Subjective time savings in interurban travel : an empirical study. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

Travel time savings are usually estimated on the basis of objectively measured times. Such objective measures are assumed to correspond to the mean of a distribution of subjective time savings as reported by travelers. In a multimodal, single-route, interurban passenger survey, this was not found to be the case.
