Intelligent traffic light system

Abstract

An intelligent traffic light system disclosed by the invention relates to the field of signal lights. The problem that vehicles needing to pass wait for the red light to change for too long while there are no vehicles on the road in the green light direction is solved. The key points of the technical scheme are as follows: the intelligent traffic light system includes an intelligent terminal, a road junction unit and a traffic information center; the road junction unit includes traffic lights and an information acquisition module for acquiring traffic information of a road junction; the traffic information center is coupled to the road junction unit to acquire the current vehicle quantity information within a range of M meters on each road and to find current traffic light control information corresponding to the current vehicle quantity information from a preset corresponding relationship between vehicle quantity information and traffic light control information; and the traffic lights switch the travel time of each road under the control of the current traffic light control information. According to the intelligent traffic light system, the travel time of each road is intelligently switched according to the current vehicle quantity information of the road, so that the length of time required for vehicles needing to pass to wait for the red light to change is shortened, and the fuel consumption of vehicles is greatly reduced.

Description

technical field [0001] The invention relates to the field of signal lights, in particular to an intelligent traffic light system. Background technique [0002] The existing traffic light system (also known as: traffic signal light system) lacks intelligence. The display switching of the red street light system often has nothing to do with the number of cars parked on the driveway. It is often found that there are many cars parked and waiting on the road pointed by the red light; there is no car driving for a long time on the road pointed by the green light, which causes the waiting time for the vehicles that need to pass the red light to be too long, while the road in the direction of the green light is too long. There is no car traffic, causing fuel consumption, wasting time and increasing the emission pollution. There is room for improvement. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent traffic light system, which...
