First, basedon travelers' route choice behavior, the reliable travel timeconfidence level (RTTCL), which is the probability that a triparrives within the shortest average travel time plus theacceptable travel time difference, is defined. Then, areliability-based user equilibrium (RUE) model, whichhypothesizes that for each OD pair no traveler can improvehis/her RTTCL by unilaterally changing routes, is built.Since the traditional traffic assignment algorithms are notfeasible to solve the RUE model, a quasi method of successiveaverage (QMSA) is developed. Using Nguyen-Dupuis andSioux Falls networks, the model and the algorithm are tested.The results show that the QMSA algorithm can rapidlyconverge to a high accuracy for solving the proposed RUEmodel, and the RUE model can provide a good response totravelers' behavior in the stochastic network. 关 键 词：user EQUILIBRIUM RELIABLE TRAVEL TIME acceptabletravel TIME difference CONFIDENCE level quasi method ofsuccessive AVERAGE
