The multinomial probit model of travel demand is considerably more general but much less tractable than the better-known multinomial logit model. In an effort to determine the effects of using the relatively simple logit model in situations where the assumptions of probit modeling are satisfied...

Multinomial logit models of travel demand are subject to a variety of specification errors that can severely affect the accuracy the models' forecasts. This paper describes some of the important sources of specification errors in logit models, presents numerical illustrations of the errors'...

In this paper, a structural model of the demand for multi-destination non-work travel is developed, and an empirical illustration of the structural model is presented. The structural model is based on the principle of utility maximization and differs from previous utility maximizing models of...
