基于信息实时交互的现代有轨电车信号优先控制研究

On Signal Priority Control of Modern Tram Based on Real-time Information Interaction

现代有轨电车优先通行的关键在于对路口交通的处理,通过连续设置有轨电车检测器,实时获取有轨电车通行的位置信息,实现有轨电车信号控制器和道路交通信号控制机之间的信息实时交互。基于交互信息的类型,设计优先控制流程和控制方式,实现现代有轨电车的主动优先控制。应用结果表明,现代有轨电车路口不停车通过率达到86.02%,平均速度由原先的21.7 km/h提高至25.6 km/h,有效地提高了现代有轨电车路口通行效率。

The key to the priority pass of modem tram is the traffic capacity at intersections. Through continuous setting of tram detectors,the real-time location information of tram access is collected,the information interaction between tram signal controller and road traffic signal controller is achieved. Based on the types of information interaction,the design of priority control flow and control mode, the active priority control of modem tram is realized. Actual results show that the application of this method has increased the non-parking pass rate to 86.02%,the average speed increased from 21.7 km/h to 25.6 km/h,and the priority traffic efficiency of modern tram proves significant.
