COMPREHENSIVE REGIONAL MODELING FOR LONG-RANGE PLANNING: LINKING INTEGRATED URBAN MODELS AND GEOGRAPHIC INFORMATION SYSTEMS. IN: THE AUTOMOBILE

Demonstrated in this study is the sequential linking of two different models that permit the comprehensive evaluation of regional transportation and land use policies. An integrated urban model TRANUS represents both land and travel markets that have both zones and networks. The paper outlines both travel and land use projections from TRANUS to demonstrate the general reasonableness of the results for this first application of a market-based urban model in the U.S. In the second model, the land use projections for each of the 58 zones in the urban model were fed into a Geographic Information System (GIS)-based land allocation model that spatially allocates the several land uses within each zone according to simple accessibility rules. This is the first time to link these two models for regional policy assessments. The results demonstrate the feasibility of linking an integrated urban model and a GIS to produce a spatially detailed set of land use maps.
