Whole-journey independent phase green wave induction control method and system of traffic flow

Abstract

The invention relates to a whole-journey independent phase green wave induction control method and a system of traffic flow, belonging to the technical field of traffic signal control. The method comprises the steps of: setting vehicle sensors and waveband signal indicator lamps along a road, setting parallel road induction stream signal indicator lamps and buffering yellow waveband signal lamps at intersections, transmitting a traffic flow signal and a green wave band control signal in a wireless manner, transmitting a traffic flow pulse signal to a computer for processing and pre-grouping the traffic flow, emitting a pre-grouping signal command, periodically turning on the waveband signal indicator lamps along the road to form a movable green wave band so as to guide the vehicles to travel and group the traffic flow, and matching the intersection signal lamps to realize whole-journey independent phase green wave induction control of the traffic flow. The system comprises a traffic flow signal collecting, traffic flow signal processing and controlling device, intersection signal lamps and control cabinets of the intersection signal lamps, the vehicle sensors and the waveband signal indicator lamps are arranged along the road, and the sensors and the indicator lamps are in wireless connection with the signal processing and controlling device. The method and the system, disclosed by the invention, have the advantages of realizing phase difference independent green wave band induction of vehicles and improving the intersection passing efficiency, etc.

Description

technical field [0001] The invention relates to a whole-process independent phase green wave traffic flow induction control method and system, belonging to the technical field of traffic signal control. Background technique [0002] With the continuous development of cities and the continuous increase of vehicles, traffic congestion has become the most troublesome thing in modern society. Traffic management has attracted more and more attention. Urban road networks are basically composed of road sections and intersections. As far as road sections are concerned, intersections have a greater impact on the traffic capacity of urban roads and are the bottleneck of urban traffic flow, while signalized intersections are a more critical link in the urban road network. Most of the existing urban road intersection signal control cycles use historical data as the basis. This historical statistical data cannot reflect the dynamic and real-time traffic flow status, and cannot effectivel...
