CHARACTERISTICS OF TRAVEL TIME AND DYNAMIC USER EQUILIBRIUM FOR TRAVEL-TO-WORK

Departure time decisions for travel-to-work are likely to vary in response to work start times and to variations in the travel cost over the course of the peak period of travel. One component of this cost is travel time. This paper summarizes some data on travel times at different departure times for five corridors in Pittsburgh, Pa. Several corridors exhibit substantial variations in average travel time at different departure times. However, the variance of travel time at any departure time is small and displays no systematic relationship to departure time. The paper also considers the various elements of travel cost which may be important for the departure time decision problem, including congestion avoidance, reliability and schedule incompatibility. With the assumption that individuals minimize their own travel cost, several models of dynamic user equilibrium are developed, each corresponding to different user cost functions. These models incorporate the effects of travel time variability. For the covering abstract of the symposium see TRIS (Author/TRRL)
