Low Road visibility is the main meteorological disaster that affects traffic.
Road visibility has a direct impact on traffic safety, especially on highway traffic safety.
The low road visibility weather often causes the congestion and sealing of the highway, which leads to the interruption of traffic and transportation.
Due to the influence of the dense fog, there are even dozens of heavy traffic accidents that collide with hundreds of cars on the expressway, causing huge economic losses and casualties, causing great loss to the people’s life, property, local economy and the economic benefits of the highway itself.
Due to the networking of highways, the closure of some highways often leads to traffic jams and even traffic failures on other roads or small towns.
In addition, serious traffic accidents caused by low road visibility are more shocking.
According to statistics, traffic accidents caused by the influence of heavy fog on the expressway account for about 1/4 of the total number of accidents, and the accident rate of freeway in fog is 10 times as high as usual.
