| 摘 要： | 针对路径选择模型的特点,基于前景理论分析了实际路网中出行者在不同得失状况下的选择行动,进而重点分析了模型中参照点的设定方法.从传统参照点设置方法入手,针对其自由流时间不适用于拥挤路网的弊端,通过结合出行时间预算和有效路径的相关理论,提出了一种更加符合实际的路径选择模型参照点设定方法.算例演算表明,提出的参照点设定方法能有效地反映路网出行者的实际出行行为,特别是在出行者对出行时间要求越严格的情况下,改进方法的优势越明显.

| Abstract: | In this paper,it focused on the characteristics of route choice model.Based on the prospect theory,the travelers' different choices have been analyzed in different gains and losses circumstances of actual road network,and the reference point setting method has been predominantly focused on.Starting from the traditional reference point setting method,in order to resolve the drawbacks that free flow travel time does not apply to network congestion,a more realistic model for reference point setting in route ch... |
