Intersection control machine capable of shortening green light lost time and control method

Abstract

The invention provides an intersection control machine capable of shortening green light lost time and a control method. Detectors with the video tracking function are used for continuously tracking all vehicles passing an intersection, the time for each vehicle to reach an intersection stop line at a current speed can be accurately detected, when vehicles come from two directions at the same time, the vehicles which reach the stop line first can be accurately measured under the current road traffic conditions, on the premise that the current speeds of the vehicles in the two directions are kept, a green light signal can be preferentially provided for the vehicles which reach the stop line first, and the efficiency of the green light is improved. According to the technical scheme of the intersection control machine, the problem caused by the mode that only one or more detectors can be embedded in the cross section, nearby the intersection stop line or with a certain distance from the intersection stop line, of the intersection is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an intersection control machine and a control method capable of reducing the lost time of green lights. Background technique [0002] The intersection traffic signal control machine is an effective method to standardize the traffic order at intersections, prevent and reduce traffic accidents caused by disorderly intersections, and improve the efficiency of intersection traffic. Domestic and foreign traffic management departments generally use traffic signal controllers to control the orderly transformation of red, yellow and green lights at intersections where urban traffic volume changes greatly to regulate the order of intersection traffic. [0003] When people drive to an intersection controlled by signal lights, they all hope that they will not stop when they encounter a green light. This is impossible when the traffic in all directions at the intersection ...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the problem that in the prior art, the intersection traffic signal cannot accurately give the green light signal to the vehicle that first arrives at the stop line direction, and often gives the direction where there are no vehicles and pedestrians, resulting in the loss of green light time, thereby providing a Intersection control machine capable of reducing green light loss time and control method
