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

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.
