Abstract

In this paper, we derive implementable measures of travelers’ willingness to pay to save travel time (vot) and to improve the reliability ( vor) of a given trip. We set out a simple microeconomic model of transport mode choice in which each trip is fully characterized by its price and the statistical distribution of its random travel time, assuming that travelers have expected utility preferences over the latter. We then explore how the votand vor are affected by the statistical distribution of travel time and by travelers’ preferences towards travel time variability.
