研究驾驶员的路线选择行为有助于提高既有道路网络(特别是城市交通网络)的利用率,从而改善交通状况.本文从宏观角度分析存在实时交通信息条件下驾驶员路线选择行为的时间演化特征,认为路线选择行为具有随机不确定性,在设计交通诱导系统或交通信息系统时,必须考虑扰动因素影响,才能保证系统有效实现均衡的交通流动态分配。 Studying the driver’s route selection behavior can improve the utilization of the existing road network (especially the urban traffic network) to improve the traffic condition.This paper analyzes the time evolution of the driver’s route selection behavior under the condition of real-time traffic information from a macro perspective Characteristics, it is considered that the route selection behavior has random uncertainty. When designing the traffic guidance system or traffic information system, the influence of disturbance factors must be considered in order to ensure that the system can effectively achieve balanced traffic flow dynamic allocation.
