Abstract

The invention provides a traffic signal control method suitable for highway accident handling, which is based on a portable traffic signal control system, and the control system comprises a signal lamp module, an LED screen, a camera, a voice module, a controller and a telescopic device. The traffic signal control method comprises the following steps of: determining a position of the control system; setting a temporary stop line; inputting road condition parameters, display content and broadcast content into the controller; and enabling the controller to process the road condition parameters to obtain a phase sequence instruction, sending the phase sequence instruction, the display content and the broadcast content to the signal lamp module, the LED screen and the voice module respectively, and starting the camera to record field data by means of the controller. According to the traffic signal control method provided by the invention, the current situation that no traffic control exists in the accident scene at present is changed, and the traffic dispersion efficiency of the highway accident scene is improved.

Description

technical field

[0001] The invention relates to the technical field of traffic control, in particular to a traffic signal control method suitable for expressway accident handling. Background technique

[0002] The expressway system is a closed system. Once an accident occurs, it will inevitably have a huge impact on the upstream traffic flow. Serious traffic accidents may even lead to a long queue of upstream vehicles stretching for dozens of kilometers, which seriously affects the normal operation of the expressway system. With the continuous increase of highway traffic volume, the number of accidents also increases, and the traffic congestion caused by accidents also continues to increase.

[0003] The current traffic management in the accident area of ​​the expressway is basically realized by the vehicles bypassing the accident area by themselves. Due to the lack of corresponding rules and control measures, the vehicles interact with each other, and the traffic efficiency...
