Land Development Patterns

Case Studies

Albany, New York

A simple incremental land use model is developed and applied to allocate new development based on transportation accessibility. The model is used to test the impacts on congestion, delay, and emissions of induced land development, property tax policies, and policies to shift the location of development within the region.

Envision Utah

A variety of impacts associated with alternative regional development scenarios are measured. Existing and future land use data are manipulated within a GIS raster (grid cell) environment to allocate future development to geographic locations under each scenario.

Sacramento, California

An integrated transportation-land use model is used to test the impacts of a range of transportation and land use policies, including light rail transit, transit-oriented development, HOV and HOT lanes, roadway-oriented development, and pricing. Results are compared to the results of similar scenarios tested with the regional travel demand model.

SPARTACUS (Europe)

An integrated transportation-land use model is used to forecast a range of economic, environmental, and social impacts of alternative transportation strategies in three European cities.
