摘　　要：Research about the auto commuter＇s pre-trip route choice behavior ignores the combined influence of the real-time information and all respondents＇ historical information in the existing documents.To overcome this shortcoming,an approach to describing the pre-trip route choice behavior with the incorporation of the real-time and historical information is proposed.Two types of real-time information are investigated,which are quantitative information and prescriptive information.By using the bounded rationality theory,the influence of historical information on the real-time information reference process is examined first.Estimation results show that the historical information has a significant influence on the quantitative information reference process,but not on the prescriptive information reference process.Then the route choice behavior is modeled.A comparison is also made among three route choice models,one of which does not incorporate the real-time information reference process,while the others do.Estimation results show that the route choice behavior is better described with the consideration of the reference process of both quantitative and prescriptive information.已有的出行前信息提供条件下的通勤驾驶员路径选择行为通常忽略实时信息和所有出行者历史出行信息之间的相互影响,针对这一缺点,提出实时信息和历史信息共同作用下的出行前路径选择行为.通过利用有限理性理论,首先研究了历史信息对定量型和描述型2种实时信息的影响,结果发现历史信息对定量型实时信息的参考过程有重要影响,但对描述型信息的影响很小.在此基础上,基于考虑和不考虑实时信息的参考过程建立了3种路径选择模型,预测结果显示,在定量型和描述型信息2种情况下,考虑实时信息参考过程的路径选择模型能更好地描述驾驶员路径选择行为.
