论文摘要
本文提出了一个供应侧不确定性的双层公交网络设计问题。上层问题决定了频率设置，以同时最大化效率和股权度量，这是由总有效旅行成本降低和所有OD对的有效旅行成本的最小降低来定义的。较低级别的问题是基于可靠性的过境分配问题，该问题捕获了供应侧不确定性对乘客选择行为的影响。数量研究表明，1）帕累托前沿可能不会凸出； 2）可以同时提高效率和权益目标； 3）增加频率可能会使股权措施恶化； 4）乘客的风险态度会影响两个目标之间的替代率。
This paper proposes a bilevel transit network design problem considering supply side uncertainty. The upper level problem determines frequency settings to simultaneously maximize the efficiency and equity measures, which are defined by the reduction in the total effective travel cost and the minimum reduction in the effective travel cost of all OD pairs, respectively. The lower level problem is the reliability based transit assignment problem that captures the effects of supply-side uncertainty on passengers route choice behavior.Numerical studies demonstrate that 1) the Pareto frontier may not be convex; 2) it is possible to improve the efficiency and equity objectives simultaneously; 3) increasing the frequency could worsen the equity measure; 4) passengers risk attitude affects the rate of substitution between the two objectives.
