WORKSHOP ON MATHEMATICAL STRUCTURES AND UNCERTAINTY. MATHEMATICAL MODELS OF TRAVEL DEMAND: A STATE-OF-THE-ART REVIEW

The modeling of transportation systems has evolved rapidly since the early highway studies of the 1950s. The author has divided the travel demand modeling field into 5 areas: Behavioral theory; measurement; model structure; estimation; and forecasting. In contrast to the rapid progress made in estimation and model structure, there has been little change in behavioral theory because it is extraordinarily complex and difficult to model. The progress in measurement has been somewhat mixed. In the area of forecasting, it is safe to argue that the problem of aggregating demand models across individuals is probably a major concern. There remain serious questions regarding travel demand modeling which has lost much of the momentum that characterized it in the 1970s. The research community sees progress being made only in fringe areas of model structure and estimation with no great applicability; the users of new methods find recent results increasingly unintelligible.
