Warning of Potential Collision for Vehicles

A moving vehicle may very likely run into accidents. The occurrence rate of accidents would be largely reduced if the driver were warned in advance, even only 0.5 s earlier. For a running vehicle, the driving route within short time before collision has the character of Markov. In this case, we only have to consider the coordinates of position within a short range, rather than the running status during the past long period. Within short period before collision, the driving route can be basically divided into two states: a straight line and a binomial curve. In this paper, we propose a mechanism for sending collision warning messages to running vehicles.
