Road section pedestrian secondary crossing dynamic traffic signal control method and system

Abstract

The invention relates to a road section pedestrian secondary crossing dynamic traffic signal control method. Aiming at pedestrian secondary crossing in a green wave coordination scene, a brand new logic control design is adopted, motor vehicle flow, motor vehicle headway and pedestrian conditions on roadside and road central safety islands comprehensively considered; motor vehicle crossing requirements, reduction of influence on green wave coordination are well balanced according to pedestrian crossing traffic requirements; pedestrian secondary crossing green lights are dynamically turned on, and the duration of the green lights are dynamically distributed; the influence on main road traffic flow can be reduced,and the safety and efficiency of motor vehicle passing and road section pedestrian secondary crossing are improved. A system for executing the control method is further designed correspondingly. The system can be quickly arranged at a target road position, and timely responds to and executes the designed method to ensure traffic safety.

Description

technical field [0001] The invention relates to a method and system for controlling a dynamic traffic signal for secondary crossing of pedestrians on a road section, and belongs to the technical field of traffic management and control. Background technique [0002] The traffic flow of main roads in cities in my country is heavy. In order to improve the traffic efficiency of main roads, green wave coordination road sections are often set up. Green wave coordination road sections mean that vehicles passing through green wave coordination intersections will pass with green lights, and vehicles do not need to wait for red lights. my country has a large population density, and the urban traffic flow is a mixed traffic flow, especially in areas close to commercial land such as schools and hospitals, where there will be a large number of pedestrians crossing the street at road sections and intersections. When the road section is a green wave coordinated road section, pedestrian cro...

Problems solved by technology

[0004] The existing pedestrian secondary crossing control scheme in the road section is to set fixed signal timing, or pedestrian manual push-button induction to activate the green light for crossing the street. The fixed signal timing cannot meet the dynamic and real-time needs of pedestrians and motor vehicles crossing the street, and the manual push-button induction does not take into account motor vehicles. Traffic demand, and will interrupt the green wave coordination of road sections,
