| 摘 要： | 为研究累积前景理论下随机路网能力退化下限对交通网络均衡的影响，本文构建了考虑随机路网能力退化的连续双参考点用户均衡模型，并证明了解的存在性，设计了求解算法.模型将随机交通网络均衡中的客观不确定性归因为随机路网能力退化下限和设计能力上限，将主观不确定性归因为用户风险态度，并由此内生出行路径期望、方差、最佳到达时间参考点、最早到达时间参考点、累积到达时间价值和网络均衡流量等重要参数.最后通过算例分析了路网能力退化下限对用户和整个交通网络均衡的影响.

| Abstract: | Considering a degradable transportation network and double reference points, a user equilibrium model is developed in this paper. Then we examine the existence of the equilibrium solution, and design a solving algorithm. This model is suitable to find out the relationships among capacity degradation, travel time expectation and variance, best arrival reference point, earliest arrival reference point, cumulative perceived value, and equilibrium network flow. Finally, a numerical example is conducted to analyze the effect of capacity degradation on traveler and traffic equilibrium. |
