Embodiment Construction
[0034] The structure principle of the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0035] like figure 1 As shown, a vehicle collision risk algorithm and an accident early warning system include: an on-board unit OBU, a roadside unit RSU, a traffic information center TIC, and an information communication unit ICU. The on-board unit OBU is composed of a storage module, a DSRC communication module, and an early warning module, and is mainly used to acquire and store the motion parameters of the self-vehicle and give an early warning of the accident risk of the self-vehicle; the RSU is composed of a storage module and DSRC, 5G / It is composed of optical fiber communication modules, mainly for the transmission of vehicle parameters in the area and the push of accident risk warning information; the TIC is composed of a storage module, an information processing module and a 5G / optical fiber communicati...

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 my country's infrastructure, a national transportation network extending in all directions has basically been formed, but it is an obvious fact that the complexity and congestion of the road transportation system are increasing day by day, especially the speed of vehicle growth has far exceeded that of roads and other The growth rate of transportation facilities, traffic jams 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 highway traffic environment. According to statistics, since 2003, the number of highway traffic accidents in the country has graduall...
