Travelers always exhibit bounded rationality due to limited perception. Based on the theory of bounded rationality, switching thresholds under different patterns of information are analyzed in this paper. An experiment platform including four scenarios, such as historical descriptive information, real-time descriptive information, historical travel time information and real-time travel time information is designed to obtain the participants’ travel preference and route choice behavior. The relationship among route switching behavior, perceived travel time difference and travelers’ preference is analyzed based on experiment’s results. The Probit regression method is utilized for calibrating the switching threshold under different patterns of information. The results prove the dissimilarity of switching thresholds in diverse patterns of information. The switching threshold under real-time information is lower than that under historical information. The estimated results of risk parameters prove that the traveler has a slight tendency to pursue risk. The method proposed in this paper can effectively quantify the degree of bounded rationality.

由于知觉有限，旅行者总是表现出有限的理性。基于有限理性理论，分析了不同信息模式下的切换阈值。设计了一个包含历史描述信息，实时描述信息，历史旅行时间信息和实时旅行时间信息四个场景的实验平台，以获取参与者的旅行偏好和路线选择行为。根据实验结果，分析了路径切换行为，感知的旅行时差和旅行者的偏好之间的关系。Probit回归方法用于在不同信息模式下校准切换阈值。结果证明了在各种信息模式下切换阈值的不相似性。实时信息下的切换阈值低于历史信息下的切换阈值。风险参数的估计结果证明，旅行者倾向于追求风险。本文提出的方法可以有效地量化有限理性程度。
