摘　　要：考虑现实条件下交通网络的不确定性状态,提出了从确定型网络到不确定型网络状态下出行者路径选择行为的改变,及基于行程时间可靠性的路径选择模型.并将可靠行程时间的路径选择行为纳入到随机交通网络平衡分配模型中,证明了模型的等价性和唯一性.在一个小型测试网络上对模型分配结果进行了测试,测试结果与经验相吻合,表明模型具有较好的现实可行性.Considering the un-deterrninistic property of transportation network, the changes of route choice behavior from deterministic to stochastic transportation network were studied. The route choice behavior based on travel-time reliability was taken into account and brought into the transportation equilibrium model. The equivalence and uniqueness of the solution of model were demonstrated. Numerical results of a small network show that the proposed model can reflect the real traveler＇s route choice behavior in stochastic transportation network.
