由于北京人口密度极大,地铁系统运能在部分时段显不足。针对如何在现有的硬件基础上提高北京地铁的运能、如何将运能的利用率提高等问题展开了研究。通过采集北京地铁的相关数据,发现同一列车的不同车厢乘客人数有着较为明显的差异:中间车厢乘客人数较少,而两端车厢人数较多。此外,通过对不同车站平面的简要分析,发现大多数楼梯出口都设置在靠近列车两端车厢位置,在某种程度上影响了乘客在进入站台时对不同车厢的选择。这一系列现象在一定程度上造成了运能的浪费,也影响了乘客的舒适度。为解决上述问题,参考了国内外各个城市在这方面成功案例,对北京地铁系统提出了包括高峰时段安排少座(或无座)车辆上线运营、设置隔离栏、媒体宣传等的一系列改进建议。 Due to the great population density in Beijing, the transportation system of the MTR system is not enough in some time. Aiming at how to improve the transportation capacity of Beijing subway based on the existing hardware and how to improve the utilization rate of transportation capacity, Through collecting relevant data of Beijing Subway, it is found that there are obvious differences in the number of passengers in different cars on the same train: the number of passengers in the middle compartment is relatively small, while the number of cars on both ends is relatively large. In addition, through a brief analysis of different stations ’planes, it is found that most of the stair exits are located close to the train compartments at both ends of the train, to a certain extent, affecting the passengers’ choices of different compartments when entering the platform. This series of phenomena to a certain extent caused by the waste of transport capacity, but also affect the comfort of passengers. In order to solve the above problems, reference is made to the success stories of cities in China and other countries in this respect. A series of suggestions for improving the Beijing metro system are put forward, including the operation of a few seats (or no seats) on the subway during peak hours, setting up fences and media campaigns .
