Description

technical field

[0001] The invention belongs to the technical field of traffic safety, and in particular relates to a device and a method for real-time reminder of foggy road sections by using an electronic map. Background technique

[0002] Fog is the natural enemy of highway operation safety, and it is also a state that is often accompanied by traffic accidents with heavy casualties. The timing, location, and size of fog blobs tend to be random, and the blobs move around. For expressways, traffic conditions between sections of foggy roads are good, and vehicle speeds are usually high. When the vehicle suddenly enters the foggy road section, the visibility suddenly drops from several thousand meters to less than 200 meters, even tens of meters, and what is even worse may reach less than ten meters, which is fatal to the running of the vehicle. Many serious traffic accidents have occurred in our country because of the fog, which has caused serious social consequences. [...
