摘　　要：文中通过在交叉口进口道上布设检测器,由检测数据计算得到处于红灯状态下的机动车相位对应的绿灯需求度,通过对比相位绿灯需求度的大小,优化下一相位的选择,提出一种跳相序的相位选择方法.并运用VISSIM对武汉市团结大道—园林路交叉口分别采用NEMA双环相位结构控制策略和文中感应控制策略后的运行状况进行了仿真模拟对比分析.仿真结果表明:在流量均衡场景下,NEMA控制策略较优,但两者延误相差不大;在流量不均衡和特殊流量下,文中控制策略较优,特别是在流量不均衡和特殊流量场景下的高饱和度交叉口,控制策略都具有明显的优势.The detector was arranged on the entrance road of intersection,and the green light demand degree corresponding to the motor vehicle phase in the red light state was calculated from the detection data.By comparing the green light demand of phase and optimizing the next phase selection,a phase selection method of phase skipping sequence was proposed.By using VISSIM software,the running status of Tuanjie Avenue-Yuanlin Road intersection in Wuhan after adopting NEMA double-loop phase structure control strategy and induction control strategy in this paper was simulated and compared.The simulation results show that NEMA control strategy is better in the traffic balance scenario,but there is little difference in delay between them.Under unbalanced and special traffic conditions,the proposed control strategy is superior,especially at high saturation intersections under unbalanced and special traffic conditions.
