Intelligent traffic light controller based on video vehicle queue length detection and control method thereof

Abstract

The invention discloses an intelligent traffic light controller based on video vehicle queue length detection and a control method thereof, and provides a traffic light controller and method which are low in cost and can adjust traffic light time intervals automatically in various types of road junctions according to vehicle queue waiting condition on the road surface. Besides, road waiting vehicle queue length detection is performed by virtue of existing road cameras and a video analysis technology, and the traffic light time intervals are adjusted dynamically according to detection results of multiple waiting lanes. During construction, all that is needed is to mount a small-size control box on each road junction, the mounting cost is reduced greatly, and the construction scale is reduced; the controller and the method have wider application; and the duration of the traffic lights can be automatically controlled according to the vehicle queue length of each waiting lane in real time, manual adjustment is not needed, the road passage efficiency can be improved effectively, the traffic jam condition of crossroads can be relieved, and the normal passage of vehicles and pedestrians is guaranteed.

Description

technical field [0001] The invention relates to a traffic light intelligent controller and a method thereof in the field of intelligent transportation, which are applied to road traffic management. Background technique [0002] At present, intelligent traffic light signal control technology has been proposed by more and more people as an important technology in the field of intelligent transportation and applied to new road traffic management models. Different from the traditional fixed-period traffic light control mode, the new signal light control mode can dynamically adjust the time interval of traffic lights according to the actual road conditions, so as to avoid vehicles in one direction of the intersection waiting for the red light and being too congested while other directions But idle green light time and so on. [0003] Most of the existing intelligent traffic light signal control technologies use equipment such as ground pressure sensors and loop coil detectors. ...

AI Technical Summary

Problems solved by technology

However, this solution is only applicable to simple intersections. When the intersection includes left-turn control, it may occur that the green light time of a certain phase is too long and the green light time of the next phase with the same congestion is very short, resulting in traffic management problems. mistake
