System for automatically adjusting traffic light pass modes or time based on real-time road condition

Abstract

The invention discloses a system for automatically adjusting traffic light pass modes or traffic light pass time based on a real-time road condition. Through analyses on traffic image information acquired by a traffic intersection camera in real time, whether a traffic intersection is at a pass peak or valley time period can be intelligently determined, and the traffic light pass modes designed aiming at different time periods are automatically adjusted. According to pass conditions in different directions of the traffic intersection, traffic light pass time in different directions can be intelligently adjusted. When a congestion occurs in one direction, pass time, of a traffic light at an intersection associated to the congestion direction, in the congestion direction can be automatically adjusted, and the congestion in the specific direction is eased. When the fact that an intersection is completely blocked is determined, an alarm signal can be sent to a traffic command center, and a prompt for sending traffic police to command on site. Through measures, traffic pass efficiency can be greatly improved, and congestions, environmental pollution and other social problems are reduced. The system can reconstruct an existing traffic light system at low cost, and the system has high practicality.

Description

technical field [0001] The invention belongs to a control system, in particular to a control system for automatically and intelligently adjusting the passing mode of the traffic lights or the passing time of the traffic lights in different directions according to real-time road conditions. 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 ...

AI Technical Summary

Problems solved by technology

[0003] The existing traffic light control system, when congestion occurs in a certain direction, lacks the linkage control of traffic lights related to the direction of congestion, so as to reduce the possibility of large-scale traffic paralysis due to the accumulation of congestion in a single direction
