Abstract:

In order to ensure on-time arrival when travelers make their trips, the stochastic network assignment model under uncertainty of travel time is investigated. First, based on travelers’ route choice behavior, the reliable travel time confidence level(RTTCL), which is the probability that a trip arrives within the shortest average travel time plus the acceptable travel time difference, is defined. Then, a reliability-based user equilibrium(RUE)model, which hypothesizes that for each OD pair no traveler can improve his/her RTTCL by unilaterally changing routes, is built. Since the traditional traffic assignment algorithms are not feasible to solve the RUE model, a quasi method of successive average(QMSA)is developed. Using Nguyen-Dupuis and Sioux Falls networks, the model and the algorithm are tested. The results show that the QMSA algorithm can rapidly converge to a high accuracy for solving the proposed RUE model, and the RUE model can provide a good response to travelers’ behavior in the stochastic network.
