摘要:
有轨电车信号主动优先策略仍存在旅行速度与运营效率较低的问题。针对运行在城市干道上的路中式有轨电车线路，从站台位置布设、干线协调控制、建议速度计算、系统设计与实现等方面进行研究；通过控制有轨电车速度来保证绿波带的实现；采用离线速度计算方法，生成时刻速度表，通过查询方式代替速度实时计算，降低了信号优先系统的复杂度，提高了实时性。采集实际数据，利用VISSIM软件进行仿真试验。试验结果表明：基于速度控制的信号优先系统可显著提高有轨电车的旅行速度。
Abstracts:
Although most of modern tram lines built in China implement signal priority, there are still problems in low traveling speed and operational efficiency. Focusing on tram line running in the middle urban trunk road, the station location layout, trunk coordination control, recommended speed calculation, system design and implementation are mainly researched. Through controlling the tram speed, the green wave band is realized, by adopting the offline speed calculation, the time\|speed table is generated, and by using the query method to replace the speed real\|time calculation, the system complexity is reduced and the real\|time performance is improved. On this basis, a simulation test is conducted by using the practical data and VISSIM software. The result shows that the signal priority based on speed control could increase the tram travel speed obviously.
