Example Embodiment

[0016] figure 1 This is a schematic block diagram of the traffic light control system of the present invention. The system includes a vehicle detection device, a controller module, an arithmetic unit module and a traffic light. The vehicle detection device and the traffic light are both connected to the central control device. The vehicle detection device is an infrared counter, which includes a transmitter Receiver, a receiver that blocks the reception of infrared rays when the vehicle passes, and the counter is incremented or decremented by one. A car starting area is reserved at the intersection from east, west, north, south, south, and four oncoming traffic directions, and a vehicle detection device is respectively provided on the through lane and the left-turn lane at the entrance of the vehicle starting area. A vehicle detection device is respectively provided on the straight-through lane and the left-turn lane at the exit of the vehicle starting area. Detects vehicles ...

Abstract

The invention discloses a traffic light control system and a traffic light control method. The control system comprises vehicle detection devices, a central control device, an arithmetic unit module and a traffic light, wherein the vehicle detection devices are connected with the arithmetic unit module; and the traffic light is connected with the central control device. The control system is characterized in that: an automobile starting area is formed at each intersection in a vehicle coming direction; when encountering a red light, an automobile stops outside the automobile starting area; the vehicle detection devices are arranged at the entrance and the exit of the automobile starting area; and the automobile starting area is formed, so that automobile starting time is saved and traffic jam is prevented.

Description

technical field [0001] The invention relates to a traffic light control system and method. Background technique [0002] Due to the increase in the number of vehicles and the relatively backward level of traffic management, congestion often occurs at traffic intersections. The original traffic control system is mainly a timing system. The timing system cannot adjust the traffic flow in all directions according to the real-time road conditions. This kind of traffic lights is low in cost and widely used. However, because this system cannot adjust the traffic flow according to the real-time road conditions, it is easy to cause traffic jams. Contents of the invention [0003] Aiming at the defects existing in the prior art, the present invention provides an optimized traffic light system control system and method, which can save the start-up time of the car, and can automatically adjust the traffic lights at each intersection according to real-time road conditions. Effectivel...
