摘　　要：考虑出行者在模糊信息条件下的动态路径选择行为,提出一种基于路径模糊条件下的选择模型。出行者在一种非饱和状态下的路网结构中,根据各路段行程所需的模糊时间进行路径选择,从而影响其他出行者选择短路径,使整个路网中各路段用户均衡。该模型框架为智能化交通系统的建立提供一定的理论依据,算例结果验证了该模型的有效性和可行性。This paper presents a choice model under fuzzy condition of route considering the travelers beavior of route chioce under information. The travellers choose a path according to fuzzy time of the itinerary sections in a unsaturated road network to make the traffic flow on the whole road-network achieve a user equipment state. The model also applies to the distribution in the balanced of traffic flow in large-scale road network provides some theoretical basis for ITS,and the simulation results verify the validity and feasibility of the model.
