Wrong-direction running warning and risk avoiding method based on vehicle and road cooperation technology

Abstract

The invention discloses a wrong-direction running warning and risk avoiding method based on the vehicle and road cooperation technology, and the method comprises the following steps: S1, broadcasting the movement state information of all vehicles; S2, obtaining the information of vehicles in a communication range through a road side unit; S3, determining a road R, a lane L and a running direction D of each vehicle; S4, matching a passing direction Dm of the corresponding lane through the road R and lane L of each vehicle; S5, judging whether an angle between the running direction D of each vehicle and the passing direction Dm of the corresponding lane is greater than a preset angle or not: executing step S6 if the angle is greater than the preset angle, or else, executing step S2; S6, determining a vehicle running in a wrong direction; S8, judging whether ttr of a turn-round scheme is greater than trm of a wrong-direction running scheme or not: continuing the running in the wrong direction if the ttr of the turn-round scheme is greater than the trm of the wrong-direction running scheme, or else, turning round. The beneficial effects of the invention are that the method reduces the collision risks, caused by that a vehicle enters into a wrong lane, through the vehicle and road cooperation technology, and recovers the safe passing state of a road as quickly as possible, thereby improving the passing safety level and efficiency of the road.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a method for warning against traffic and avoiding risks based on vehicle-road coordination technology. Background technique [0002] The Internet of Vehicles is through the Internet technology, all vehicles can transmit various information of themselves to the central processing unit. Through computer technology, the information of these large numbers of vehicles can be analyzed and processed to calculate the best routes for different vehicles, issue reports on road conditions and adjust signal light cycles. [0003] The vehicle-to-road collaboration technology V2X of the Internet of Vehicles includes the interconnection of vehicles and vehicles (V2V), vehicles and roads (V2I, Vehicle to Infrastructure), vehicles and people (V2P), vehicles and centers (V2C), etc. Communication and roaming between heterogeneous networks, guaranteeing real-time, serviceability and network ubiqu...

Problems solved by technology

[0006] In order to solve the existing methods of preventing vehicles from going against the road, there is no effective means to assist the driver to obtain the relevant information of the road where the driving route is located to judge whether he is in the retrograde or whether there is a retrograde vehicle threatening his own safety and how to avoid the risks caused by the retrograde , so as to give the driver sufficient reaction time to avoid risks and prevent accidents. The present invention proposes a method for retrograde warning and risk avoidance based on vehicle-road coordination technology
