Description
Technical Field
The invention belongs to the technical field of intelligent traffic, and particularly relates to a crossing collision early warning system and a control method thereof.
Background
The international medical journal "lancet" public health journal discloses a report about the death rate of Chinese traffic accidents according to data acquired from national disease monitoring points. From 2006 to 2016, an average of over 1 million people die of traffic accidents each year, as the number of deaths from traffic accidents is as high as 115255. The data reported by the lancets, from 2006 to 2016, is 2-3 times the mortality rate of rural traffic accidents, all the time in cities. The public security department road traffic safety research center counts that the accident number accounts for 84% in 2017-2019 in the country, the plain and mountain areas in rural areas, wherein the accident number of the road sections in the plain area is 3.4 times of the accident number of the intersections. The traffic accident mortality rate in rural areas is so many times higher than in cities for several reasons: first, motor vehicle drivers and passersby in rural areas are easy to relax and vigilant. Secondly, the construction of the basic traffic facilities in rural areas is poorer than that in cities. Thirdly, traffic regulations in rural areas almost do not exist. Fourthly, the medical treatment level is lower in rural areas than in cities. Therefore, the traffic accident can be effectively reduced by alarming the passing vehicles and pedestrians at the road junction of the country.
