北京市南中轴路快速公交运营效果分析

An Operational Analysis of the BRT System along Beijing South-Central Corridor

在介绍北京市南中轴路快速公交概况的基础上,从常规公交线路调整和交叉口信号优先两方面阐述了南中轴路快速公交实施的保障措施,并且从道路交通系统、公交服务水平和乘客满意度三方面具体分析了BRT的运营效果。同时,通过对比BRT与轨道交通,得出了BRT较明显的优势。最后,针对规划和运营中存在的问题提出了相应的改进建议措施,如组织编组运营、加快高峰时间的车辆周转、加开大站快车、加开区间车和尽快投入超大容量车型等措施,并对建设与运营提出了一些思考。

Through a background introduction of Beijing SouthCentral BRT system, this paper discusses measures that ensure a normal operation of the system by adjusting routine bus lines and offering signal priority for buses at intersections, and analyzes the system operational effects in terms of road traffic characteristics, bus LOS as well as passenger satisfaction. A comparison between the BRT system and rail transit shows that the former prevails significantly. The paper also discusses the existing problems within the system and improvement suggestions or some thoughts regarding the construction and operation of the system. These include bus-grouping operation, higher frequency operation during peak hours, express bus services at primary stations or along high-demand corridors, and provision of super-capacity buses as soon as possible.
