The relationship between urban form, as shaped through transit-oriented urban design, and transportation demand, as represented by regional travel demand forecasting model techniques, is investigated. The research from two studies is synthesized and, through development of travel demand forecasting model enhancements in the form of a subarea model and off-line estimation techniques, a link is sought between data analysis at the regional scale and urban design and land use strategies applied at the local and subregional scales. A methodology for aggregating individual transit-oriented development sites into a subregional growth scenario is described. Findings are reported from use of the subarea model to compare impacts of a transit-oriented growth scenario with a conventional growth scenario for a subregion of suburban communities.
