Coordinated trunk line planning method and configuration system based on traffic flow data

Abstract

The invention provides a coordinated trunk line planning method and configuration system based on traffic flow data, Integrating the Internet data and the passing data of the video number plate identification device, and relying on the traffic flow data in the non-congestion period to determine the key direction, so as to identify and configure the coordination direction of each control period, and then planning and configuring the coordination trunk line; The invention recognizes the non-congestion time period based on the traffic state data of the Internet, By analyzing the trunk configuration in this time period, the problem of low efficiency of coordination trunk caused by traditional trunk configuration according to network traffic planning and considering the coordination direction of each intersection for saturated time period and unsaturated time period is avoided, thus the accuracy of coordination trunk in different time periods is improved, and the coordination optimization is achieved. The invention identifies and analyzes the configuration of the trunk lines in different time periods, improves the implementation efficiency of the coordination trunk lines, and provides auxiliary support for the coordination and optimization of the regional signals.

Description

technical field [0001] The invention relates to a coordination arterial route planning method and configuration system based on traffic flow data. Background technique [0002] In urban roads, intersections are relatively close to each other. When single-point signal control is set at each intersection, vehicles often encounter red lights and stop and drive from time to time, resulting in poor traffic and aggravating environmental pollution. Therefore, in order to make vehicles To reduce the parking time at various intersections, it is necessary to connect a group of adjacent traffic signals on an arterial line for coordinated control. At present, with the increasing number of motor vehicles, the problem of traffic congestion is becoming more and more serious, the traffic signal control system is being popularized constantly, and the traffic police departments at all levels have begun to implement arterial lines on the main roads of the city. [0003] At present, the coordi...
