Background technique

With the increase of traffic flow, traffic accidents frequently occur due to weather, road conditions or improper driving. Now the general requirement is that when a traffic accident occurs, it should be 50 meters behind the accident vehicle on the urban road, at night and in rain and fog. Accident warning signs should be placed within 100 meters per day, at least 100 meters during the day on expressways, and 200 meters away at night and in rainy and foggy days to reduce accident damage, rescue personnel in time, and reduce the risk of secondary accidents.

But at present, only taking warning signs to place is far from being able to solve the occurrence of secondary accidents. The placement of warning signs often cannot be placed according to the required distance, causing other vehicles in the back to have insufficient reaction braking time, resulting in secondary accidents. Or even if the warning signs are placed according to the requirements, but because some vehicles are too fast, the traffic volume is large, and the size of the accident is different, there is not enough distance and enough capacity to place them, which will affect the warning and prevention effect. Especially on the highway, it is very easy to cause the occurrence of serial rear-end collision secondary accidents, and expand the accident damage consequences. Or simply closing the expressway due to the deterioration of traffic conditions caused by ice, snow or smog will cause time lag to the logistics industry, drivers and passengers will have to sit and wait, the loss of tolls from the road management department, and the sudden increase in the safety responsibility pressure of the traffic safety department, etc. , but also increased the risk of driving travel.

Therefore, it is necessary to design a new traffic guidance and early warning system for preventing secondary traffic accidents and bad weather, and to solve the above-mentioned potential safety hazards by technical means.
