基于V/C比的有轨电车信号优先控制策略

Strategy of Tram Signal Priority Control Based on V/C Ratio

为了使有轨电车与城市道路更加契合,改进了停止线法计算通行能力模型,采用车道组计算形式并增加了有轨电车折减系数。同时提出了基于V/C比的有轨电车信号优先策略制定方法。为验证基于V/C比的信号优先策略制定方法的有效性,设立了对比项,采用基于VisVAP的信号优先控制实现方法进行了验证。仿真结果表明,实行有轨电车信号优先策略是很有必要的,并且基于V/C比的信号优先策略是行之有效的。

In order to make the tram and urban road more suitable, the traffic capacity model calculated by the stop line method was improved by using the lane group and tram reduction factor added. The new method of the tram signal priority strategy based tiveness of the method of the tram signal priority on V/C ratio was proposed. In order to verify the effec- strategy based on V/C ratio. The contrast item was set up, and the implement method of signal priority based on VisVAP was adopted. The simulation results show that the strategy of tram signal priority is practical and necessary, and the strategy of signal priority based on V/C ratio is effective.
