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

Abstract

The invention discloses a driving guidance and early warning system for preventing secondary traffic accidents and bad weather. The micro-control processor controls the wireless signal of a specific frequency to transmit to vehicles within a certain range and synchronously starts the vehicle's external voice and light warning device. Please pay attention Avoid secondary traffic accidents and avoid aggravating the consequences of accident damage; under severe weather conditions such as rain, snow, haze, sand and dust, the automatic receiving and transmitting system will receive the fixed or portable early warning information device from the road management department and the public security traffic management department. The sent road visibility information or road control information reminds the driver and passengers of the vehicle to maintain a safe distance from the vehicle, and transmits the speed and lane information of the vehicle to the subsequent vehicles in the same direction. Guide vehicles to maintain a safe distance between vehicles at a safe speed, pass in an orderly manner, and avoid 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 t
