摘　　要：研究了交通拥堵时段的优化控制问题。提出一种二级防冲突相位控制算法的交通拥堵调控方案。根据复杂路况,建立两相位的车辆排队长度和变化量,确定二级相位的交通紧张度;根据不同相位的道路紧张程度,确定时域内的多点控制条件,保证调节效率。仿真结果显示,二级防冲突控制算法有效地降低了车辆平均延误时间,提高了交通运行效率。Study the optimal control in the period of traffic congestion. The paper put forward a traffic congestion control scheme of twe-level anti-collision phase control algorithm. According to the complex road conditions, it set up two phases of vehicle queue length and its variation to determine the phase two-level traffic congestion. According to different road congestion, it determined more control conditions in the time domain to ensure the adjust efficiency. The simulation results show that the twe-level anti-collision control algorithm is effective to reduce the average vehicle delay time and improve the operation efficiency of traffic.
