Abstract
The purpose of this paper is to introduce variables ·which may yield explanations of travel behavior which go beyond the economic and transportation-related explanations of existing models. This analysis explores whether improvements can be made in the understanding of individual travel behavior and in the predictive power of travel demand models. This applied emphasis extends the author’s previous work which demonstrated how attitudinal and behavioral information can be used to structure the development and marketing of transportation improvements (Fielding, 1972; Fielding, et.al., 1976).
