Problems solved by technology

[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 is extremely low. For emergency traffic accidents, there is basically no time to take into account the traffic of upstream vehicles. If the accident processing time is a little longer, congestion will quickly spread upstream. Not only that, due to the lack of accident site management, chaotic traffic conditions may even induce Secondary accident resulting in secondary injury

Embodiment 1

[0032] see Figures 1 to 4 , when the accident area is located in the left two lanes of a four-lane expressway, a traffic signal control method suitable for expressway accident handling, based on a portable traffic signal control system, the system includes signal light modules, LED screens, camera, voice module, controller, power supply module and retractable device, the portable traffic signal control system can be erected separately or fixedly installed on the top of the motor vehicle, the method includes the following steps:

[0033] S01. Determine the position of the control system, set the control system in the middle of the two left lanes in the upstream direction of the accident area, and use the telescopic device to raise the signal light module, LED screen, camera, and voice module to the height visible to vehicles in the upstream direction.

[0034] S02. Set a temporary stop line, set a temporary stop line upstream of the control system, the distance from the contro...

Embodiment 2

[0045] see Figure 5-8 , when the accident area is located in the center of a three-lane expressway and two lanes on the right, another embodiment of a traffic signal control method can also be drawn based on a portable traffic signal control system, comprising the following steps:

[0046] S01. Determine the position of the control system, set the control system in the middle of the accident area in the middle of the upstream direction and the middle of the right lane, and use the telescopic device to raise the signal light module, LED screen, camera, and voice module to the upstream direction of the lane vehicle visibility height;

[0047] S02, setting a temporary parking line, setting a temporary parking line in the upstream direction of the control system, the distance from the control system to the temporary parking line meets the space requirements for the vehicle to switch to a passable lane;

[0048] S03, input road condition parameters, display content and broadcast ...

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...
