中文摘要：

根据驾驶者的行为模式建立了一个路径选择模型及排队模型.在高峰时期发生交通事故的情形下,通过对比行驶车辆在配备车载信息系统和未配备交通信息系统两种情况,分析事故瓶颈引起车辆阻塞占用道路长度与事故处理时间的关系的影响,论证交通信息系统对交通瓶颈的改善作用.通过案例分析予以验证.

英文摘要：

According to a traveler＇s behavior model, a route diversion model and a queuing model are proposed. Second, a travelerls behavior is contrasted between equipped and unequipped traveler infor- mation systems under incident conditions during the peak period. The evolution of queue length is considered on a network with two links network considering an incident bottleneck. Traveler information systems impacts are demonstrated which can make the network operate closer to system optimal equilibrium during the incident period. Last, the model is analyzed and validated by a numerical example.
