摘　　要：提出一种改进的感应信号控制算法,并以交叉口平均车辆延误以及平均排队长度作为评价控制算法的指标,采用Paramics为仿真软件;将该算法与传统感应信号控制算法及Synchro 7优化的定时控制方案进行仿真对比。仿真结果表明提出的算法改进效果十分显著,尤其是当交叉口交通流量较大、饱和度较高时,传统算法已经没有改进效果,而该算法改进效果依然显著。This paper proposes an improved actuated signal control algorithm and uses average vehicle turn delay and average queue length to evaluate the control algorithm.Base on Paramics,it simulates the proposed algorithm in comparison with traditional actuated signal control algorithm and fix-time control algorithm optimized by Synchro 7.Simulation results prove that the improvement of the proposed algorithm is significant,especially when the traffic volume is heavy and the saturation is high,the proposed algorithm is still outstanding while the traditional algorithm has no improvement.
