Driving guiding early-warning system in adverse weather for preventing second traffic accident

Abstract

The invention discloses a driving guiding early-warning system in an adverse weather for preventing a second traffic accident. A microcontrol processor makes a wireless signal with a specific frequency to vehicles in a certain range and simultaneously starts a sound-and-light alarm device outside the vehicle, thereby reminding prevention of the second traffic accident, and preventing an accident damage deteriorating effect. On the adverse conditions such as rain, snow, mist, haze and sand, road visibility information or road control information is received through an automatic receiving and transmitting system, wherein the road visibility information or road control information is transmitted by a road management department or a police traffic management department through a fixed or portable early-warning information device, thereby reminding a local driver of keeping the safe vehicle distance and vehicle speed, and transmitting vehicle speed and lane information to subsequent vehicles in the same direction. The subsequent vehicles in the same direction use the information as a guidance, and the information is passed for guiding the vehicle to keep a safe vehicle distance in a safe vehicle speed, thereby realizing ordered passing and preventing accidents.

Description

technical field [0001] The invention relates to the technical field of traffic early warning, in particular to a driving guidance and early warning system for preventing secondary traffic accidents and bad weather. Background technique [0002] 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. [0003] 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 pla...

Problems solved by technology

[0003] However, at present, only placing warning signs 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 behind 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 a series of rear-end collisions and secondary accidents, expanding the consequences of accident damage

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
