Tunnel traffic congestion quick evacuation method and control system

Abstract

The invention discloses a tunnel traffic congestion quick evacuation method and a tunnel traffic congestion quick evacuation control system. According to the tunnel traffic congestion quick evacuation method and the tunnel traffic congestion quick evacuation control system, when a traffic accident occurs in a tunnel, the normal passage of vehicles is disabled, all upstream vehicles arriving at the accident point begin to queue up; a plurality of roads which are just slightly affected by the accident are selected as emergency lanes; N control points are set in the in the queuing length of the queued vehicles, so that the vehicles in the whole road can be segmented into N parts; the queued vehicles pass the accident point intermittently according to the marks of the control points. The control system is composed of a remote control center, a traffic detection unit and a traffic evacuation and guidance unit; the traffic evacuation and guidance unit includes a microwave vehicle detector and a video surveillance camera which are connected with the remote control center; and when the traffic detection unit detects a traffic accident, the traffic evacuation and guidance unit is started. With the tunnel traffic congestion quick evacuation method and the tunnel traffic congestion quick evacuation control system adopted, the problem of the congestion of the traffic of the tunnel can be solved, and a lot of time can be saved for the vehicles. The tunnel traffic congestion quick evacuation method and the tunnel traffic congestion quick evacuation control system have high implementation possibility and higher economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of traffic management, and relates to a solution to traffic jams, in particular to a control method and a control system for rapid evacuation of road and tunnel jams. Background technique [0002] With the rapid development of expressway construction in our country, the number of expressway tunnels maintains a rapid growth trend, and with the development of economy, the traffic flow in expressway tunnels continues to increase, and the phenomenon of traffic congestion is becoming more and more prominent. Since tunnels are generally one-way streets and cannot be reversed, it is also difficult to enforce traffic laws on tunnel congestion. Traffic congestion will also induce a series of problems such as traffic safety accidents, environmental pollution, increased travel time, and increased energy consumption of vehicles. Therefore, designing a fast evacuation control method and control system for tunnel traffic ...

AI Technical Summary

Problems solved by technology

Since tunnels are generally one-way streets and cannot be reversed, traffic law enforcement is also difficult for tunnel congestion.

Traffic congestion will also induce a series of problems such as traffic safety accidents, environmental pollution, increased travel time, and increased energy consumption of vehicles. Therefore, designing a fast evacuation control method and control system for tunnel traffic congestion will help alleviate tunnel traffic congestion and improve tunnel traffic safety. It is particularly important to reduce the environmental pollution of tunnels and improve the level of traffic management in tunnels.
