Description

technical field

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

[0002] Fog is the natural enemy of expressway operation safety, and it is also a state that is often accompanied by traffic accidents with heavy casualties, especially at night, it is not easy to be discovered by drivers. The timing, location, and size of fog blobs tend to be random, and the blobs move around. For highways at night, 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. There have been many serious traffic accidents d...
