摘　　要：为了对城市交叉口交通溢流现象进行管控,利用MCU-6智能信号控制器与地磁检测器结合,实现信号周期相位实时控制,以达到限制溢流方向的车辆通行,优先放行非溢流方向车流的目的。以北京市成府路-中关村东路交叉口交通溢流为例开展了VISSIM仿真和实地实验的验证,结果表明:利用反溢流控制可以提高交叉口交通量、减少排队延误、缩短车辆通过时间、降低交通溢流发生频率及严重性,从而提高交叉口整体通行效率。In order to control the traffic spillover of urban intersections, in this paper a metlaoci is proposed to real timely control the signal cycle by combining MCU-6 intelligent signal controller with magnetic detector. The purpose of this control method is to restrict traffic of spillover direction, while giving priority of other directions. With the intersection of Chengfu Road and Zhongguancun East Road as the case, verifications are made by VISSIM simulation and field experiment. Validation results show that anti-control of traffic spillover are capable of increasing traffic volume, decreasing traffic waiting delay, through time as well as traffic spillover frequency and seriousness, and then improving traffic efficiency.
