交叉口处现代有轨电车与其他机动车的平衡感应信号控制方法

介绍了现代有轨电车与机动车在交叉口的平衡感应信号控制方法,通过对现代有轨电车交叉口各入口排队车辆数的监测,实时改变信号配时,从而平衡各入口车辆排队长度;通过赋予现代有轨电车更高的排队权重,使现代有轨电车与同向机动车流减少停车时间,获得更多的通行时间,从而在保证其他机动车辆通行效率的同时,间接地实现现代有轨电车优先通行权。运用交通仿真软件对比分析各入口车辆平均排队长度、最大排队长度、总停车次数、平均延误与平均排队时长,确定各信号相位近似最优的最大感应绿灯信号时长。仿真结果表明,在排队长度与车辆延误方面,感应信号配时远优于定时信号配时;相比单纯的公共交通信号优先,感应信号控制更注重现代有轨电车和机动车每个乘客的通行权利。

Equalized Actuated Signal Control for Modern Trams and Moter Vehicles at Intersection

The equalized actuated signal control for modern trams and moter vehicles at intersection is introduced.The signal timing is changing over the detection of the number of approaching vehicles at a tram intersection in order to balance vehicle queue length at each approach.By assigning a higher queuing weight to the tram,the stopping time of the approaching trams and motoer vehicles on the same direction is reduced and more passing time is provided.As a consequence,the tram enjoys indirectly a transit priority without increasing the delay time of motor vehicles,and the passing right for both trams and vehicles is equalized.By studying the average vehicle queue length,the maximum vehicle queue length,the total vehicle stopping time,the average vehicle delay time and the average vehicle stopping time,an approximate optimal maximum actuated green time is confirmed.By analyzing the output of a traffic simulation software,the equalized actuated signal control outperforms the optimal fixedtime control in respect of vehicle queue length and vehicle delay time.In comparison with aggressive transit signal priority,the equalized actuated control focuses more on every passenger's passing right.
