The invention discloses a regional anti-overflow traffic signal control game method and system. The method comprises the steps: acquirig a road segment attribute parameter and a node attribute parameter in a control region, determining a detection region on the control region, and enabling the road segment attribute parameter to comprise an associated traffic flow; acquiring vehicle data in two adjacent detection regions, comparing the vehicle data with a preset road segment overflow threshold value, and acquiring a road segment overflow state level soi at the current moment; according to theroad segment overflow state level soi, constructing an equilibrium target function based on the associated traffic flow, and obtaining a mixed integer linear programming model of a regional anti-overflow signal control strategy game; carrying out calculation according to the mixed integer linear programming model to obtain a passage right distribution strategy of each turning direction in an intersection, realizing a passage right distribution strategy through single-point and coordination signal control, and achieving anti-overflow control of regional traffic flow; self-adaptive control overoverflow prevention of regional signals is achieved, and the road network operation pressure is relieved.

    本发明公开了一种区域防溢出的交通信号控制博弈方法及系统,包括:获取控制区域中的路段属性参数和节点属性参数,确定所述控制区域上的检测区域,所述路段属性参数包括关联交通流;获取相邻两检测区域中的车辆数据,将车辆数据与预设的路段溢出阀值进行比较,获取当前时刻的路段溢出状态等级so;根据路段溢出状态等级so,构建基于关联交通流的均衡目标函数,得到区域防溢出信号控制策略博弈的混合整数线性规划模型;根据混合整数线性规划模型求解得到路口内部各转向的通行权分配策略,通过单点和协调信号控制实现通行权分配策略,达到区域交通流的防溢出控制;实现了区域信号防溢出的自适应控制,缓解路网运行压力。
