System for controlling intersection traffic and leading current direction

Abstract

The invention relates to a system for controlling intersection traffic and leading current direction, which comprises a central control unit, a local signal acquisition unit, a remote signal acquisition unit, a traffic light control unit and a travel direction control unit, wherein the central control unit is connected with a parameter setting input device; the local signal acquisition unit is used for acquiring vehicle travel condition signals of each driveway; the remote signal acquisition unit is used for receiving remote signals; and the central control unit performs optimization computation of traffic control under the support of a preset program, automatically generates traffic light control mode parameters and driveway travel direction mode parameters in corresponding states, and controls the operating states of traffic lights and the display states of driveway travel direction displays. According to traffic conditions of different road sections and roadways, the system can automatically adjust control parameters of the traffic lights and automatically adjust the travel direction of each driveway at an intersection so as to improve the overall traffic capacity of the intersection and urban roads.

Description

technical field [0001] The invention relates to an intersection traffic control and flow direction dredging system, which controls the traffic flow at different intersections by controlling the state of traffic lights and the driving direction of lanes, so as to dredge the traffic flow, alleviate the traffic pressure on congested roads and congested road sections, and effectively utilize road resources. technical background [0002] The driving direction of each lane at the existing road intersection is limited by the traffic signs on the ground, so 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 have serious When traffic congestion occurs, the flow 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 shorte...

[0002] The driving direction of each lane at the existing road intersection is limited by the traffic signs on the ground, so 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 have serious When traffic congestion occurs, the flow 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. Traffic capacity, causing vehicles in the corresponding lane to wait in line for a long time before entering the intersection, causing new congestion
