Although sprawl is a growing national debate, there have been few efforts to measure or monitor changes in degree of sprawl over time. By using a methodology that employs census data, this sprawl index allows computation of levels of sprawl and examination of temporal and geographic changes. The results show that sprawl has increased over the past decade in many metropolitan areas. There are im...

There is a considerable literature on the relationship between sprawl and accidents. However, these studies do not account for the spatially correlated effects of sprawl on accidents. In our analysis of 122 jurisdictions in Southeast Michigan, we use a Bayesian spatial autoregressive model to estimate how injuries and fatalities in one jurisdiction are associated with sprawl in that jurisdictio...

Urban sprawl refers to the outgrowth of urban areas caused by uncontrolled, uncoordinated and unplanned growth. This outgrowth seen along the periphery of cities, along highways, and along roads connecting a city, lacks basic amenities like sanitation, treated water supply, primary health centre, etc. as planners were unable to visualise such growth during planning, policy and decision-making. ...

Abstract. According to research to date, sprawl negatively affects the lives of millions of Americans annually. Fortunately, in the U.S., several states have designed and enacted growth management programs to curb its expansion. But have they been effective? Following up on work by just a handful of other research teams, we control for land area, population, fuel cost, per capita income, passen...

Suburban sprawl, a relatively recent phenomenon, is among the most important urban policy issues facing contemporary cities. To date, a well-accepted rationale has not been settled on for explaining and managing the causes of sprawl. Our contention is that consideration of geography is essential—that geographical explanations offer much potential in informing the debate about sprawl. Similarly,...

Urban sprawl refers to the extent of urbanisation, which is a global phenomenon mainly driven by population growth and large scale migration. In developing countries like India, where the population is over one billion, one-sixth of the world’s population, urban sprawl is taking its toll on the natural resources at an alarming pace. Urban planners require information related to the rate of grow...

Debate regarding suburban sprawl in urban studies is contentious. It is fair to say that the phenomenon is not fully understood to satisfaction in the academic, policy, or planning communities and there are a host of reasons why this may be the case. Characterization of sprawl in the literature is often narrative and subjective. Measurement is piecemeal and largely data-driven. Existing studies...

The urban street network is one of the most permanent features of cities. Once laid down, the pattern of streets determines urban form and the level of sprawl for decades to come. We present a high-resolution time series of urban sprawl, as measured through street network connectivity, in the United States from 1920 to 2012. Sprawl started well before private car ownership was dominant and grew...

Urban sprawl has become a significant part of the regional socio-economic progress since the 20th century. The growing demand for urban land brings the issue that urban sprawl caused increasingly prominent. Studies in aboard on urban sprawl are comparatively earlier, mainly including the concept deconstruction in multi-angle, the shape and path of urban sprawl, and the measure of urban sprawl a...

BACKGROUND A number of studies have demonstrated relationships between the perceived built environment and physical activity among adults. However, little is known about whether these associations differ by U.S. region and level of urban sprawl. PURPOSE To examine associations between the perceived built environment and physical activity in U.S. women by region and urban sprawl. METHODS Nur...
