Nowadays, an express/local mode has be studied and applied in the operation of urban rail transit, and it has been proved to be beneficial for the long-distance travel. The optimization of train patterns and timetables is vital in the application of the express/local mode. The former one has been widely discussed in the various existing works, while the study on the timetable optimization is limited. In this study, a timetable optimization model is proposed by minimizing the total passenger waiting time at platforms. Further, a genetic algorithm is used to solve the minimization problems in the model. This study uses the data collected from Guangzhou Metro Line 14 and finds that the total passenger waiting time at platforms is reduced by 9.3%. The results indicate that the proposed model can reduce the passenger waiting time and improve passenger service compared with the traditional timetable.

快速/本地模式的城市轨道交通时刻表优化模型

如今，已经研究了一种快速/本地模式，并将其应用于城市轨道交通的运营中，并已被证明对长途旅行是有益的。在快速/本地模式的应用中，火车模式和时刻表的优化至关重要。前一种在各种现有工作中得到了广泛的讨论，而对时间表优化的研究却是有限的。在这项研究中，通过最小化平台上的总乘客等待时间，提出了时间表优化模型。此外，遗传算法用于解决模型中的最小化问题。本研究使用从广州地铁14号线收集的数据，发现在平台上的总乘客等待时间减少了9.3％。
