The invention discloses a traffic signal control method. The method comprises the steps of dividing a research area into a plurality of control subareas, and determining an intersection of each control subarea; establishing a double-layer optimization model; calculating the phase pressure of each intersection of each control subarea according to the vehicle distribution of the research area; whenthe maximum phase pressure in the phase pressures of all the intersections is greater than an activation phase, determining a traffic signal control scheme when the total output vehicle number of theresearch area at the K moments after the current moment is maximum and the quadratic sum of the difference between the vehicle number of each control subarea at the K moments after the current momentand the optimal vehicle number is minimum by adopting the double-layer optimization model. According to the invention, the research area is divided into a plurality of control subareas, and the boundary signal lamp of each control subarea is optimized, thereby achieving the optimal control of the traffic in the area, and avoiding the defect of local congestion in the area.

    本发明公开了一种交通信号控制方法,所述控制方法包括如下步骤:将研究区域划分为多个控制子区,并确定每个控制子区的交叉路口;建立双层优化模型;根据研究区域的车辆分布计算每个控制子区的每个交叉口的相位压力;当所有的交叉口的相位压力中的最大的相位压力大于激活相位时,采用双层优化模型,确定当前时刻后的K个时刻的研究区域的总输出车辆数最大时,且当前时刻后的K个时刻的每个控制子区的车辆数与最优车辆数差的平方和最小时的交通信号控制方案。发明将研究区域划分为多个控制子区,对于每个控制子区的边界信号灯进行优化,实现了区域内的交通的优化控制,避免了区域内的局部拥堵的缺陷。
