The invention discloses a regional intersection traffic control method and a regional intersection traffic control system based on edge calculation, which are used for solving the problem that traffic congestion is difficult to solve when local manual control and pre-control of green light passing time are carried out on a single intersection. The method comprises the following steps: edge computing equipment determines information of adjacent intersections of an intersection to be controlled; an annunciator receives the traffic flow data respectively corresponding to the plurality of road side units from the intersection to obtain the traffic flow data from the adjacent intersection to the entrance lane of the intersection to be managed and controlled; the edge computing equipment receives the traffic flow data from the entrance lane of the annunciator, and determines the entrance lane with the maximum traffic volume as a main road; the edge computing equipment determines other intersections in the direction of a road intersecting with the main road, and determines green light spare time of the to-be-controlled intersection after all traffic flows of the other intersections pass through; and green light prolonging time of the main road is determined according to the green light spare time, and the turn-on duration of the green light of the main road is prolonged.

    本申请公开了一种基于边缘计算的区域交叉路口交通管控方法及系统,用以解决对单一路口进行局部人为控制和预先控制绿灯通行时间,都难以解决交通拥堵的问题。方法包括:边缘计算设备确定待管控交叉路口的各相邻交叉路口信息;信号机接收来自交叉路口的多个路侧单元分别对应的交通流数据,以得到相邻交叉路口到待管控交叉路口的进口道的交通流数据;边缘计算设备接收来自信号机的进口道的交通流数据,确定交通量最大的进口道作为主干路;边缘计算设备确定与主干路交叉的道路方向上的其他交叉路口,并确定待管控交叉路口在其他交叉路口的车流全部经过后的绿灯空余时间;根据绿灯空余时间,确定主干路的绿灯延长时间,延长主干路绿灯的开启时长。
