考虑滞站调度的有轨电车信号优先控制策略研究

Research on the tram signal priority control method considering the holding strategy

在有轨电车主动式信号优先控制系统的基础上,提出站台控制方式(即刻离站或滞站调度)与交叉口信号优先控制方式(绿灯提前、绿灯延长、相位插入等)组合的控制策略。并建立以整体延误损耗为基础的交叉口效益函数,分析比较各组合控制策略与滞站调度控制策略效益值的大小,选择效益最优的有轨电车优先控制策略。最后针对组合控制策略在交叉口进行实例应用。该组合控制策略在保证有轨电车优先权的同时,也降低了其在站台的停靠时间这一不确定因素对调度系统和信号优先系统的影响。

Based on the active signal priority control system, a combined control strategy based on the platform control mode （immediate departure or holding） and the intersection signal priority （early green, green extension, phase insertion, etc.） is established in this paper. And a benefit model with the total delay is proposed, the magnitude of the benefit value between the combined control strategy and the holding strategy for an optimum solution is compared. Finally, an example is given to make the tram get its priority, and the influence of the uncertainty of the tram＇s stop time is also reduced in scheduling system and signal priority system.
