Abstract:In July 1992, the Federal Highway Administration (FHWA) issued a solicitation for proposals to redesign the travel demand forecasting process. The purpose of the solicitation was to enable travel behavior researchers to explain how transportation planning models should and could be improved to meet the new forecasting requirements brought on by recent legislation, to address the impacts of new transportation technology, and to exploit the travel behavior theory and methodology that has developed over the past two decades. Four research proposals by Resource Decision Consultants, Inc. (RDC), Caliper Corporation (Caliper), Massachusetts Institute of Technology (MIT)and the Louisiana Transportation Research Center (LTRC) are examined. This paper presents a summary and synthesis of the ideas presented in the four research reports. Its purpose is not to evaluate the merits or deficiencies of individual approaches, nor to recommend an overall "winner" among the four proposals. Rather, it is to identify common themes suggested by several of the research reports, to point out what appear to be critical elements missing from some approaches, and to combine the best aspects of the four approaches into a research plan for improving the current generation of travel demand models. 2 Figures, 1 table, 34 p.
