Intelligent traffic signal control system and method for assisting vehicles to quickly pass intersection

Abstract

The present invention relates to an intelligent traffic signal control system and method for assisting vehicles to quickly pass an intersection. The system comprises a signal lamp unit, a traffic monitoring unit and an intelligent control unit; the intelligent control unit is connected with the signal light lamp signal; the intelligent control unit is connected with the signal lamp unit and the traffic monitoring unit; and the intelligent control unit receives information such as the number of vehicles and the number of congested vehicles in corresponding road segments, obtains the number of effective vehicles that can reach the intersection at the corresponding road segments within corresponding time, and obtains in real time green lamp passage time durations required to be distributed in corresponding passage directions of the intersection. With the system adopted, the real-time traffic conditions of the roads can be optimized as a whole, the problem of the asymmetry of the passage time of vehicles in different directions of the traffic intersection can be solved, and the passage time of the vehicles at the traffic intersection can be shortened as a whole.

Description

technical field [0001] The invention relates to an intelligent signal control system, in particular to an intelligent traffic signal control system and a control method for quickly passing through an intersection. Background technique [0002] With the advancement of science and the continuous improvement of people's living standards, there are more and more private cars, buses, engineering vehicles, etc., thus causing congestion at traffic intersections in some time periods such as peak hours. In the prior art, traffic The cycle of the signal is fixed by the system, and it cannot be adjusted according to the traffic congestion in each direction. Therefore, it will cause great trouble to some specific vehicles. [0003] As we all know, specific vehicles such as police cars, fire trucks, ambulances, engineering rescue vehicles, etc. enjoy the right of way on the road, and ordinary cars will avoid specific vehicles. When the traffic intersection (that is, the red street light...
