Traffic light control system with functions of violation snapshot and traffic dispersion

Abstract

The invention relates to a traffic light control system with functions of violation snapshot and traffic dispersion, which comprises a local signal acquisition unit for acquiring local traffic state signals, a remote signal acquisition unit for acquiring remote traffic state signals, a snapshot control unit for controlling a snapshot camera, a traffic light control unit for controlling a traffic light, a travel direction control unit for controlling a driveway travel direction display, and a central control unit for generating a traffic light control command, a traffic travel direction command and a violation vehicle snapshot command according to local and remote traffic state data. The traffic light control system can achieve multiple functions of traffic light control, driveway travel direction control and traffic dispersion, traffic condition monitoring, violation vehicle snapshot and the like, and is helpful to improve the intersection traffic management level and the overall urban traffic management level.

Description

technical field [0001] The invention relates to a traffic light control system with the functions of snapshotting violations and traffic guidance, which is mainly used for traffic light control at intersections of traffic roads, traffic guidance, traffic condition monitoring and snapshots of illegal vehicles. technical background [0002] The traffic light control system on the existing road intersection is independent of the traffic condition monitoring and illegal vehicle capture devices, and is controlled by different electronic control systems. This independent setting method is feasible when the respective functions and structures are relatively simple, but With the expansion of the functions of each control system and the dependence on each other's data, the way of independent setting will more and more cause the duplication of hardware equipment and the complexity of information transmission. The situation needs to set up a panoramic camera to continuously take pictur...

Problems solved by technology

Since the driving direction of each lane entering the intersection is limited by the traffic signs on the ground, it is fixed. When the road sections ahead in different driving directions and the vehicle conditions on different roads are different, especially some road sections or roads appear In severe congestion, the traffic in a certain direction can only be controlled by controlling the time interval of traffic lights, and the number of vehicles entering a certain road section through the intersection can be reduced by shortening the green light time. This control method is not conducive to the full and effective use of road resources, especially road intersections. The traffic capacity of the corresponding lane leads to long queues before entering the intersection, causing new congestion
