System and method for preventing secondary accident of vehicle in highway tunnel

Abstract

The invention provides a system and a method for preventing a secondary accident of a vehicle in a highway tunnel. The system comprises an accident detecting device, a vehicle detecting device, a reminding device, an active intervention device and a central processor. The accident detecting device is arranged in the tunnel and is used for detecting whether an accident occurs in the tunnel. The active intervention device is arranged in front of the inlet of the tunnel. The vehicle detecting device is arranged in front of the active intervention device and is used for determining whether a vehicle is going to drive into the tunnel. The central processor, the accident detecting device, the vehicle detecting device, the reminding device and the active intervention device perform mutual communication. When the accident occurs in the tunnel and the vehicle is going to drive into the tunnel, the central processor make the active intervention device and the reminding device operate. When an accident occurs in the tunnel, the active intervention device performs compulsory speed reduction on the vehicle which is going to drive into the tunnel, thereby facilitating reminding information acquisition by the driver and effectively reducing the secondary accident in the tunnel.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a secondary accident prevention system and method for vehicles in an expressway tunnel. Background technique [0002] In modern society, in order to improve the efficiency of vehicle circulation and save time, tunnels are often excavated in the mountains, and vehicles pass through the tunnels, which provides great convenience for people. Tunnels are generally dug into two lanes. Compared with the number of road lanes outside the tunnel, the traffic flow inside the tunnel is relatively large, and the lighting inside the tunnel is quite different from that outside the tunnel. The probability of traffic accidents such as collisions and scratches is higher. Due to the particularity of the tunnel, the efficiency of accident rescue in the tunnel is low. Once an accident occurs in the tunnel, the casualties and losses are even more severe. At the same time, since the outside vehic...

Problems solved by technology

Due to the particularity of the tunnel, the rescue efficiency of accidents in the tunnel is low. Once an accident occurs in the tunnel, the casualties and losses will be even greater

At the same time, because external vehicles often cannot know the tunnel road condition information at the first time, it is easy to make the car behind hit the accident vehicle and cause a secondary accident, which brings greater economic losses to people.

In the prior art, by setting a display screen or a voice prompter at the tunnel entrance, passing vehicles are notified of the road conditions in the tunnel, but this prompt is not targeted, and because the speed of the vehicle is too fast on the expressway, the driver often does not have enough The time to capture the prompt message
