摘要：快速公交车站是整个系统的“瓶颈”，是系统服务水平和运营效率的关键，直接体现了设施供给与客流需求的平衡。饱和度是车站规划设计的核心指标，影响着其他各种指标的取值。在明确饱和度定义基础上，阐述快速公交车站饱和度与运能、运营速度之间的关系，提出合理的饱和度指标取值方法，并研究饱和度指标在实际车站设计中的具体应用，对于指导BRT车站的规划设计具有重要的意义。

Abstract: Stations along bus rapid transit (BRT) lines, as the bottlenecks of the whole system, are critical in improving level of services and operational effectiveness of the system, which could impose a direct impact on the balancing of facility-supply and travel-demand. Saturation is one of the key factors in BRT station planning and design, influencing the determination of other parameters. This paper defines first the saturations of BRT stations, and then analyzes the relations among saturation, capacity, and operational speed. By proposing evaluation methods for station saturation, the paper further illustrates how saturation factors can be used in practical design of BRT stations, which is promising in BRT station planning and design.

Keywords: BRT Station; saturation; queuing theory; productivity; capacity; operational speed
