摘　　要：通过考虑柔性车道设置,针对带有左转专用相位的公交优先十字交叉口,结合预信号系统进行车辆和行人延误分析。在交叉口某一进口道采用该设计,分析主信号和预信号处车辆到达和离开过程,对采用柔性车道设置前后的公交车、直行社会车辆和左转车辆的延误变化进行计算。结果表明:在带有左转专用相位的公交优先十字交叉口某一进口道采用柔性车道设置后,当交叉口处于饱和状态时,公交车辆延误显著减少,左转车辆延误和直行车辆人总延误皆有所减少。By considering the flexible lane setting, the vehicle and pedestrian delay analysis is carried out for the bus priority intersection with left-turn phase, combined with the pre-signal system. The design is adopted at an intersection to analyze the arrival and departure process of vehicles at the main signal and presignal, and calculate the delay changes of buses, straight social vehicles and left-turn vehicles before and after flexible lane setting. The results show that after a flexible lane setting is adopted at an entrance of a bus priority intersection with a left-turn phase, when the intersection is saturated, the bus delay is significantly reduced. The delay of left-turn vehicles and the total delay of straight vehicles are both reduced.
