The invention relates to the technical field of road traffic signal control, and particularly discloses an intersection signal real-time iterative optimization control method for unbalanced traffic flow. The traffic passing demand of the current signal phase, the historical operation time of the current signal phase, the operation time of the previous signal phase and the vehicle queuing condition of the traffic flow direction corresponding to the next signal phase are obtained in real time; calculating the maximum green light time of the current signal phase according to the traffic passing demand of the current signal phase, the historical operation time of the current signal phase, the operation time of the previous signal phase and the vehicle queuing condition of the traffic flow direction corresponding to the next signal phase; and controlling the operation of the current signal phase according to the maximum green light time. According to the method, the problem of signal induction control failure caused by unbalanced traffic flow among signal phases of the actual road intersection can be effectively solved.

    本发明涉及道路交通信号控制技术领域,具体公开了面向非均衡交通流的交叉口信号实时迭代优化控制方法,包括:在交叉口当前信号相位运行时,实时获取当前信号相位的交通通行需求、当前信号相位的历史运行时间、上一信号相位的运行时间以及下一信号相位所对应的交通流向的车辆排队情况;根据当前信号相位的交通通行需求、当前信号相位的历史运行时间、上一信号相位的运行时间以及下一信号相位所对应的交通流向的车辆排队情况,计算出当前信号相位的最大绿灯时间;依据最大绿灯时间对当前信号相位的运行进行控制。本发明能有效的解决实际道路交叉口各信号相位间非均衡交通流导致的信号感应控制失效的问题。
