Design Of Expressway Early Safety Warning System Based On IoV

With the economic development of China,the number of household cars belonging to citizens has increased geometrically,according to the Ministry of Public Security Traffic Management Bureau,by the end of 2015,the number of China's vehicles reached 279 million and the registered drivers exceeded 320 million.At the same time,the construction of highway has stepped faraway.By the end of 2015,the total mileage of China's highways has reached 123,000 km.Expected to the end of 2020,this number will reach 168,000 km.However,the construction of China's highways still have plenty of limitations,for example,backward facilities,low-intelligent management,leading to traffic congestion,frequent traffic accidents and other traffic problems.In that way,it's significant and meaningful to use the wireless communications technology,automotive Internet technology and intelligent management theory to design a systematic and reliable highway security warning system,which will help to improve the use efficiency and comfort of highway and to reduce the incidence of traffic accidents.In this paper,based on the development status of China's highway and current technology level of China's car network,we build the early-security warning system of highway.
