Technical field

The present application relates to an early warning system for preventing serial collision on a highway, and belongs to the technical field of traffic control systems.

Background technique

At present, the national highway mileage has reached 131,000 kilometers, the number of motor vehicles is 285 million, and the number of motorists is 296 million. The number of deaths and economic losses caused by highway accidents caused by weather, road conditions, car conditions, and driver's professional level and fatigue factors are alarming. Most of the major accidents were caused by serial crashes. "Overview of the serious traffic accidents that have occurred in the country in recent years, due to the death toll of more than 10 to 30 people, their tragic accident scenes and huge loss of life and property. In the society, it has caused strong repercussions, and it has also attracted the attention of people of insight from all walks of life. Taking 2005 as an example, there were 450,254 road traffic accidents in the country, 98,738 people died, 469,911 people were injured, and direct property losses were 1.88 billion yuan. Among them, 47 heavy traffic accidents, 807 deaths and 705 injuries. One death was 10 to 19 people, 34 deaths, 446 deaths, 531 injuries; 20 to 29 people, 11 deaths, 275 deaths, 134 injuries; 30 There are 2 people, more than 86 people, and 40 people injured." The frequent occurrence of road traffic accidents is a side effect brought about by the rapid development of the economy and society. In a sense, it is not transferred by human will.
