| 摘 要： | 考虑出行者有限理性的特点,以累积前景理论为基础, 建立了考虑路段通行能力退化情况下的用户均衡模型, 并说明了解的存在性. 在数值算例中, 分别采用期望效用理论和累积前景理论进行计算, 对比了两者在描述出行 者路径选择行为上的差异. 结果表明, 累积前景理论能够克服期望效用理论的不足, 更好地描述出行者路径选择的决策过程.

| Abstract: | This paper establishes a user equilibrium model based on the cumulative prospect theory (CPT) for a degradable transport network and shows the solution existence of the model. In numerical experiments, the study calculates the network equilibrium flow pattern based on the expected utility theory (EUT) and CPT, respectively. The results of the comparison between them indicate that the CPT-based model is superior to the EUT-based model in describing the travelers' route choice decision processes. |
