Description

Technical Field

[0001] The invention relates to a road danger warning technology. Background Art

[0002] The types of dangerous situations on highways include traffic collisions, vehicle failures, weather effects, foreign object interference, etc. Since the intensity of highway dangers is high and affects life safety, the dangers on highways are a high-intensity danger. Collision accidents not only affect the vehicles involved, but may also cause chain accidents, causing traffic congestion and safety hazards on a larger scale. In addition, the handling of collision accidents and subsequent rescue will also take up a lot of resources, which will have a serious impact on the traffic efficiency of highways. Vehicle failures may cause vehicles to stop suddenly or lose control, which will lead to traffic accidents. For example, tire blowouts, engine failures, or brake failures may cause vehicles to lose control in a short period of time, posing a serious threat to driving safety. Bad weather such as rain, snow, and fog will make the road slippery, making it difficult for drivers to control the direction, thereby increasing the risk of traffic accidents. There are often foreign objects such as scattered objects and dropped objects on highways, such as screws and tire fragments. These foreign objects may interfere with the driving of vehicles, such as puncturing tires and damaging chassis, which will lead to traffic accidents. The types of dangerous situations on highways are diverse and complex, which have a significant impact on driving safety and road smoothness. Summary of the invention
