在城市道路交叉口应用感应式信号优先控制，是确保城市现代有轨电车节能、环保、舒适与高效优势有效发挥的重要措施． 针对交叉口车辆到达检测器安装位置问题，提出了一种配合现代有轨电车信号优先控制的交叉口检测器位置设计方法． 首先，根据交叉口现代有轨电车的优先控制策略及其到达停车线的时刻分布，将现代有轨电车等候绿灯的情况划分为 7 类，并分别提出了绿灯等候时间的计算方法;其次，以检测器、站点与上游相邻交叉口的位置关系分析为基础，建立了检测器位置的计算模型;最后，应用南京河西新城有轨电车规划资料与现状交通实测数据，对设计方法的有效性与可行性进行了检验．结果表明，该方法实用科学，具有很好的工程应用前景．

The application of the actuated signal control at urban intersections is an important measure to ensure the advantages of modern streetcars in energy saving,environment protection,comfort and efficiency.Aiming at the problem of the installation site of vehicle arrival detectors at intersections,a design method of the detector position is proposed for the modern streetcars with priority control at intersections.First,according to the priority control strategy of the modern streetcars at intersections and their arrival time at stop lines,the situations of the modern streetcars waiting for green lights are divided into seven types,and the calculation methods for the waiting time of green lights are respectively put forward.Next,by analyzing the displacement relationships among detectors,stops and upstream adjacent intersections,a computing model for the detector position is constructed.Finally,the validi- ty and feasibility of the proposed design method are testified by using the planning data and current traffic real-time data of Nanjing Hexi modern streetcars.The results show that the proposed design method is practical,and it has a good prospect for engineering applications.
