This article is aimad at exploring urban sprawl as a new leading behavior pattern of cities. Undoubtedly, the traditional city is changing to a landscape dominated by new urban development of low density, road networks and shopping centers. Geographic information technologies have to face the cartographic and quantitative analysis of this new urban spatial structure This article presents a meth...

This paper proposes four metrics to measure sprawl in metropolitan regions as marginal changes in land use over time. The metrics (change in urban housing unit density, marginal land consumption per new urban household, housing unit density in newly urbanized areas and percent of new housing units located in previously developed areas) are computed for all 329 metropolitan areas in the continen...

PURPOSE To determine the relationship between urban sprawl, health, and health-related behaviors. DESIGN Cross-sectional analysis using hierarchical modeling to relate characteristics of individuals and places to levels of physical activity, obesity, body mass index (BMI), hypertension, diabetes, and coronary heart disease. SETTING U.S. counties (448) and metropolitan areas (83). SUBJECTS...

Introduction. – The land take is now a central and diriment issue in many disciplines due to the complex problems involved in the depletion of soil resource from an environmental, economic, urban and social perspective, but it is certainly linked to the phenomenon of urban sprawl. In the short-medium term, the land take is a process as destructive as irreversible. Therefore, a research of the m...

When regular steam ferry service between Brooklyn and Manhattan began in 1814, the first commuter suburb became possible. 1 Suburbs continued to develop slowly but steadily during the 19th and early 20th centuries, thanks to transportation advances such as commuter trains and streetcars, the innovations of early real estate developers, and the urge to live in pastoral tranquility rather than in...

Suburban sprawl is one of the most avidly followed urban issues in the United States today. However, despite the level of attention that is afforded sprawl, their remains relatively little understanding of its determinants and its constitution. Previous attempts to measure sprawl have focused largely on costing out its impacts rather than quantifying its characteristics. Also, the characterizat...

strong sentiment against the phenomenon known as “urban sprawl” has emerged in the United States over the past few years. Critics of sprawl argue that urban expansion encroaches excessively on agricultural land, leading to a loss of amenity benefits from open space as well as the depletion of scarce farmland resources. The critics also argue that the long commutes generated by urban expansion c...

the rapid and sprawl development city in recent decades has created many problems for cities and causing instability in urban environments. the late twentieth century these problems caused a revision in urban planning models and introduction of new models such as the infill development. studies show that third world countries like iran are faced with sprawl development model and should take the...
