摘　　要：为了解决拥挤收费政策在不同理性程度群体构成的交通流中的实施效果问题,在逐日路径演化模型的基础上引入拥挤收费政策,建立新的模型以研究拥挤收费条件下出行者逐日路径选择行为.并以一个由2条路径构成的路网为例,探讨了有限理性视野下拥挤收费政策对网络交通流逐日动态演化过程的影响.通过数值实验,分析了拥挤收费条件下网络交通流的演化特征,发现拥挤收费对网络交通流演化的最终状态以及系统平均走行时间有一定的影响;出行者的时间价值、理性程度会影响拥挤收费政策的实施效果.In order to study the impact of congestion pricing policy on traffic flow which is composed of travelers with different rational degree,congestion pricing policy of day-to-day route choice evolution model was introduced and a model to study the behavior of the day-to-day route choice of travelers under the condition of congestion pricing was established. The effects of congestion pricing policy of day-to-day dynamic evolution were discussed by a network consisting of two paths. A numerical experiment was made to analyzed evolution characteristics of the network traffic flow under congestion pricing. It shows that the congestion pricing policy has a certain effect on the evolution result and average travel time. In addition,the value of time and the degree of rationality affect the effect of the implementation of congestion pricing policy.
