Traffic light interval time automatic adjusting system and method

Abstract

The invention provides a traffic light interval time automatic adjusting system and method. The method comprises the following steps that a camera collects vehicle information corresponding to a laneand sends the vehicle information to a processing unit; the processing unit analyzes the received vehicle information, and re-determines duration information corresponding to a red light and a green light in traffic signal lights according to an analysis result; and the processing unit controls a period interval of the red light and the green light to be adjusted to a corresponding period intervalin the duration information through a signal light duration control unit. By real-time collection of the vehicle information in each lane direction, automatic adjustment of the traffic light intervalis achieved, so that the duration of the green light can be prolonged in time when traffic jam occurs on a certain lane, the vehicle flow of vehicles passing in a unit traffic light period can be conveniently increased, the traffic jam condition is effectively relieved, and the possibility of causing large-range traffic paralysis is reduced.

Description

technical field [0001] The invention relates to the field of adjusting traffic lights, in particular to a method and system for automatically adjusting the interval time between traffic lights. Background technique [0002] With the rapid growth of vehicle ownership, congestion has become an important social problem. In the current traffic management system, the vast majority of intersections use the traffic light system for traffic command, and the vast majority of traffic lights are controlled through preset programs. The mismatch between the design of traffic light traffic patterns and passing time and actual road conditions has become a traffic issue. One of the important causes of congestion. The existing traffic light control system cannot conduct real-time analysis of the real-time traffic conditions at the intersection, and quickly adjust the traffic mode or the traffic time of traffic lights in different directions, and then strive to direct traffic at all intersec...

AI Technical Summary

Problems solved by technology

[0004] To this end, it is necessary to provide a technical solution for automatic adjustment of the interval between traffic lights to solve the problem that the existing traffic light control system lacks the linkage control of traffic lights related to the direction of congestion, which easily leads to the accumulation of traffic congestion in a single direction, resulting in large-scale traffic paralysis. question
