OBJECTIVES We sought to determine the association between urban sprawl and traffic fatalities. METHODS We created a sprawl index by applying principal components analysis to data for 448 US counties in the largest 101 metropolitan areas. Regression analysis was used to determine associations between the index and traffic fatalities. RESULTS For every 1% increase in the index (i.e., more com...

This paper examines the relationship between job sprawl and the spatial mismatch between blacks and jobs. Using data from a variety of sources including the U.S. Census and the ZIP Code Business Patterns of the U.S. Department of Commerce, I control extensively for metropolitan area characteristics and other factors. In addition, I use metropolitan area physical geography characteristics as ins...

Rising dependence on the automobile, rapid population growth, and migration out of existing urban centers in search of affordable housing are some of the factors that have reshaped the American landscape into a pattern of low-density, sprawl...

Monitoring and simulating urban sprawl and its effects on land-use patterns andhydrological processes in urbanized watersheds are essential in land-use and waterresourceplanning and management. This study applies a novel framework to the urbangrowth model Slope, Land use, Excluded land, Urban extent, Transportation, andHillshading (SLEUTH) and land-use change with the Conversion of Land use and...

The issues of urban sprawl are current in both global research as well the sphere activities by public authorities developed and developing countries. Urban is a phenomenon that goes beyond administrative boundaries cities, which forces monitoring on wide territorial scale, i.e., regional national.

A decade ago, compactness/sprawl indices were developed for metropolitan areas and counties which have been widely used in health and other research. In this study, we first update the original county index to 2010, then develop a refined index that accounts for more relevant factors, and finally seek to test the relationship between sprawl and traffic crash rates using structural equation mode...

about half a century ago, following the introduction of urban sprawl up concept, various studies have been conducted to describe the mechanism and the formation of this phenomenon. some of these studies aimed at finding the negative and positive impacts of such phenomenon on urban area with emphasis on how such concept may be looked open from environmental, economical and social perspectives.th...

This article is concerned with the economics of excessively large and socially costly suburban expansion and attempts to summarize and organize the main economic arguments associated with sprawl due to single-family residential home construction.
