摘要

在城市地铁系统中,经常会发生突发事件,导致计划时刻表不一致,延误乘客行程。因此,本研究重点关注在非高峰期采用跳站策略重新安排时刻表的问题。此外,现有的一些优化模型都是使乘客的总等候时间最小化,这可能会对在某些车站等候时间较长的一小部分乘客造成公平性问题。在本研究中,提出了一种考虑乘客等候时间公平性和列车旅行时间成本的重新安排模型。该模型通过南京地铁二号线随机设计的延误场景进行了测试,并通过基于分解法设计的迭代算法进行了有效求解。结果表明,与标准停车模式相比,跳站模式能更好地缓解突发延误的影响,同时保证乘客候车时间的公平性。

Metro stop-skipping rescheduling optimization considering passenger waiting time fairness
In urban metro systems, unexpected events often occur to cause discordance in the planned timetable and delay in passenger travel. Therefore, this study focuses on the timetable rescheduling problem by adopting a stop-skipping strategy during the off-peak period. In addition, there are a number of existing optimization models that minimize the total passenger waiting time, which can cause fairness issues for a small group of passengers having longer waiting time at some stations. In this study, a rescheduling model is proposed to consider passenger waiting time fairness and train travel time cost. This model is tested with a randomly designed delay scenario of Nanjing Metro Line 2, which can be efficiently solved by a designed iterative algorithm based on decomposition method. Compared to the standard stop pattern, the result shows that the stop-skipping pattern can better alleviate the impact of sudden delays, while simultaneously ensuring the passenger waiting time fairness.

期刊介绍: Transportation Letters: The International Journal of Transportation Research is a quarterly journal that publishes high-quality peer-reviewed and mini-review papers as well as technical notes and book reviews on the state-of-the-art in transportation research. The focus of Transportation Letters is on analytical and empirical findings, methodological papers, and theoretical and conceptual insights across all areas of research. Review resource papers that merge descriptions of the state-of-the-art with innovative and new methodological, theoretical, and conceptual insights spanning all areas of transportation research are invited and of particular interest.
