure of city amenties--jobs, health care, schooling, and cheap food--and the hope of a better life bring 1000 rural migrants to Mexico City every day. Between 1950 and 1980, Mexico City grew at an annual average rate of 5.4%. Mexico City is typical of Latin American supercities, holding an impressive portion of the nation's population and commanding the lion's share of the country's economic activities. It is primarily due to the rapid growth in the northern periphery of the municipalities that Mexico City is expected to grow into the world's largest metropolitan area by the year 2000. Given the high proportion of youth relative to the total population, it is not suprising that average household sizes in Mexico City are large. About 60% to 70% of all families have no access to the formal housing market; much of the urban expansion has occurred through the emergence of squatter communities. Water may indeed be the most serious of all of Mexico City's infrastructural problems. Other problems include: 1) the government cannot meet the demands for educational buildings and personnel; 2) in 1982, 10.3% of the metropolitan population lived in extreme poverty and an additional 22.6% were unable to satisfy their basic needs; and 3) transport is a central problem. Demographic sources for Mexico are discussed.

  10. Dynamism of Transportation and Land Use Interaction in Urban Context

    NASA Astrophysics Data System (ADS)

    Pandya, Rajesh J.; Katti, B. K.

    2012-10-01

    Transportation in urban areas is highly complex and the urban transport system is intricately linked with urban form and spatial structure. Urban transit is an important dimension of mobility, notably in high density areas. The spatial separation of human activities which creates the need for travel and goods transport is the underlying principle of transport analysis and forecasting. To understand the complex relationships between transportation and land use and to help the urban planning process, several models have been developed. Many theories, models are developed by different authors on land use and transportation interaction, which clearly indicate that change in land use transformation have a greater impact on transportation. Similarly, introducing new transportation facility or strengthening of existing transport facility makes an impact on the abutting land. In cities like Delhi, Navi Mumbai, Ahmedabad, introducing of new mass transport system or strengthening of existing transportation system had given greater impact on surrounding development. In this Paper the major theoretical approaches to explain the two-way interaction of land use and transport in metropolitan areas are summarized. The paper also reviews research on the two-way interaction between urban land use and transport, i.e. the location and mobility responses of private actors (households and firms, travelers) to changes in the urban land use and transport system at the urban regional level.

    A summary of tether transportation is given. Four steps were used over a period of time. First, theoretical engineering feasibility and technology requirements were determined. Then the survivors of that effort went into step two in the analysis of promising candidates. Those survivors went into the third phase which is engineering design and cost benefits. Survivors entered into the demonstration mission definition phase. Transportation studies have covered two kinds of deployments. First, steady state deployment was studied. Like the TSS, it's nearly vertical. It takes a long time to deploy and involves relatively high tether tension. Secondly, dynamic deployment was studied. Deployment started in an almost horizontal direction under a very shallow angle which allows a high deployment rate under very low tension. Momentum transfer here occurs by libration. Specific payloads were used to study tethered transportation benefits. Four transportation concepts were studied with regard to cost benefits. A tethered orbiter deboost from the space station, an OTV boost up from the Space Station, a science platform on a tether with a possible micro-g lab moving in between platform and station, and a tethered boost of payloads fromthe orbiter are the four concepts. These benefits are examined in detail.

    Sarbagita (Denpasar, Badung, Gianyar, and Tabanan) Metropolitan Area is one of seven metropolitan areas in Indonesia, located in the coastal region of Bali Island. Providing clean water in the coastal region is generally constrained by the limited sources of water. Besides, there is also disparity issue between the core and peri-urban area. The purpose of this study is to explore the conditions of water supply provision in Metropolitan Sarbagita in the context of coastal and peri-urban region. The methods of analysis used are descriptive and association analysis. The analysis shows that the location in the coastal area and peri-urban area does not affect the water supply provision for the case of daily safe water yet it does affect significantly in the specific context of drinking water source.

    The similarities and differences between areas inside and outside U.S. metropolitan areas were evaluated in terms of their commercial/industrial and government employment characteristics. The comparison focuses on the levels, shares, and composition of employment in the commercial/industrial and government sectors that represent potential classes of land mobile communications users. The major findings of the analysis are as follows: (1) non-metropolitan commercial/industrial user classes of land mobile communication services exist in significant numbers; (2) the compositions of non-metropolitan and metropolitan commercial/industrial user classes of land mobile communication services closely resemble each other; (3) non-metropolitan areas have significant levels of the government user classes that represent potential markets for land mobile communication services; and (4) non-metropolitan local governments have a significantly larger proportion of their employment in the primary user classes of private land mobile radio service than do metropolitan local governments.

    Casola, J.; Johanson, E.; Groth, P.; Snow, C.; Choate, A.

    2012-12-01

    Southeastern Pennsylvania Transportation Authority (SEPTA), with support from the Federal Transit Administration, has been investigating its agency's vulnerability to weather-related disruption and damages as a way to inform an overall adaptation strategy for climate variability and change. Exploiting daily rail service records maintained by SEPTA and observations from nearby weather stations, we have developed a methodology for quantifying the sensitivity of SEPTA's Manayunk/Norristown rail line to various weather events (e.g., snow storms, heat waves, heavy rainfall and flooding, tropical storms). For each type of event, sensitivity is equated to the frequency and extent of service disruptions associated with the event, and includes the identification of thresholds beyond which impacts are observed. In addition, we have estimated the monetary costs associated with repair and replacement of infrastructure following these events. Our results have facilitated discussions with SEPTA operational staff, who have outlined the institutional aspects of their preparation and response processes for these weather events. We envision the methodology as being useful for resource and infrastructure managers across the public and private sector, and potentially scalable to smaller or larger operations. There are several advantageous aspects of the method: 1) the quantification of sensitivity, and the coupling of that sensitivity to cost information, provides credible input to SEPTA decision-makers as they establish the priorities and level of investment associated with their adaptation actions for addressing extreme weather; 2) the method provides a conceptual foundation for estimating the magnitude, frequency, and costs of potential future impacts at a local scale, especially with regard to heat waves; 3) the sensitivity information serves as an excellent discussion tool, enabling further research and information gathering about institutional relationships and procedures.

    To estimate the prevalence of helmet use among motorcyclists in four metropolitan areas of Mexico (Guadalajara, León, Monterrey, and Mexico City). In October 2009, helmet use was observed in 26,046 drivers and 3,971 passengers of motorcycles at several zones of busy traffic. The data were analyzed by means of a hierarchical logistic regression model. The adjusted probabilities of helmet use strongly differed among the four metropolitan areas: Mexico City: 79-91%; León: 99%; Guadalajara: 54-58%; Monterrey: 73-95%. The probability is lower in passengers (Odds Ratio [OR]: 0.15, with a 95%-confidence interval [CI] of 0.14-0.17) and in drivers who carry some passenger (OR: 0.49; 95% CI: 0.45-0.54, as compared to drivers without passengers), and higher in users of motorcycles for commercial use (OR: 1.76; 95% CI: 1.59-1.96, as compared to private use). Moreover, an estimated 44% of the motorcyclists used a type of helmet that was not officially approved and/or they did not properly adjust the device. This study shows that in Guadalajara, Monterrey, and Mexico City it is appropriate to start initiatives to promote helmet use in motorcyclists, particularly for passengers and drivers who transport one or more passengers.

    OBJECTIVE To analyze the correlation between sociodemographic factors and working conditions of bus workers in a metropolitan area and violence against them. METHODS This cross-sectional study used a nonprobabilistic sample estimated according to the number of workers employed in bus companies located in three cities in the Belo Horizonte metropolitan region in 2012 (N = 17,470). Face-to-face interviews were conducted using a digital questionnaire. The factors associated with violence were analyzed in two stages using Poisson regression, according to each level. The magnitude of the association was evaluated using prevalence ratios with robust variance and a statistical significance of 5%, and 95% confidence intervals were obtained. RESULTS The study sample comprised 782 drivers and 691 fare collectors; 45.0% participants reported at least one act of violence in the workplace in the last 12 months, with passengers being predominantly responsible. The age of the bus workers was inversely associated with violence. Chronic diseases, sickness absenteeism, and working conditions were also associated with violence. CONCLUSIONS The findings on the correlation between violence and working conditions are essential for implementing prevention strategies by transportation service managers. PMID:25741657

    The Guadalajara metropolitan area, containing approximately three million inhabitants in the municipios of Guadalajara, Zapopan, Tlaquepaque, Tonala, and El Salto, has high rates of population growth due to in-migration, natural increase, and annexation of localities. The average annual rate of growth declined from 6.8% in the 1950s to 2.6% in the 1980s. Despite the decline, which can be considered an indicator of transition, the increase in absolute numbers resulting from a 2.6% rate of growth amounts to 78,000 new inhabitants each year. A change has occurred in recent decades in the migratory patterns and urban spatial distribution of Western Mexico. In-migration to the Guadalajara metropolitan zone has slowed in both absolute and relative terms. Growth of smaller and intermediate sized cities is now more rapid than is that of the metropolitan zone. Surveys in Guadalajara indicate that the proportion of in-migrants from urban areas has increased substantially. Despite the slowing pace of growth, the Guadalajara metropolitan area faces serious problems of housing, land use, transport, and urban infrastructure and services in general. Because of rapid growth and the preponderance of young people among the migrants, the problems are likely to persist for some time. Population projections suggest that 66,000 new jobs will be needed during 1990-95 and 57,000 during 1995-2000, assuming no significant increases in the proportion of women who work. An average of 2500 hectares of land will be needed every five years, nearly equivalent to the total area of the city in 1940. The number of daily trips on urban transit is projected to increase from 6 million at present to 7 million in 2005. The daily load of solid waste is expected to increase from 4000 to 5000 tons in 2005. The economic structure of the city is also changing. Commerce and small and medium-sized manufacturing enterprises have lost their primacy and large national and transnational manufacturing and commercial

    2011-12-01

    Flood is one of the most significant natural hazards in Japan. In particular, the Tokyo metropolitan area is highly vulnerable to flood, because densely populated area is located along mouth of major rivers. The Tokyo metropolitan area has been affected by several large flood disasters. We aim to evaluate potential flood risk in Tokyo Metropolitan area by considering effect of historical land use change, land cover change, socio-economic change, and climatic change. For this purpose, it is necessary to build up a consistent flood database system, which contains long-term consistent flood data for the past. Ministry of land, infrastructure, transport and tourism in Japan published "Statistics of flood", which contains data for flood causes, number of damaged houses, area of wetted surface, and total amount of damage for each flood at small municipal level. Based on these flood data documented in "Statistics of flood", we construct a flood database system for Tokyo metropolitan area for the period from 1961 to 2008 by using ArcGIS software. In this database, each flood record is linked to municipal polygons. By using this flood database, we can refer to a specific flood record for each year at small municipal level. We can also calculate total amount of damage for each flood cause such as innuduation inside the levee, over flow,innunduation by river water. First, we analyze long-term variations of flood risk in Tokyo metropolitan area based on this flood database. Then, we aim to evaluate influence of socio-economic and climatic change on flood risk variations by comparing flood variations in the past with rainfall data and socio-economic indicators. Finally, we construct a flood risk curve representing exceedance probability for total damage of flood by using past flood data. Based on the flood risk curve, we discuss potential vulnerability to flooding and risk of economic losses in Tokyo metropolitan area for climate change adaptation.

  5. Spatial variations in US poverty: beyond metropolitan and non-metropolitan.

    Wang, Man; Kleit, Rachel Garshick; Cover, Jane; Fowler, Christopher S

    2012-01-01

    Because poverty in rural and urban areas of the US often has different causes, correlates and solutions, effective anti-poverty policies depend on a thorough understanding of the ruralness or urbanness of specific places. This paper compares several widely used classification schemes and the varying magnitudes of poverty that they reveal in the US. The commonly used ‘metropolitan/non-metropolitan’ distinction obscures important socioeconomic differences among metropolitan areas, making our understanding of the geography of poverty imprecise. Given the number and concentration of poor people living in mixed-rural and rural counties in metropolitan regions, researchers and policy-makers need to pay more nuanced attention to the opportunities and constraints such individuals face. A cross-classification of the Office of Management and Budget’s metro system with a nuanced RUDC scheme is the most effective for revealing the geographical complexities of poverty within metropolitan areas.

    Improving the performance of electronic and optoelectronic components has enabled the investigation of transmitting optical channels with data rates greater than 40 Gb/s, over infrastructures that were initially supporting 10 Gb/s transport. However, for transporting high capacity channels, over long distances, considerable signal processing is necessary, with current emphasis being on digital techniques. Meanwhile in the context of optical networking where spectrally adjacent channels may cross different routes to interconnect the same source destination nodes, adaptive transmission systems become vital. This paper will suggest, compare and develop the necessary transponder technologies that enable transportation of 40 Gb/s channels over deployed Metropolitan Area optical Networks (MAN) infrastructure with emphasis on the interplay between realistic performance, feasibility and complexity/cost. Specifically it will investigate utilizing deployed optical infrastructure for transporting 40 Gb/s DQPSK channels in conjunction with various high performance, low complexity electronic equalizers that can compensate the corresponding linear impairment enhancement that accompanies this upgrade, namely Chromatic Dispersion and Polarization Mode Dispersion while they can be implemented in a single FPGA. It is shown that resource constraint performance evaluation is vital and the exact technology choice is related to the deployed infrastructure.

  3. Evaluation of WRF-CHEM Model: A case study of Air Pollution Episode in Istanbul Metropolitan

    NASA Astrophysics Data System (ADS)

    2014-05-01

    Istanbul is the largest city in Europe with a population of about 14 million and nearly 3.2 million registered vehicles. Considering that the city is at the junction of major transportation routes on both land and sea, emissions from all motor vehicles operating in the city and those that are in transit is the major source of pollution. The natural gas is used as the major heat source and the impact of other heating sources on the pollution episodes is not clearly known. During 19-29 December 2013 İstanbul metropolitan area experienced a severe PM10 episode with average episode concentration of 127µgm-3 . The episode was associated with a high pressure system with center pressure of 1030 mb residing over Balkans and north of Black Sea and thereby influencing Istanbul. We carried out simulations using the Weather Research and Forecasting model with Chemistry (WRF-CHEM) v3.5 to examine the meteorological conditions and to produce estimates of PM10 over Istanbul for 17-31 December 2013. The three nested domains was setup using 18, 6 and 2 km horizontal grid spacing with (90x90), (115x115) and (130x130) grid points in 1st, 2nd and 3rd domains, respectively. The each domain was run using one way nesting option after preparing the results from the mother domain as an input to subsequent inner domain. 34 vertical levels were used with the lowest layer depth of 15 m above the surface and extending to 15 km at the model top. The model was configured using the model options after many tests to find optimal model parameters and was initialized using global emissions data available publicly. The local emissions database is still in works and is not available to use in the model instead of global data. The estimated PM10 concentrations were compared against the observed conditions. This work shows the first attempt of using WRF-CHEM in Turkey to estimate the pollutant concentrations instead of using other air pollution models such as WRF/CMAQ combination. At the time of

    2015-01-01

    Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems of coupling different modes and we report in this paper an empirical analysis of the coupling between the street network and the subway for the two large metropolitan areas of London and New York. We observe a similar behaviour for network quantities related to quickest paths suggesting the existence of generic mechanisms operating beyond the local peculiarities of the specific cities studied. An analysis of the betweenness centrality distribution shows that the introduction of underground networks operate as a decentralizing force creating congestion in places located at the end of underground lines. Also, we find that increasing the speed of subways is not always beneficial and may lead to unwanted uneven spatial distributions of accessibility. In fact, for London—but not for New York—there is an optimal subway speed in terms of global congestion. These results show that it is crucial to consider the full, multimodal, multilayer network aspects of transportation systems in order to understand the behaviour of cities and to avoid possible negative side-effects of urban planning decisions.

    1990-06-01

    Florida's Orlando metropolitan area, which has a population measuring 1 million, is among the fastest growing areas in the nation. The city's weather and popular attractions draw 9 to 10 million tourists annually, half of them arriving in their own cars. Add to this the 1.1 million automobiles already on the streets, and the traffic problems become a nightmare. The Orlando metropolitan area has approximately 550 operational traffic signals, with an increasing number of new signals added each year to control the city's expanding growth. A central, computerized signal system has been conceived as one of the solutions necessary to cope with this tremendous traffic growth. The system is flexible, expandable, and capable of meeting future technical challenges. This article describes the steps that led to the feasibility study, design, and implementation of the Orlando area computerized signal system.

  8. Racial Diversity and Change in Metropolitan Neighborhoods*

    PubMed Central

    Farrell, Chad R.; Lee, Barrett A.

    2011-01-01

    This study investigates the changing racial diversity and structure of metropolitan neighborhoods. We consider three alternative perspectives about localized racial change: that neighborhoods are bifurcating along a white/nonwhite color line, fragmenting into homogeneous enclaves, or integrating white, black, Latino, and Asian residents into diverse residential environments. To assess hypotheses drawn from these perspectives, we develop a hybrid methodology (incorporating the entropy index and majority-rule criteria) that offers advantages over previous typological efforts. Our analysis of 1990–2000 census tract data for the 100 largest U.S. metropolitan areas finds that most neighborhoods are becoming more diverse and that members of all groups have experienced increasing exposure to neighborhood diversity. However, white populations tend to diminish rapidly in the presence of multiple minority groups and there has been concomitant white growth in low-diversity neighborhoods. Latino population dynamics have emerged as a primary force driving neighborhood change in a multi-group context. PMID:21691412

    Authoring tools that are accessible and that enable authors to produce accessible Web content play a critical role in web accessibility. Widespread use of authoring tools that comply to the W3C Authoring Tool Accessibility Guidelines (ATAG) would ensure that even authors who are neither knowledgeable about nor particularly motivated to produce accessible content do so by default. The principles and techniques of ATAG are discussed. Some examples of accessible authoring tools are described including authoring tool content management components such as TinyMCE. Considerations for creating an accessible collaborative environment are also covered. As part of providing accessible content, the debate between system-based personal optimization and one universally accessible site configuration is presented. The issues and potential solutions to address the accessibility crisis presented by the advent of rich internet applications are outlined. This challenge must be met to ensure that a large segment of the population is able to participate in the move toward the web as a two-way communication mechanism.

  10. Neighborhood Diversity, Metropolitan Constraints, and Household Migration

    Crowder, Kyle; Pais, Jeremy; South, Scott J.

    2012-01-01

    Focusing on micro-level processes of residential segregation, this analysis combines data from the Panel Study of Income Dynamics with contextual information from three censuses and several other sources to examine patterns of residential mobility between neighborhoods populated by different combinations of racial and ethnic groups. We find that despite the emergence of multiethnic neighborhoods, stratified mobility dynamics continue to dominate, with relatively few black or white households moving into neighborhoods that could be considered multiethnic. However, we also find that the tendency for white and black households to move between neighborhoods dominated by their own group varies significantly across metropolitan areas. Black and white households’ mobility into more integrated neighborhoods is shaped substantially by demographic, economic, political, and spatial features of the broader metropolitan area. Metropolitan-area racial composition, the stock of new housing, residential separation of black and white households, poverty rates, and functional specialization emerge as particularly important predictors. These macro-level effects reflect opportunities for intergroup residential contact as well as structural forces that maintain residential segregation. PMID:22753955

    This article addresses an aspect of racial residential segregation that has been largely ignored in prior work: the issue of geographic scale. In some metropolitan areas, racial groups are segregated over large regions, with predominately white regions, predominately black regions, and so on, whereas in other areas, the separation of racial groups occurs over much shorter distances. Here we develop an approach—featuring the segregation profile and the corresponding macro/micro segregation ratio—that offers a scale-sensitive alternative to standard methodological practice for describing segregation. Using this approach, we measure and describe the geographic scale of racial segregation in the 40 largest U.S. metropolitan areas in 2000. We find considerable heterogeneity in the geographic scale of segregation patterns across both metropolitan areas and racial groups, a heterogeneity that is not evident using conventional “aspatial” segregation measures. Moreover, because the geographic scale of segregation is only modestly correlated with the level of segregation in our sample, we argue that geographic scale represents a distinct dimension of residential segregation. We conclude with a brief discussion of the implications of our findings for investigating the patterns, causes, and consequences of residential segregation at different geographic scales.

    1985-02-01

    Brazil's capital city, Rio de Janeiro, has been called Latin America's slum capital, and is slowly losing its political position to Brasilia and its cultural and economic leadership to Sao Paolo. Rio's metropolitan area includes 14 municipalities and had a population of 9.64 million in 1984, making it Latin America's 4th largest and the world's 14th largest metropolitan area. The 452-square mile central city contains 5.35 million people. Projections predict that Rio will be the world's 9th largest city in the year 2000, with a population of 13.3 million. Rio encompasses sharp social and economic contrasts; population density varies from 30,686 to 124 people per square mile and per capita municipal budgets range from $100 to $12.50. Like most metropolitan areas, Rio's suburbs show its greatest growth. The peripheral municipalities which held only 24% of the population in 1940, now have about 45%. Low land prices and government housing attact poor families to these areas which tend to be economically sluggish. Rio's fertility rate (2.8%) is the lowest in Brazil (4.2%) and life expectancy is somewhat higher than the national average. Low fertility and declining migration result in small households and increasing age structure. 2.2 million households, with 3.8 persons on an average, and 1.3 million households, with 3.6 persons, inhabited the metropolitan area and its municipality, respectively.

  17. Employment income of immigrants in metropolitan areas of Canada, 1980.

    Verma, R B; Basavarajappa, K G

    1989-09-01

    This paper examines the economic achievements of immigrant groups and compares them with those of the Canadian-born population. Employment income in this study is income for members of the labor force who worked 40 weeks or more, full time, during 1980. The information is from the 1981 Census. The 15 birthplace groups considered in this study are classified into 2 major groups: those from traditional sources and those from non-traditional or new sources. Traditional sources are the US, UK, and Europe. The new sources are Africa, Asia, South and Central America, the Caribbean, and Oceania. More than 1/2 of the immigrants from traditional sources arrived before 1960, whereas more than 1/2 of immigrants from new sources arrived after 1970. The analysis is only for those areas called Census Metropolitan Areas. Results of analysis show that 1) immigrant men and women in metropolitan areas earned 1.9% and 5.9% respectively less than their Canadian-born counterparts; 2) when differences in age and educational attainment were considered, incomes of immigrant men and women were about 7.5% below those of their Canadian-born counterparts; 3) the new immigrant groups earned far less than those of the Canadian-born counterparts; 4) traditional-source immigrants' incomes were equal to or slightly higher than Canadians'; and 5) as length of residence increases, most immigrant groups improve their relative economic position and achieve incomes comparable to Canadians'. The authors discuss the economic adaptation of immigrants in the light of various models: assimilation, Marxist class conflict, ethnic stratification and segmentation, structural pluralism, and structural change. No theory can be applied to the economic adaptation of all types of immigrants. Finally, refugees and sponsored relatives, who are not admitted on the basis of education and occupational need, are likely to have more difficulties than independent immigrants.

    This report introduces and discusses the present state of the helicopter emergency medical services (HEMS) in the metropolitan area of South Korea. The data of patients transported by HEMS from April 2007 to June 2009 were provided by Seoul Metropolitan Fire and Disaster Management Department. The data of patients subsequently transported to Korea University Guro Hospital were analyzed. During the study period, 725 emergency rescue calls were dispatched and 703 patients were rescued, of which 562 patients were judged by an emergency medical technician to be in a nonemergent condition and were referred to ground emergency medical services and 141 patients were judged as having an emergent situation and were directly transported to a nearby hospital. The data of patients who were transported to Korea University Guro Hospital by HEMS were as follows. The mean age was 51.7±12.1 years; 75.6% were male patients; 28 patients (68.3%) were traumatically injured; the mean of the injury severity score was 13.5±14.7, and 13 patients (46.4%) had an injury severity score of more than 15. No procedures other than basic life support were performed by the emergency medical technicians during transport. The role of HEMS in South Korea is limited to transporting injured patients from locations that cannot be approached by ground emergency medical services. Even though HEMS is essential considering the local mountainous geography of Seoul, Korea, overutilization of HEMS is still suspected in the metropolitan area.

    The bill was introduced into the US House of Representatives on June 7, 1991 to amend the Solid Waste Disposal Act. This legislation authorizes states to regulate the interstate transportation of solid waste, and to authorize a private right of action to enforce any such regulation. The key feature on this bill focuses on authorizing states to regulate solid waste in interstate commerce. In addition, any regulation is required to include certain civil and criminal penalties. This act requires that a civil penalty of a fine not to exceed $1,000,000 and a criminal penalty of a fine not to exceed $1,000,000, or imprisonment for not more than 1 year, or both.

    1997-12-31

    The introduction of several reformulated gasolines into the Mexico City Metropolitan Zone (MCMZ) in the middle 1986 is an example of using fuel composition to improve, in theory, the air quality. However, although these changes have resulted in an important reduction of lead airborne concentrations, a worsened situation has been created. Ozone levels in the atmosphere MCMZ have presented a sudden rise since the introduction of the first reformulated gasoline, reaching in the 1990`s an annual average of 1,700 exceedances to the Mexican Ozone Air Quality Standard (0.11 ppm not to be exceeded 1 hr. a day one day a year). The authors examine the tendency on ozone air quality in MCMZ in relation with the changes in gasoline composition since 1986. The authors also discuss the importance to perform an air quality impact analysis before the introduction of reformulated gasolines in countries where the local economy do not allow to change the old car fleet not fitted with exhaust treatment devices.

    This proposal outlines an action plan for risk management in the Delaware Valley Metropolitan Region. This plan is consistent with the goals for strengthening homeland security announced by President Bush, and is designed to complement efforts currently under development by Pennsylvania Emergency Management Agency and Department of Health. This plan proposes the formation of a Delaware Valley Risk Management Consortium, representing the critical disciplines and organizations related to risk assessment and management. This group would have membership from academic institutions, government agencies, industry, and nonprofit organizations. This Consortium would develop a systemic scope of work with the appropriate recommendations for technology acquisition, development and integration with risk management policies and procedures. This scope of work would include the development of two related information systems for the Delaware Valley Region. The first would be a comprehensive 'health monitoring' system to assess the continuity of operations, which would use integrated remote sensing and imaging, information gathering, communication, computation, and, information processing and management over wide-area networks covering the entire metropolitan area. The second would use real-time information from the health monitoring system to support interactive communication, search and information exchange needed to coordinate action among the relevant agencies to mitigate risk, respond to hazards and manage its resources efficiently and effectively.

    Airport congestion at primary airports in major metropolitan areas was analyzed in a report prepared by the Transportation Research Board (TRB) in 1990. Taking the top twenty-three most congested airports from this study, a questionnaire was prepared and sent to the metropolitan planning organizations (MPOs) for twenty of the twenty-three metropolitan areas represented in the TRB study, The questionnaire focused on the role of the MPOs in planning for new primary airports in the United States, including questions about the status of the most recent MPO airport system plan, whether or not the latest plan recommends a new primary airport, and whether or not any other entities in the MPO areas are recommending new primary airports. The results indicated that 44.4 percent of the eighteen respondent MPOs have airport system plans that are five years old or older. Also, only two of the respondent MPOs have recommended a new primary airport in their latest regional airport system plan and only one of these two is a common recommendation in the Federal Aviation Administration's National Plan of Integrated Airport System.

  4. The coastal metropolitan corn trade in later seventeenth-century England.

    PubMed

    Hipkin, Stephen

    2012-01-01

    Exploiting hitherto unexamined London port book data, this article shows that during the last quarter of the seventeenth century the coastal metropolitan corn import trade was twice the size that historians relying on the work of Gras have assumed it to have been. More significantly, it demonstrates that Gras's failure to examine the capital's grain trade other than in terms of aggregate corn imports has disguised the nature and extent of its contribution to the development of the London economy. By the 1680s, the coastal trade comprised two distinct strands of roughly equal size: one providing food and drink for the London population, the other fuelling the overland trade of the capital. It is argued that the former was unnecessary for the provision of the city other than in barren years, but that the latter may have been indispensable for the development of the overland transport infrastructure of the metropolitan region at the height of the late seventeenth-century commercial revolution. Thanks largely to the agency of southern English mariners commanding large coasters, London's demand for fodder crops after the mid-1670s drew most of the coast stretching from Berwick to Whitehaven into the orbit of the metropolitan corn market.

    2013-05-01

    This research explored the link between coronary heart disease (CHD) prevalence and metropolitan-area level occupational structure among 137 metropolitan/micropolitan statistical areas (MMSA) in the United States. Using data from the 2006-2008 Behavioral Risk Factor Surveillance System and 2007 County Business Patterns, logistic mixed models were developed to estimate CHD prevalence between MMSAs controlling for individual-level socioeconomic characteristics and various types of occupational structure. Results showed that CHD prevalence was lower in MMSAs where their economy was dominated by 'tourism and resort' and 'the quaternary sector' and higher in MMSAs dominated by 'manufacturing', 'transportation and warehousing', and 'mining'. MMSA-level effects on CHD were found in 'tourism and resort' and 'the quaternary sector' having lower risk and 'mining' having higher risk of CHD. Although these effects prevailed in many MMSAs, some MMSAs did not fit into these effects. Additional analysis indicated a possible link between metropolitan population loss and higher CHD prevalence especially in the coal mining region of the Appalachian Mountains.

    This work demonstrates that road traffic simulation of entire metropolitan areas is possible with reconfigurable supercomputing that combines 64-bit microprocessors and FPGAs in a high bandwidth, low latency interconnect. Previously, traffic simulation on FPGAs was limited to very short road segments or required a very large number of FPGAs. Our data streaming approach overcomes scaling issues associated with direct implementations and still allows for high-level parallelism by dividing the data sets between hardware and software across the reconfigurable supercomputer. Using one FPGA on the Cray XD1 supercomputer, we are able to achieve a 34.4 x speed up over the AMD microprocessor. System integration issues must be optimized to exploit this speedup in the overall simulation.

  8. Substance use for insomnia in Metropolitan Detroit.

    2002-07-01

    People with insomnia are not typically treated medically for their insomnia. Studies have reported approximately 30% of insomniacs self-medicate with alcohol or over-the-counter (OTC) medications. This study was done to identify determinants and risks of different insomnia therapeutics. A random-digit-dial, computer-assisted survey of a representative sample of adults in Metropolitan Detroit, aged 18-65 years, is being conducted. A sample of all respondents over an 18-month period was collected (n=1324) with a 68% response rate. Exclusive past-year use of alcohol for sleep was reported by 10% (n=132), prescription medications by 8% (n=108), and OTC medications by 10% (n=135). Five percent used both alcohol and sleep medications. The three exclusive-use groups formed the comparison groups of the study. The prescription drug group used medications for more consecutive nights and for more total nights than the alcohol and OTC users. Alcohol users were predominantly male, while OTC and prescription drug users were predominantly female. Alcohol users were more likely to be single than the others, and prescription drug users were older than the others. Prescription drug users had more severe insomnia and had greater disability, neuroticism, and daytime fatigue than the others. In contrast, the alcohol users had greater daytime sleepiness than the others. In Metropolitan Detroit, insomniacs receiving medical treatment have more severe insomnia and greater disability than those who self-treat. However, while the insomnia of those self-treating is less severe, it is still associated with some risks.

  9. Retaining nurses in metropolitan areas: insights from senior nurse and human resource managers.

    2016-11-01

    To investigate the views of senior nurse and human resource managers of strategies to retain hospital nurses in a metropolitan area. Against a global shortage, retaining nurses is a management imperative for the quality of hospital services. Semi-structured interviews, thematically analysed. Metropolitan areas have many health organisations in geographical proximity, offering nurses choices in employer and employment. Senior nurse and human resource managers recognised the complexity of factors influencing nurse turnover, including those that 'pulled' nurses out of their jobs to other posts and factors that 'pushed' nurses to leave. Four themes emerged in retaining nurses: strategy and leadership, including analysis of workforce and leavers' data, remuneration, the type of nursing work and career development and the immediate work environment. In contexts where multiple organisations compete for nurses, addressing retention through strategic leadership is likely to be important in paying due attention and apportioning resources to effective strategies. Aside from good human resource management practices for all, strategies tailored to different segments of the nursing workforce are likely to be important. This metropolitan study suggests attention should be paid to strategies that address remuneration, progressing nursing careers and the immediate work environment. © 2016 The Authors Journal of Nursing Management Published by John Wiley & Sons Ltd.

  10. Tuberculosis Containment among the Homeless in Metropolitan Jackson, Mississippi.

    Preventing tuberculosis among the homeless has emerged as an especially difficult challenge. We assessed a 2008-2009 tuberculosis (TB) outbreak ad subsequent prevention strategies among homeless persons in metropolitan Jackson, Hinds County, Mississippi. We compared data about cases and subclinical TB infections (LTBI) among homeless persons during the outbreak and post-outbreak years, interviewed involved homeless persons, compiled observations from visits to Jackson homeless shelters and conducted literature reviews on homelessness and infectious diseases. We reviewed homeless shelter TB prevention methods adopted by other municipalities, guidelines developed by the Centers for Disease Control and Prevention (CDC), and recommendations from other official and ad hoc groups and considered their applicability to metropolitan Jackson. The Mississippi State Department of Health TB Program assisted by the CDC and other agencies, contained the Jackson-area outbreak by the end of 2009 as reflected by progressively lower TB rates among homeless persons thereafter. However, some follow-up activities and enforcement of shelter preventive measures have not been consistently maintained. Resources to prevent further outbreaks continue to be inadequate, and over-reliance on private organizations has continued. In the process, appreciation of the dynamic interaction enhancing TB risk among the homeless and incarcerated persons has emerged. Major outbreak contributors were lack of periodic TB screening among homeless shelter clients, preventive treatment compliance and follow-up difficulties among those with subclinical tuberculosis infections, interrupted preventive measures among infected persons incarcerated in local correctional facilities who disproportionately re-join Jackson's homeless community when released, inadequate attention to shelter environmental preventive strategies such as ultraviolet light germicidal irradiators and proper air-exchange/ventilation, costs of

    OBJECTIVES: This study tested the hypothesis that the degree to which local government is metropolitanized is associated with mortality rates for African Americans and with residential segregation, which has itself previously been shown to be positively associated with mortality among African Americans. METHODS: One hundred fourteen US standard metropolitan statistical areas were examined. The primary dependent variable was the age-adjusted, race- and sex-specific all-cause mortality rate, averaged for 1990 and 1991. The 2 primary independent variables were residential segregation, as measured by the index of dissimilarity, and metropolitanization of government, as measured by the central city's elasticity score. RESULTS: Mortality rates for male and female African Americans were lower in metropolitan statistical areas with more metropolitanized local governments and lower levels of residential segregation. Mortality for male and female Whites was not associated in either direction with residential segregation. White male mortality showed no association with level of metropolitanization, but lower White female mortality rates were associated with less metropolitanization. CONCLUSIONS: This study suggests the need for further research into whether policy changes in areas not traditionally thought of as "health policy" areas can improve the health of urban minorities.

    Context This article explores the relationship between metropolitan fragmentation, as defined by the total number of governmental units within a metropolitan statistical area (local municipalities, special service districts, and school districts), and racial disparities in mortality among blacks and whites in the 1990s. The presence of numerous governmental jurisdictions in large metropolitan areas in the United States can shape the geography of opportunity, with adverse consequences for health. Methods We conducted a regression analysis using U.S. Census of Government data and Compressed Mortality File data for the country's largest 171 metropolitan statistical areas. Findings We found a link between increased metropolitan area fragmentation and greater racial differences in mortality between blacks and whites for both children and working-age adults. Although increasing fragmentation is associated with a higher mortality rate for blacks, it is not associated with a higher mortality rate for whites. These findings suggest that research is needed to understand how governance can positively or negatively influence a population's health and create conditions that generate or exacerbate health disparities. Conclusions We need to understand the extent to which metropolitan fragmentation contributes to racial segregation, whether racism contributes to both, and the role of poverty and antipoverty policies in reducing or exacerbating the consequences of metropolitan fragmentation. The exact pathways by which metropolitan fragmentation contributes to differences between blacks’ and whites’ mortality rates are unknown. Uncovering how institutions influence the social, economic, and environmental conditions, which in turn contribute to the current racial and ethnic health disparities in the largest metropolitan areas, is key. Understanding these “upstream” determinants of a population's health and the disparities in health between subgroups in the overall population

    TRANSIMS version 3.1 is an integrated set of analytical and simulation models and supporting databases. The system is designed to create a virtual metropolitan region with representation of each of the region’s individuals, their activities and the transportation infrastructure they use. TRANSIMS puts into practice a new, disaggregate approach to travel demand modeling using agent-based micro-simulation technology. TRANSIMS methodology creates a virtual metropolitan region with representation of the transportation infrastructure and the population, at the level of households and individual travelers. Trips a planned to satisfy the population’s activity pattems at the individual traveler level. TRANSIMS then simulates the movement of travelers and vehicles across the transportation network using multiple modes, including car, transit, bike and walk, on a second-by-second basis. Metropolitan planners must plan growth of their cities according to the stringent transportation system planning requirements of the Interniodal Surface Transportation Efficiency Act of 1991, the Clean Air Act Amendments of 1990 and other similar laws and regulations. These require each state and its metropotitan regions to work together to develop short and long term transportation improvement plans. The plans must (1) estimate the future transportation needs for travelers and goods movements, (2) evaluate ways to manage and reduce congestion, (3) examine the effectiveness of building new roads and transit systems, and (4) limit the environmental impact of the various strategies. The needed consistent and accurate transportation improvement plans require an analytical capability that properly accounts for travel demand, human behavior, traffic and transit operations, major investments, and environmental effects. Other existing planning tools use aggregated information and representative behavior to predict average response and average use of transportation facilities. They do not account

    Dhaka Metropolitan City (including Dhaka and five adjacent municipal areas) is one of the fastest developing urban regions in the world. Densely build-up areas in the developed metropolitan area of Dhaka City are subject to extensive restructuring as common six- or lower storied buildings are replaced by higher and heavier constructions. Additional stories are built on existing houses, frequently exceeding the allowable bearing pressure on the subsoil as supported by the foundations. In turn, newly developing city areas are projected in marshy terrains modified by extensive, largely unengineered landfills. In most areas, these terrains bear unfavorable building ground conditions within 30 meters. Within a collaborative technical cooperation project between Bangladesh and Germany, BGR supports GSB in the provision of geo-information for the Capital Development Authority (RAJUK). For general urban planning, RAJUK successively develops a detailed area plan (DAP) at scale 1 : 50000 for the whole Dhaka Metropolitan City area (approx. 1700 km2). Geo-information have not been considered in the present DAP. Within the project, geospatial information in form of a geomorphic map, a digital terrain model and a 3-D subsurface model covering the whole city area have been generated at a scale of 1 : 50000. An extensive engineering geological data base consisting of more than 2200 borehole data with associated Standard Penetration Testing (SPT) and lab data has been compiled. With the field testing (SPT) and engineering geological lab data, the 3-D subsurface model can be parameterized to derive important spatial subsurface information for urban planning like bearing capacity evaluations for different foundation designs or soil liquefaction potential assessments for specific earthquake scenarios. In conjunction with inundation potential evaluations for different flooding scenarios, comprehensive building ground suitability information can be derived to support risk

  4. Metropolitan migration and population growth in selected developing countries.

    PubMed

    1983-01-01

    The purpose of this article is to estimate the components of metropolitan population growth in selected developing countries during 1960-1970 period. The study examines population growth in 26 cities: 5 are in Africa, 8 in Asia, and 13 in Latin America, using data from national census publications. These cities in general are the political capitals of their countries, but some additional large cities were selected in Brazil, Mexico, and South Africa. All cities, at the beginning of the 1960-1970 decade had over 500,000 population; Accra, the only exception, reached this population level during the 1960s. Some cities had over 4 million residents in 1970. Net migration contributed about 37% to total metropolitan population growth; the remainder of the growth is attributable to natural increase. Migration has a much stronger impact on metropolitan growth than suggested by the above figure: 1) Several metropolitan areas, for various reasons, are unlikely to receive many migrants; without those cities, the share of metropolitan growth from net migration is 44%. 2) Estimates of the natural increase of migrants after their arrival in the metropolitan areas, when added to migration itself, changes the total contribution of migration to 49% in some metropolitan areas. 3) Even where net migration contributes a smaller proportion to metropolitan growth than natural increase, the rates of net migration are generally high and should be viewed in the context of rapid metropolitan population growth from natural increase alone. Finally, the paper also compares the components of metropolitan growth with the components of growth in the remaining urban areas. The results show that the metropolitan areas, in general, grow faster than the remaining urban areas, and that this more rapid growth is mostly due to a higher rate of net migration. Given the significance of migration for metropolitan growth, further investigations of the effects of these migration streams, particularly with

    Mental illness represents an important public health problem. Local-level data concerning mental illness in different populations (e.g., socio-demographics and residence--metropolitan/urban/rural) provides the evidence-base for public health authorities to plan, implement and evaluate control programs. This paper describes prevalence and covariates of psychiatric conditions in Georgia populations in three defined geographic areas. Data came from the Georgia population-based random-digit-dialing study investigating unwellness and chronic fatigue syndrome (CFS) in Georgia populations of three defined geographic areas (metropolitan, urban, and rural). Respondents were screened for symptoms of fatigue, sleep, cognition, and pain at household screening interviews, and a randomly selected sample completed detailed individual phone interviews. Based on the detailed phone interviews, we conducted one-day clinical evaluations of 292 detailed interview participants classified as unwell with a probable CFS (i.e. CFS-like; a functional somatic syndrome), 268 classified as other unwell, and 223 well (matched to CFS-like). Clinical evaluation included psychiatric classification by means of the Structured Clinical Interview for DSM (SCID). To derive prevalence estimates we used sample weighting to account for the complexity of the multistage sampling design. We used 2- and 3-way table analyses to examine socio-demographic and urbanicity specific associations and multiple logistic regression to calculate adjusted odds ratios. Anxiety and mood disorders were the most common psychiatric conditions. Nineteen percent of participants suffered a current anxiety disorder, 18% a mood disorder and 10% had two or more conditions. There was a significant linear trend in occurrence of anxiety or mood disorders from well to CFS-like. The most common anxiety disorders were post-traumatic stress disorder (PTSD) (6.6%) and generalized anxiety disorder (GAD) (5.8%). Logistic regression showed that

    This study describes a system for the automatic recording of positioning data for public transport vehicles used on roads. With the data provided by this system, transportation-regulatory authorities can control, verify and improve the routes that vehicles use, while also providing new data to improve the representation of the transportation network and providing new services in the context of intelligent metropolitan areas. The system is executed autonomously in the vehicles, by recording their massive positioning data and transferring them to remote data banks for subsequent processing. To illustrate the utility of the system, we present a case of application that consists of identifying the points at which vehicles stop systematically, which may be points of scheduled stops or points at which traffic signals or road topology force the vehicle to stop. This identification is performed using pattern recognition techniques. The system has been applied under real operating conditions, providing the results discussed in the present study.

    Background The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. Methods From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. Results Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7%) of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. Conclusion Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

  12. Source apportionment of PM2.5 for supporting control strategies in the Monterrey Metropolitan Area, Mexico.

    2016-06-01

    The Monterrey Metropolitan Area (MMA) in Northeast Mexico has shown high PM2.5 concentrations since 2003. The data shows that the annual average concentration exceeds from 2 to 3 times the Mexican PM2.5 annual air quality standard of 12 µg/m(3). In a previous work we studied the chemical characterization of PM2.5 in two sites of the MMA during the winter season. Among the most important components we found ammonium sulfate and nitrate, elemental and organic carbon, and crustal matter. In this work we present the results of a second chemical characterization study performed during the summer time and the application of the chemical mass balance (CMB) model to determine the source apportionment of air pollutants in the region. The chemical analysis results show that the chemical composition of PM2.5 is similar in both sites and periods of the year. The results of the chemical analysis and the CMB model show that industrial, traffic, and combustion activities in the area are the major sources of primary PM2.5 and precursor gases of secondary inorganic and organic aerosol (SO2, NOx, NH3, and volatile organic compounds [VOCs]). We also found that black carbon and organic carbon are important components of PM2.5 in the MMA. These results are consistent with the MMA emission inventory that reports as major sources of particles and SO2 a refinery and fuel combustion, as well as nitrogen oxides and ammonium from transportation and industrial activities in the MMA and ammonium form agricultural activities in the state. The results of this work are important to identify and support effective actions to reduce direct emissions of PM2.5 and its precursor gases to improve air quality in the MMA. The Monterrey Metropolitan Area (MMA) has been classified as the most air-polluted area in Mexico by the World Health Organization (WHO). Effective actions need to be taken to control primary sources of PM2.5 and its precursors, reducing health risks on the population exposed and their

    This study addresses the recent climatology of hail occurrence in the Greater Metropolitan Severe Thunderstorm Warning Area (GMSTWA) of New South Wales, Australia, which is a sprawling suburban area, with a population of nearly 4.7 million and one of Australia's largest metropolis. The main objective is to highlight the recent temporal-spatial fluctuations of hailstone frequencies and magnitudes for each of recognized and vastly inhabited Local Government Areas (LGAs). The relevant hail event data from 1989 to 2013 were initially derived from the severe storm archive of Australian Bureau of Meteorology. A climatologically oriented GIS technique was applied in the examining and mapping procedure of all hail events and hail days reported throughout the study area. By applying a specific criterion, all severe hails (defined as 2 cm or more in diameter) were cautiously selected and then imported into the ArcGIS software for relevant analysis. Appropriate data layers were stored in a unique database to allow logical integration of the data directly into some geoprocessing functions, mainly for querying, analyzing and mapping purposes in a model-builder setting. The database includes 357 hailstones with sizes 2-11 cm and occurred in 169 hail days across the region during the past 25 years. The models have established that hailstones are neither temporally nor spatially uniform in magnitude throughout the study area. Temporal analysis indicated that most of hail events occurred predominately in the afternoons with peak time of 1-5 p.m. EST. They were particularly common in spring and summer, and reached maximum frequency in November and December. There was an average of 14.3 events each year, but a significant decreasing trend in terms of hail frequency and associated magnitude in the recent years has been identified. In turn, spatial models also established three main distribution patterns over the study area, which include the Sydney Metropolitan, coastal and pronounced

    The safety of magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is the responsibility of the Federal Railroad Administration (FRA). Plans for near future US applications include maglev projects (e.g. in Orlando, FL and Pittsburgh, PA) and high speed rail (the French Train a Grande Vitesse (TGV) in the Texas Triangle). Concerns exist regarding the potential safety, environmental and health effects on the public and on transportation workers due to electrification along new or existing rail corridors, and to maglev and high speed rail operations. Therefore, the characterization of electric and magnetic fields (EMF) produced by both steady (dc) and alternating currents (ac) at power frequency (50 Hz in Europe and 60 Hz in the U.S.) and above, in the Extreme Low Frequency (ELF) range (3-3000 Hz) is of interest. A portable magnetic field monitoring system (augmented to include an electric fields probe) was used to sample, record and store 3 axis static and ac magnetic fields waveforms simultaneously, at multiple locations.

    Understanding of the mechanisms driving our daily face-to-face encounters is still limited; the field lacks large-scale datasets describing both individual behaviors and their collective interactions. However, here, with the help of travel smart card data, we uncover such encounter mechanisms and structures by constructing a time-resolved in-vehicle social encounter network on public buses in a city (about 5 million residents). Using a population scale dataset, we find physical encounters display reproducible temporal patterns, indicating that repeated encounters are regular and identical. On an individual scale, we find that collective regularities dominate distinct encounters’ bounded nature. An individual’s encounter capability is rooted in his/her daily behavioral regularity, explaining the emergence of “familiar strangers” in daily life. Strikingly, we find individuals with repeated encounters are not grouped into small communities, but become strongly connected over time, resulting in a large, but imperceptible, small-world contact network or “structure of co-presence” across the whole metropolitan area. Revealing the encounter pattern and identifying this large-scale contact network are crucial to understanding the dynamics in patterns of social acquaintances, collective human behaviors, and—particularly—disclosing the impact of human behavior on various diffusion/spreading processes.

    Advances in wide area network service offerings, coupled with comparable developments in local area network technology have enabled many research sites to keep their offsite network bandwidth ahead of demand. For most sites, the more difficult and costly aspect of increasing wide area network capacity is the local loop, which connects the facility LAN to the wide area service provider(s). Fermilab, in coordination with neighboring Argonne National Laboratory, has chosen to provide its own local loop access through leasing of dark fiber to nearby network exchange points, and procuring dense wave division multiplexing (DWDM) equipment to provide data channels across those fibers. Installing and managing such optical network infrastructure has broadened the Laboratory's network support responsibilities to include operating network equipment that is located off-site, and is technically much different than classic LAN network equipment. Effectively, the Laboratory has assumed the role of a local service provider. This paper will cover Fermilab's experiences with deploying and supporting a Metropolitan Area Network (MAN) infrastructure to satisfy its offsite networking needs. The benefits and drawbacks of providing and supporting such a service will be discussed.

  19. Increased tornado hazard in large metropolitan areas

    Cusack, Stephen

    2014-11-01

    The tornado climate was compared between large metropolitan areas and neighbouring non-metro cities using modern tornado reports in the Storm Prediction Center (SPC) archives. Twenty large metro areas in the higher-risk region of the U.S. were used to boost sample sizes hence robustness of results. Observational biases were minimised by using the most densely populated zips. The analysis found 50% greater tornado frequency and a thicker-tailed severity distribution in metro areas compared to the non-metro cities. These differences are significant at the 1% level. Regarding tornado frequency, the primary question is whether the raised occurrence rates in metro areas are due to observation biases or real differences in tornado climate. Past studies found no relative biases at the population densities used here, whereas there are two potential urban drivers of tornadogenesis. First, the urban heat island raises the storm severity above and downwind of main urban areas, as recorded in precipitation and lightning datasets. Second, the increased surface roughness over metro areas raises low-level shear which in turn has been found to be favourable for tornadogenesis. Modification of convective storms over large metro areas is the more plausible explanation of raised tornado frequency. The drivers of a thicker-tailed tornado severity distribution in metro areas are less certain. Potential causes include: increased debris-loading in metro tornadoes; modification of storms' lower boundary layer by increased surface roughness in metro areas; the reduced density of damage indicators in non-metro cities.

    The combination between quantitative and qualitative research, "Homelessness among the Elderly in Bangkok Metropolitan" aimed to study causes of homelessness, patterns of living, problems, health status, social and health needs. Purposive sampling of 60 older homeless people could be divided into two groups; temporary and permanent homeless. Causes of homelessness were health problems, money problems, family background, emotional management, cultural sensitivities, limitation of extended family, financial management, political control, and domestic violence. Their living problems included:financial insecurity, police suppression, social and medical services, attacks from the young generations, sexual harassment, stealing, and social hierarchy of homelessness. 63.3% reported having hearing problems and a peptic ulcer before becoming homeless. These evolved into musculo-skeletal problems, accident-injuries, and skin diseases. 95% performed ADL/IADLs independently, 78.3% were depressed, 5% diagnosed with severe stress depression. 70% rated themselves happier than the rest ofthe population, and 75% were identified as having normal cognition. 58.3% had a good relationship with a religious network, 55% still had some contacts with theirfamily members. More than 90% indicated that they were satisfied, could sustainin a life on the street, were happy with theirfreedom, liked being close to green areas, learned about human life,fulfilled the dhamma, and felt close to the king.

  2. Acid aerosols in the Pittsburgh Metropolitan area

    McCurdy, Thomas; Zelenka, Michael P.; Lawrence, Philip M.; Houston, Robert M.; Burton, Robert

    This article presents data on ambient concentrations of selected acidic aerosols at four existing monitoring sites in the Pittsburgh PA metropolitan area. The data were collected by staff of the Allegheny County Health Department, Division of Air Quality during the summer and fall of 1993. The sampling protocol was focused on obtaining 24 h-average ammonia, ammonium, acidic sulfates, and particle strong acids data on a 2 to 3 day cycle. The data were obtained using Harvard University School of Public Health's "Short-HEADS" annular denuder sampling train. The Pittsburgh area is of interest because it is downwind of a major regional source of sulfur and nitrogen emissions from coal-burning power plants: the Ohio River Valley. The data presented here indicate that ground-level concentrations of acidic aerosols in Pittsburgh are highly correlated spatially and that many pollutants are higher on days when ground-level wind direction vectors indicate that wind is coming from the southwest rather than from the Pittsburgh source area itself. The monitoring site that is most upwind of the Pittsburgh source area - South Fayette - has particle strong acid levels about twice those of sites closer in to the Pittsburgh central business district.

    To mitigate climate change, governments at multiple levels are developing policies to decrease anthropogenic carbon dioxide (CO2) emissions. The City of Portland (Oregon) and Multnomah County have adopted a Climate Action Plan with a stated goal of reducing emissions to 80% below 1990 levels by 2050. The transportation sector alone accounts for about 40% of total emissions in the Portland metropolitan area. Here we show a new street-level model of on-road mobile CO2 emissions for the Portland, OR metropolitan region. The model uses hourly traffic counter recordings made by the Portland Bureau of Transportation at 9,352 sites over 21 years (1986-2006), augmented with freeway loop detector data from the Portland Regional Transportation Archive Listing (PORTAL) transportation data archive. We constructed a land use regression model to fill in traffic network gaps with traffic counts as the dependent variable using GIS data such as road class (32 categories) and population density. The Environmental Protection Agency (EPA) MOtor Vehicle Emission Simulator (MOVES) model was used to estimate transportation CO2 emissions. The street-level emissions can be aggregated and gridded and used as input to atmospheric transport models for comparison with atmospheric measurements. This model also provides an independent assessment of top-down inventories that determine emissions from fuel sales, while being an important component of our ongoing effort to assess the effectiveness of emission mitigation strategies at the urban scale.

    To evaluate knowledge of and disposition towards organ and tissue donation for transplantation among the adult population of metropolitan Guadalajara, Jalisco, Mexico. A survey was conducted by personal interview with street-recruited persons over 18 years of age using a 29-item questionnaire. Metropolitan Guadalajara was divided into four municipalities and a proportional number of interviews was assigned to each one based on number of inhabitants, socio-economic stratum, age and gender. Four hundred individuals were interviewed. Approximately 80% knew about organ donation and 65% knew that it was legal; however, only 24% had discussed the topic with their relatives. Seventy-one percent did not know how to donate organs and only 25% knew about organ donor cards. On the other hand, 66% were willing to donate, 16.5% would not donate and 17% were undecided. Bodily mutilation was the main reason (40%) given to not donate. 89% would authorize organ donation from a deceased relative, assuming the relative had previously expressed the desire to donate; on the contrary, only 29% would give such an authorization without their relative's prior consent. Finally, 65% considered the driver's license an adequate mean to express their desire to donate and 50% considered the information the mass media disseminated on the subject to be insufficient. The majority of the metropolitan Guadalajara population knew about organ donation and would be willing to donate their organs. However, a high percentage did not know how to donate and considered the information disseminated on the subject insufficient. An on-going mass media campaign could resolve this matter and hopefully increase organ donation among this population.

  5. Private sector's role in public transportation in New York City: regulation and contracting. Technical report, September 1986-March 1987

    Sparrow, R.; Eichenthal, D.

    1987-06-01

    This report examines the role of the privately owned and operated component of New York City's public-transportation system, including buses, vans, and taxis. Particular attention is given to the nature, rationale, and impact of governmental regulation of private carriers. Additionally, the report explores the potential for increased contracting by the Metropolitan Transportation Authority with private providers. The study found serious inadequacies in New York City's regulation of private transit companies, including harmful fragmentation of regulatory authority and unwarranted delays in the processing of applications. Tied to the regulatory framework is a bus-subsidization system which contains significant disincentives for good management, marketing, and financial practices. These failings have contributed to rider dissatisfaction with transit service as well as the development of extensive illegal and extralegal transit services such as unregulated buses, vans, and cabs.

    The recent seismicity catalogue of metropolitan France Sismicité Instrumentale de l'Hexagone (SI-Hex) covers the period 1962-2009. It is the outcome of a multipartner project conducted between 2010 and 2013. In this catalogue, moment magnitudes (M w) are mainly determined from short-period velocimetric records, the same records as those used by the Laboratoire de Détection Géophysique (LDG) for issuing local magnitudes (M L) since 1962. Two distinct procedures are used, whether M L-LDG is larger or smaller than 4. For M L-LDG >4, M w is computed by fitting the coda-wave amplitude on the raw records. Station corrections and regional properties of coda-wave attenuation are taken into account in the computations. For M L-LDG ≤4, M w is converted from M L-LDG through linear regression rules. In the smallest magnitude range M L-LDG <3.1, special attention is paid to the non-unity slope of the relation between the local magnitudes and M w. All M w determined during the SI-Hex project is calibrated according to reference M w of recent events. As for some small events, no M L-LDG has been determined; local magnitudes issued by other French networks or LDG duration magnitude (M D) are first converted into M L-LDG before applying the conversion rules. This paper shows how the different sources of information and the different magnitude ranges are combined in order to determine an unbiased set of M w for the whole 38,027 events of the catalogue.

  9. Detroit, Michigan metropolitan area photographed from Skylab

    NASA Image and Video Library

    1973-08-05

    SL3-83-0152 (July-September 1973) --- A near vertical view of the metropolitan Detroit, Michigan area is seen in this Skylab 3 Earth Resources Experiments Package S190-B (five-inch Earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The 25-mile long Detroit River drains the smaller body of water (Lake St. Clair) and flows southwestward separating Detroit from Windsor, Ontario, and empties into Lake Erie. The Detroit River handles a great deal of Great Lakes barge and ship traffic. Major streets and thoroughfares radiating from the city are clearly visible. Fighting Island is the highly reflective, white area located almost in the center of the picture. This high reflectivity is caused by the functional use of the island-disposal ponds for chemical salts. Sedimentation and/or pollution patterns in the area provide interesting visual phenomena for speculation and analysis. Distinct and rather unique cultivated field patterns can be observed south and east of Windsor, Ontario. This is a direct result of an English survey and land tenure system which was utilized when the area was settled. New areas of residential development are fairly easy to differentiate from older, established residential areas. Vegetation and extent of area coverage can be determined. The Oakland County Planning Commission and the Federal Bureau of Outdoor Recreation working closely with Irv Sattinger of the Environmental Research Institute of Michigan (University of Michigan) are presently processing and analyzing photographic and Multispectral scanner data to determine its usefulness for recreation and open space site studies for this area.

    2007-12-01

    High-resolution near-surface geologic information is essential for seismic hazard reduction in urban areas. Traditionally, a seismic source within the area of study is always desirable for getting the high-resolution information. However, natural earthquake does not usually conveniently occur during periods of seismic observation. Meanwhile, explosive and/or vibrating sources are prohibited to be used in cities. To overcome these limitations for addressing urban seismic hazard reduction, microtremors, the ambient noise of micro-motions in the ground, are becoming valuable sources for extracting the much needed earthquake engineering parameters in urban settings. Using 30 three-component seismometers we have collected microtremor data at more than 1,000 sites in metropolitan Beijing area in the summer of 2007. The data were collected in two ways: 1) along two major roads running roughly orthogonal in NW and NE directions centered in the city center with 200-m seismometer spacing and minimum measurement duration of 1 hour; and 2) seismometer spacing of approximately 1-km that covered the entire area inside Beijing's 5th Beltway. The data are processed with both the horizontal to vertical spectral ratio method (H/V) and space correlation method. The delineated shear wave velocity and the bedrock interface mapping are compared with results by other means. Meanwhile, the newly obtained information on ground motion fundamental frequency and amplification factor will provide further constraints on seismic hazard analysis to those critical structures of the 2008 Summer Olympic Game. This project is supported by the Ministry of Science and Technology of China.

    2011-08-01

    To a great extent, research on geographic accessibility to mammography facilities has focused on urban-rural differences. Spatial accessibility within urban areas can nonetheless pose a challenge, especially for minorities and low-income urban residents who are more likely to depend on public transportation. To examine spatial and temporal accessibility to mammography facilities in the Atlanta metropolitan area by public and private transportation, we built a multimodal transportation network model including bus and rail routes, bus and rail stops, transfers, walk times, and wait times. Our analysis of travel times from the population-weighted centroids of the 282 census tracts in the 2-county area to the nearest facility found that the median public transportation time was almost 51 minutes. We further examined public transportation travel times by levels of household access to a private vehicle. Residents in tracts with the lowest household access to a private vehicle had the shortest travel times, suggesting that facilities were favorably located for women who have to use public transportation. However, census tracts with majority non-Hispanic black populations had the longest travel times for all levels of vehicle availability. Time to the nearest mammography facility would not pose a barrier to women who had access to a private vehicle. This study adds to the literature demonstrating differences in spatial accessibility to health services by race/ethnicity and socioeconomic characteristics. Ameliorating spatial inaccessibility represents an opportunity for intervention that operates at the population level.

    Low-income women with breast cancer who rely on public transportation may have difficulty in completing recommended radiation therapy due to inadequate access to radiation facilities. Using a geographic information system (GIS) and network analysis we quantified spatial accessibility to radiation treatment facilities in the Atlanta, Georgia metropolitan area. We built a transportation network model that included all bus and rail routes and stops, system transfers and walk and wait times experienced by public transportation system travelers. We also built a private transportation network to model travel times by automobile. We calculated travel times to radiation therapy facilities via public and private transportation from a population-weighted center of each census tract located within the study area. We broadly grouped the tracts by low, medium and high household access to a private vehicle and by race. Facility service areas were created using the network model to map the extent of areal coverage at specified travel times (30, 45 and 60 min) for both public and private modes of transportation. The median public transportation travel time to the nearest radiotherapy facility was 56 min vs. approximately 8 min by private vehicle. We found that majority black census tracts had longer public transportation travel times than white tracts across all categories of vehicle access and that 39% of women in the study area had longer than 1 h of public transportation travel time to the nearest facility. In addition, service area analyses identified locations where the travel time barriers are the greatest. Spatial inaccessibility, especially for women who must use public transportation, is one of the barriers they face in receiving optimal treatment.

  14. Metropolitan Influences on Migration into Poor and Nonpoor Neighborhoods*

    South, Scott J.; Pais, Jeremy; Crowder, Kyle

    2011-01-01

    Data from the Panel Study of Income Dynamics and three decennial U.S. censuses are used to examine the influence of metropolitan-area characteristics on black and white households' propensity to move into poor versus nonpoor neighborhoods. We find that a nontrivial portion of the variance in the odds of moving to a poor rather to a nonpoor neighborhood exists between metropolitan areas. Net of established individual-level predictors of inter-neighborhood migration, black and white households are more likely to move to a poor or extremely poor tract rather than to a nonpoor tract in metropolitan areas containing many poor neighborhoods and a paucity of recently-built housing in nonpoor areas. Blacks are especially likely to move to a poor tract in metropolitan areas characterized by high levels of racial residential segregation and in which poor tracts have a sizeable concentration of blacks. White households are more likely to move to a poor than to a nonpoor tract in metropolitan areas that have comparatively few African Americans. PMID:21625368

  16. Envisioning a metropolitan foodshed: potential environmental consequences of increasing food-crop production around Chicago

    NASA Astrophysics Data System (ADS)

    Bowen, E. E.; Martin, P. A.; Schuble, T. J.

    2009-12-01

    Nationwide, cities are increasingly developing policies aimed at greater sustainability, particularly focusing on reducing environmental impact. Such policies commonly emphasize more efficiently using energy to decrease the greenhouse gas (GHG) footprint of the city. However, most plans ignore the food system as a factor in regional energy use and GHG emissions. Yet, the food system in the United States accounts for ~20% of per capita greenhouse gas emissions. Local, sustainable food production is cited as one strategy for mitigating GHG emissions of large metropolitan areas. “Sustainable” for regional agriculture is often identified as small-scale, diversified food crop production using best practices management. Localized food production (termed “foodshed”) using sustainable agriculture could mitigate climate change in multiple ways: (1) energy and therefore CO2-intensive portions of the conventional food system might be replaced by local, lower-input food production resulting in carbon offsets; (2) increased regional carbon storage might result from well-managed food crop production vs. commodity crop production; and (3) averted N2O emissions might result from closing nutrient cycles on agricultural lands following changes in management practices. The broader implications for environmental impact of widespread conversion to sustainable food crop agriculture, however, remain largely unknown. We examine the Chicago metropolitan region to quantify the impact of increased local food production on regional energy efficiency and GHG emissions. Geospatial analysis is used to quantify the resource potential for establishing a Chicago metropolitan foodshed. A regional foodshed is defined by minimizing cost through transportation mode (road, rail, or water) and maximizing the production potential of different soil types. Simple biogeochemical modeling is used to predict changes in N2O emissions and nutrient flows following changes in land management practices

    1985-06-01

    There is concern over persons who fail to attend family planning clinics without reason. The represents 1 of the major stumbling blocks to a successful family planning program. The author investigated factors associated with clinic dropout among black women in a metropolitan area (Capetown, South Africa). Almost 1/2 of those who ceased to attend had a good reason for doing so. The main findings regarding the other defaulters included a lack of motivation among black women to prevent uplanned pregnancies through temporary contraception and that the program may not have met all of the public needs. In this regard, specific reference is made to the need of those women who no longer bring their youngest child to the child health clinic as family planning services are usually integrated into such a clinic.

    1991-01-01

    The authors report the results of an investigation into the possible association between air pollution and infant mortality from pneumonia in the Rio de Janeiro Metropolitan Area. This investigation employed multiple linear regression analysis (stepwise method) for infant mortality from pneumonia in 1980, including the study population's areas of residence, incomes, and pollution exposure as independent variables. With the income variable included in the regression, a statistically significant association was observed between the average annual level of particulates and infant mortality from pneumonia. While this finding should be accepted with caution, it does suggest a biological association between these variables. The authors' conclusion is that air quality indicators should be included in studies of acute respiratory infections in developing countries.

  5. Uber and Metropolitan Traffic Fatalities in the United States.

    PubMed

    Brazil, Noli; Kirk, David S

    2016-08-01

    Uber and similar rideshare services are rapidly dispersing in cities across the United States and beyond. Given the convenience and low cost, Uber has been characterized as a potential countermeasure for reducing the estimated 121 million episodes of drunk driving and the 10,000 resulting traffic fatalities that occur annually in the United States. We exploited differences in the timing of the deployment of Uber in US metropolitan counties from 2005 to 2014 to test the association between the availability of Uber's rideshare services and total, drunk driving-related, and weekend- and holiday-specific traffic fatalities in the 100 most populated metropolitan areas in the United States using negative binomial and Poisson regression models. We found that the deployment of Uber services in a given metropolitan county had no association with the number of subsequent traffic fatalities, whether measured in aggregate or specific to drunk-driving fatalities or fatalities during weekends and holidays.

Available data and their reliability are first analysed. The six metropolitan provinces reveal a very high concentration of foreign population, Rome and Milan in particular. The general picture is that of an increasing concentration of foreign residents in the capital city, but at the same time of the growing scattering in the metropolitan municipalities. Estimates for illegal or irregular migrants, obtained by applying the shares of illegality [emerging] from sample surveys to the regular stock, suggest that the percentage of illegal and irregular immigrants is particularly high in the provinces of Rome and Naples and is mainly connected with flows from Eastern Europe and North Africa."

    -HCO3 or Na-HCO3 types. TDS (107-14,500 /L), EC (225-25,500 μS/cm), salinity (100-15,500 /kg), Na+ (13.39-2,866 /L) and Cl- (15.3-7,066 /L) concentrations are also higher than those of general groundwater. This fact indicates that groundwater in study area was polluted by saline water and/or anthropogenic sources. TCE, PCE, 1.1.1-trichloroethane (TCA) were analyzed by Busan Metropolitan City Institute of Health &Environment. PCE and TCA are not detected most of sites, while TCE is detected most of the sites and exceeds drinking water standard of Korea 0.03 /L. It is considered that TCE was derived from variety contamination sources such as car-washing centers, transportation companies, iron molding factories and waste treating companies. Risk assessment to human health and environmental resources by groundwater contamination was conducted. The RBCA Tool Kit for Chemical Releases can be used for the risk assessment at Tier 1 and Tier 2. The risk assessment determines risk-based concentration of constituents of concerns (COCs) that moves through groundwater, soil and air. It also evaluates carcinogenic risk and toxic effect when receptor exposures to the COCs. Tier 1 analysis determines risk-based screening levels (RBSLs) for one-site exposure. Tier 2 analysis evaluates RBSL and/or site-specific target levels (SSTLs) for both on-site and off-site receptor. RBSLs were calculated as 2.2E-2 /L for TCE and as 4.7E-3 /L for PCE at Tier 1 risk assessment. Average concentrations of TCE and PCE from measuring the groundwater samples were 0.15 mg/L and 0.016 mg/L, respectively. The actual measured values are higher than the RBSLs. Carcinogenic risk of TCE to animals was identified as B2 (inadequate or no human evidence but sufficient animal evidence). From this result, we will conduct the further detail risk assessment at Tier 2 level before conducting groundwater remediation.

  8. The food environment and adult obesity in US metropolitan areas.

    PubMed

    Michimi, Akihiko; Wimberly, Michael C

    2015-11-26

    This research examines the larger-scale associations between obesity and food environments in metropolitan areas in the United States (US). The US Census County Business Patterns dataset for 2011 was used to construct various indices of food environments for selected metropolitan areas. The numbers of employees engaged in supermarkets, convenience stores, full service restaurants, fast food restaurants, and snack/coffee shops were standardised using the location quotients, and factor analysis was used to produce two uncorrelated factors measuring food environments. Data on obesity were obtained from the 2011 Behavioral Risk Factor Surveillance System. Individual level obesity measures were linked to the metropolitan area level food environment factors. Models were fitted using generalised estimating equations to control for metropolitan area level intra-correlation and individual level sociodemographic characteristics. It was found that adults residing in cities with a large share of supermarket and full-service restaurant workers were less likely to be obese, while adults residing in cities with a large share of convenience store and fast food restaurant workers were more likely to be obese. Supermarkets and full-service restaurant workers are concentrated in the Northeast and West of the US, where obesity prevalence is relatively lower, while convenience stores and fast-food restaurant workers are concentrated in the South and Midwest, where obesity prevalence is relatively higher. The food environment landscapes measured at the metropolitan area level explain the continental-scale patterns of obesity prevalence. The types of food that are readily available and widely served may translate into obesity disparities across metropolitan areas.

  16. Three-dimensional behaviour of photochemical pollutants covering the Tokyo metropolitan area

    NASA Astrophysics Data System (ADS)

    Uno, Itsushi; Wakamatsu, Shinji; Suzuki, Makoto; Ogawa, Yasushi

    The spatial distribution and transport process of photochemical pollutants covering the Tokyo Metropolitan Area in Japan were investigated from 31 July to 2 August 1979. In the experiment, the vertical profiles of pollutants were observed using four instrumented aircraft. This paper mainly considers the transport process of the polluted air mass using three-dimensional trajectory analysis in which the wind field was determined by objective analysis techniques from pilot-balloon observation data. In the Tokyo Metropolitan Area the sea-land breeze circulation is an important factor in photochemical oxidant formation inland when the geostrophic wind is weak. The night-time radiation inversion which persists into the early morning prevents the dispersion of primary pollutants emitted from the big coastal industrial zones around Tokyo Bay. These pollutants are then advected by the land breeze to the Sagami Bay area which acts as storage tank. Conversion of such pollutants results in a high O 3 air mass inland with the penetration of the sea breeze. The sea breeze layer is thermally stable and inhibits vertical mixing of NO x. On the other hand, at the front of the sea breeze zone, a highly turbulent area transports the NO x to 1000-1500 m above mean sea level. Polluted air masses, with O 3 concentration exceeding 100 ppb, were observed at 500-1000 m on both 31 July and 1 August 1979. The maximum O 3 concentration on the 2nd day exceeded that on the 1st day. These high O 3 air masses contained aged pollutant and were entrained into the mixing layer as the depth of the mixing layer increased. This accelerated the formation rate of secondary pollutants. These early morning, high O 3 concentrations, and the storage capacity of the Sagami Bay area, are important factors in the time scale of air pollution phenomena in this region.

  20. Simulation of Land Use Changes in Metropolitan Suburban Area: A Case Study of Sholinganallur

    NASA Astrophysics Data System (ADS)

    Kanchanamala, S.; Sekar, S. P.

    2015-01-01

    Land use planning for a city is a complex activity involving assumptions on likely development. It is also a complex system wherein the planners need to recognize various influencing parameters. Verifying the factors influencing development over a period of time, that too for a vast area of metropolitan city is a herculean task. In order to keep them in control, planners need tools and techniques which may be handy to operate, allowing the planners at the beginning itself to have alternative plans as well as interim evaluation of the achievement of a plan. Absence of such a tool in the hands of the planners forces a plan to be monolithic and left with no interim evaluation. This research has identified four variables which highly influence land use change namely accessibility to transportation network; physical quality and land availability; proximity to work places; and plans and policies. A simulation model is developed to validate these variables for the suburbs of Chennai Metropolitan Area. Land use scenario for residential land use are simulated for the sub urban area-Sholinganallur for the years 1980, 1991, 2006 and 2011. Over 65 % agreement is observed in residential land use between the actual land use and the simulated extents.

  1. Increasing spatiotemporal resolution of several major pollutant species in the Atlanta Metropolitan Area

    NASA Astrophysics Data System (ADS)

    Brosius, A. L.; Luong, K. Y.

    2014-12-01

    The American Lung Association cited Atlanta, Georgia, as one of the top 20 most polluted U.S. cities in 2014. Heavy air and ground transportation traffic contribute to the production of carbon dioxide (CO2), particulate matter (PM), and tropospheric ozone (O3) for the Atlanta Metropolitan Area (AMA). Hartsfield-Jackson Atlanta International Airport contributes significantly to the emission of these pollutants and their precursors. This study focuses on enhancing spatiotemporal resolution of CO2, PM, and O3in near-surface (ground to 50m) air columns by using Arduino-based sensors. The city of Decatur, due to its proximity to the airport, is the study site for the investigation of target pollutant concentrations. The results of this study, combined with other metropolitan air quality data sets, can be used to verify projected trends and append seasonal data. An understanding of the pollutant concentration distributions throughout the near-surface air column is vital to providing insight into the fluctuation of urban area pollutants.

  4. Extended commuting and migration in the Taipei metropolitan area.

    PubMed

    Chen, C

    1992-12-01

    The aim of this study was to examine the relationship between the relative size and extent of labor force commuting and migration among the population 15 years and older in the Taipei, Taiwan, metropolitan area (city, periphery, and other areas), and the variation by labor group. The hypothesis was that extended commuting patterns occur before migration and migrants and commuters come from different groups. There was a well-developed transportation system for long commuters. It was also suspected that commuting and migration were alternatives for each other, because of the long commutes (over 40 minutes) and the young, unmarried age groups associated with migration. Data were obtained from a stratified sample from the October round of the labor force survey in 1988. Data were stratified by degree of urbanization and industrial composition, and within village level units. The migration streams were identified as from Taipei periphery to the city, from other areas to the city, from the city to the periphery, from other areas to the periphery, from the city to other areas, and from the periphery to other areas. Commuter patterns were designated by commuting from the city to the periphery, from the city to other areas, from the periphery to the city, from the periphery to other areas, from other areas to the city, and from other areas to the periphery. The sample population of 8,384,587 was greater than the official estimates by 3.4%. In the weighted sample, 13.5% were missing data, which resulted in an employed population of 1,271,309 persons. The trend has been for stability of population growth of 2% in the city, and a decline to a rate of growth of 1.3% in peripheral areas. Both the city and periphery gained population from other areas: 70,000 and 35,000 persons, respectively; there was a balanced stream between the city and periphery of 30,000 persons. 24.1% of periphery workers were commuters to the city with a commuting population of 250,000 daily.

    Metropolitan Mexico City (MMC) is one of the most polluted urban areas in the world. The authors characterized the morphologic nasal mucosal changes in short-term (less than 30 days) and long-term (more than 60 days) exposures to the polluted southwest MMC atmosphere with high levels of ozone and other contaminants versus a control group of subjects living in a nonpolluted, low-ozone Mexican port. Seventy-six inferior turbinate biopsies were examined. The control group showed normal mucociliary epithelium, whereas the short-exposure group displayed loss of normal epithelium, basal cell hyperplasia, and mild dysplasia (17.64%). In the long-term exposure group, 78.72% of dysplasias were found (59.45% mild and 40.54% moderate) together with severe loss of normal respiratory epithelium, prominent basal cell hyperplasia, squamous metaplasia, and submucosal vascular proliferation. Our findings suggest that southwest metropolitan Mexico City inhabitants develop histopathologic changes in their nasal mucosa on exposure to the polluted city atmosphere.

    Occurrence of fractures is highly dependent on lifestyle. Domestic data should be used when needed. In this cross-sectional study, the authors aim to find the most recent distribution of pediatric fracture types and the attributes of fracture occurrence within a large sample size in a metropolitan area of Turkey.This study consists of 4879 pediatric age patients with a fracture who took advantage of the emergency service of a trauma center in a metropolitan area between March 2010 and December 2013 (1397 days). Date, hour, age, sex, fracture type, and social security status of the patients were studied.A total of 65% of the patients were men and 35% were women. A total of 81% of the fractures were in the upper extremities, whereas 19% of them were in the lower extremities. In 22 patients (0.5%), there were open fractures. Fractures showed some seasonal, daily, and circadian variations. Different types of fractures showed some specific patterns in different age groups. Ankle, elbow, and shoulder fractures were more common in girls, whereas wrist and forearm fractures were more in boys and the difference was statistically significant (P < 0.05).Fractures in pediatric ages vary depending on the age, sex, season, and the hour of the day. Types of fractures show some obvious patterns especially depending on the age. This data can be useful in making optimizations in fracture care units. Considering these specific patterns would enable more effective planning of providing preventive measures for pediatric injuries.

  12. Occurrence and potential sources of pyrethroid insecticides in stream sediments from seven U.S. metropolitan areas

    Kuivila, Kathryn; Hladik, Michelle; Ingersoll, Christopher G.; Kemble, Nile E.; Moran, Patrick W.; Calhoun, Daniel L.; Nowell, Lisa H.; Gilliom, Robert J.

    2012-01-01

    A nationally consistent approach was used to assess the occurrence and potential sources of pyrethroid insecticides in stream bed sediments from seven metropolitan areas across the United States. One or more pyrethroids were detected in almost half of the samples, with bifenthrin detected the most frequently (41%) and in each metropolitan area. Cyhalothrin, cypermethrin, permethrin, and resmethrin were detected much less frequently. Pyrethroid concentrations and Hyalella azteca mortality in 28-d tests were lower than in most urban stream studies. Log-transformed total pyrethroid toxic units (TUs) were significantly correlated with survival and bifenthrin was likely responsible for the majority of the observed toxicity. Sampling sites spanned a wide range of urbanization and log-transformed total pyrethroid concentrations were significantly correlated with urban land use. Dallas/Fort Worth had the highest pyrethroid detection frequency (89%), the greatest number of pyrethroids (4), and some of the highest concentrations. Salt Lake City had a similar percentage of detections but only bifenthrin was detected and at lower concentrations. The variation in pyrethroid concentrations among metropolitan areas suggests regional differences in pyrethroid use and transport processes. This study shows that pyrethroids commonly occur in urban stream sediments and may be contributing to sediment toxicity across the country.

  14. Implications of urban structure on carbon consumption in metropolitan areas

    NASA Astrophysics Data System (ADS)

    Heinonen, Jukka; Junnila, Seppo

    2011-01-01

    Urban structure influences directly or indirectly the majority of all green house gas (GHG) emissions in cities. The prevailing belief is that dense metropolitan areas produce less carbon emissions on a per capita basis than less dense surrounding rural areas. Consequently, density targets have a major role in low-carbon urban developments. However, based on the results of this study, the connection seems unclear or even nonexistent when comprehensive evaluation is made. In this letter, we propose a hybrid life cycle assessment (LCA) method for calculating the consumption-based carbon footprints in metropolitan areas, i.e. carbon consumption, with the emphasis on urban structures. The method is input-output-based hybrid LCA, which operates with the existing data from the region. The study is conducted by performing an analysis of the carbon consumption in two metropolitan areas in Finland, including 11 cities. Both areas consist of a dense city core and a less dense surrounding suburban area.
