锯齿形公交优先进口道的设计与延误分析

Design and analysis of delay on indented bus priority approach

根据锯齿形公交优先进口道的工作原理和工作流程,分析了公交候驶区的长度和主、预信号的信号配时,并采用V ISS IM仿真软件,对交叉口进行仿真,分析在设置锯齿形公交优先进口道前后,交叉口的交通延误变化情况。结果表明:通过设置锯齿形公交优先进口道,公交车辆的车均延误减少,社会车辆的车均延误增加,但是乘客总延误和人均延误都减少了,改善了整个交叉口的交通运行状况。

To realize the bus priority at intersection, the design of exclusive bus lane approach is researched in this paper and the method of indented bus priority approach is used. According to the work principle and work process of indented bus priority approach, the length of bus advanced area and the timing of pre-signal and main signal are analysed. And the intersection is simulated by VISSIM, the traffic delay variety of intersection is analysed with and without indented bus priority approach. It shows that the delays of public vehicles are reduced and those of social vehicles are increased by setting indented bus priority approacho but the total and average passenger delays are reduced, thus it improves the operating situation of the entire intersection.
