Previous urban sprawl studies have typically taken a cross-sectional approach without examining how sprawling urban areas are performing over time. Longitudinal studies of individual or household travel behavior and built-environment preference have made some progress in this direction, but very few studies have explored the longitudinal interaction of urban form with transportation and environ...

In the last century territory and layout of cities have undergone important changes with an enlargement in space human settlements. It deserves attention terms principles sustainability, limitation soil consumption, environmental impacts social needs. Then, a holistic vision for definition city its mobility is needed. This paper introduces systemic conceptual framework urban planning by combini...

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...

The future health of ecosystems is arguably as dependent on urban sprawl as it is on human-caused climatic warming. Urban sprawl strongly impacts the urban ecosystems it creates and the natural and agro-ecosystems that it displaces and fragments. Here, we project urban sprawl changes for the next 50 years for the fast-growing Southeast U.S. Previous studies have focused on modeling population d...

The Land Transformation Model (LTM), which has been developed to forecast urban-use changes in a grid-based geographical information system, was used to explore the consequences of future urban changes to the years 2020 and 2040 using non-urban sprawl and urban-sprawl trends. The model was executed over a large area containing nine of the major coastal watersheds of eastern Lake Michigan. We fo...

Monitoring urban growth and measuring urban sprawl is essential for improving urban planning and development. In this paper, we introduce a supervised approach for the delineation of urban areas using commonly available topographic data and commercial GIS software. The method uses a supervised parameter optimization approach along with buffer-based quality measuring method. The approach was dev...

Land use changes result from population growth and migration of poor rural people to urban areas for economic opportunities. Changes in land use directly influence the regional air quality, energy consumption and climate at global, regional and local scales. Controlled, coordinated and planned urbanization is a gift to the human society. However, unplanned urbanization can be a disaster. Urban ...
