Vehicle collision risk algorithm and accident pre-warning method

Abstract

The invention discloses a vehicle collision risk algorithm and accident pre-warning method, which comprise an on-board unit (OBU), a road side unit (RSU), a traffic information center (TIC) and an information communication unit (ICU). The OBU is used for acquiring vehicle speed, accelerated speed, a steering wheel angle and other parameters, and combining with a road traffic system to acquire a track angle of a vehicle and a real-time distance between two vehicles; the OBU transmits the parameters to the belonged RSU through a DSRC (Dedicated Short Range Communication) technology; the RSU transmits the vehicle parameters in an area to the TIC for risk calculation through an optical fiber / 5G technology; the result is forwarded to the OBU for pre-warning through the RSU. According to the vehicle collision risk algorithm and accident pre-warning method, traffic accidents can be prevented and controlled accurately, and thus the traffic jam and the frequent accidents can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of road traffic safety, and relates to a vehicle collision risk algorithm and an accident early warning method. Background technique [0002] With the improvement of our country's infrastructure, a national transportation network extending in all directions is basically formed, but it is an obvious fact that the complexity and congestion of the road transportation system are increasing day by day, especially the growth rate of vehicles has far exceeded that of roads and other vehicles. With the growth rate of transportation facilities, problems such as traffic congestion and frequent accidents are becoming more and more serious. [0003] With the improvement of traffic safety management level and the development of vehicle active safety technology, the traffic safety environment has been greatly improved, especially the traffic environment of expressways. According to statistics, since 2003, the number of traffic acci...
