摘　　要：为了克服传统感应控制无法区别对待多方向拥堵且拥堵程度不同的交叉口,通过电子警察过车数据,获取车辆在路段上的实测延误,设计了一套基于单车延误的单点交通信号感应控制方法。方法在传统感应控制的框架下,使用单车延误代替车辆间隔作为相位切换的参数,同时采用切换延误阈值的动态更新机制,使得上述方法更能适应拥堵交通状态,尤其是拥堵程度不同的交叉口。通过SUMO多个场景的仿真对比,结果证明用实测延误作为感应控制的切换参数具有明显优势,扩大了感应控制的适用范围。In order to overcome the inability of traditional actuated control to treat the multi-direction congested intersections with different congestion levels differently,the research obtained the measured delay of vehicles on the road section through the data of electronic police passing and designed a set of single-point traffic signal actuated control method based on single delay.In the framework of traditional actuated control,the proposed method used single delay instead of vehicle interval as the phase switching parameter,and adopted the dynamic updating mechanism of switching delay threshold,which makes the method more suitable for the congested traffic conditions,especially for intersections with different levels of congestion.The simulation results of SUMO show that the measured delay as the switching parameter of actuated control has obvious advantages and expands the application range of actuated control.
