The invention discloses a self-adaptive signal coordination control method for a shift left-turn intersection, and the method comprises the steps: firstly determining a signal phase sequence based on the coordination control of a main intersection and a pre-intersection; initializing the signal period of the intersection and the green light duration of each phase according to the historical traffic flow of the intersection; predicting a short-term traffic flow arrival condition of each entrance of the intersection; and finally, by taking the minimum average delay of the vehicles passing through the intersection as a target, constructing a signal period optimization model, and solving to determine the optimal green light time in the signal period so as to realize target optimization. According to the invention, self-adaptive coordination signal control of the shift left-turn intersection can be completed, and the operation efficiency of the intersection is greatly improved.

    本申请公开了一种移位左转交叉口的自适应信号协调控制方法,先以主预交叉口协调控制为基础,确定信号相位相序;根据交叉口的历史交通流量,初始化交叉口的信号周期以及各个相位的绿灯时长;预测交叉口各进口的短期交通流到达情况;最后以通过交叉口的车辆平均延误最小为目标,构建信号周期优化模型,并求解以确定信号周期内最优化的绿灯时间,实现目标最优。本申请能够完成移位左转交叉口的自适应协调信号控制,极大程度提高交叉口运行效率。
