Comparison of probabilistic modal-choice models: estimation methods and system inputs. Paper presented at the 51st Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1972.

This research has 3 objectives a) to investigate the relative merits of the 3 methods most widely used in probabilistic modal-choice modeling or in value of time studies, logit, probit and discriminal analyses) to investigate the need for trip segmentation and c) to obtain further evidence on the value of time.
