Abstract

The invention discloses a traffic light control system. Each vehicle-mounted GPS module locates a lane where a vehicle is located according to the location of the vehicle and transmits the location information to a vehicle-mounted controller, and a vehicle-mounted wireless sending module connected with the vehicle-mounted controller sends the location information out. A wireless receiving module receives the geographic location information sent by the multiple vehicle-mounted wireless sending modules. A traffic light control processor receives the geographic location information acquired by the vehicle-mounted wireless receiving module. The traffic light control processor judges the number of vehicles on each lane through location information calculation and statistics according to the number of vehicles requesting to pass on different roads, acquires the instant passing time by a table look-up method, and drives traffic lights through a traffic light drive circuit to change the time of traffic light signal switching at intersections. The command function of traffic lights can be improved effectively, traffic congestion is alleviated, the utilization rate of roads is improved, and adaptive control on traffic lights is achieved.

Description

technical field [0001] The invention belongs to the technical field of traffic, and relates to a traffic light control system. Background technique [0002] At present, the time switching of existing traffic lights is fixed time, this inflexibility will cause the cars on some roads at some intersections to be congested and anxiously waiting for the green light, while other lanes at the intersections There is very little traffic on the road and too much green light time is given, resulting in low utilization of road traffic and accelerating traffic jams. The fixed traffic light time of this control is extremely unreasonable, and it is easy to cause traffic congestion, blockage, and even traffic accidents. Contents of the invention [0003] The purpose of the present invention is to provide a traffic light control system, which solves the problem that the time of traffic lights at intersections is fixed and cannot be adjusted in real time due to the traffic flow of roads in...
