Regional intersection traffic control method and system based on edge calculation

Abstract

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.

Description

technical field [0001] The present application relates to the field of intelligent transportation technology, in particular to a method and system for traffic control at regional intersections based on edge computing. Background technique [0002] With the rapid development of society and economy, the number of automobiles in our country has increased rapidly year by year, and the daily road traffic management work has become very heavy, which has become an urgent problem to be solved in the traffic management department. [0003] At present, in the case of traffic peak or special service, the following methods are generally used to control the traffic at the intersection: first, through the traffic police at the intersection according to the traffic flow of the branch road entrance, to artificially guide the incoming vehicles; Phase green light time to control traffic flow and prevent congestion. [0004] However, when the traffic management personnel are on duty at the sc...
