Traffic guidance methods, equipment, systems and storage media based on vehicle and road collaboration

Abstract

An embodiment of the invention discloses a traffic guidance method, traffic guidance equipment and a traffic guidance system based on vehicle-road cooperation, and a computer storage medium. The provided traffic guidance method based on vehicle-road cooperation comprises the steps of: acquiring driving state information of ramp vehicles and main road vehicles in a confluence region, wherein the driving state information comprises vehicle center positions, vehicle speeds and vehicle lengths; predicting whether a target vehicle collides with the main road vehicles or not in the process of driving from a ramp into a main road based on the driving state information, wherein the target vehicle is one of the ramp vehicles; generating lane changing prompt information according to a prediction result, generating lane changing early warning information if the prediction result shows that the target vehicle collides with the main road vehicles, and generating a lane changing appropriate information if the prediction result shows that the target vehicle does not collide with the main road vehicles; and prompting the lane change prompting information to the target vehicle.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a traffic guidance method, equipment, system and computer storage medium based on vehicle-road coordination. Background technique [0002] With the continuous development of electronic equipment, communication technology and the new generation of Internet and other technologies, intelligent transportation, especially the vehicle-road coordination system, has been promoted and applied. The vehicle-road coordination system can realize dynamic real-time information interaction between vehicles and vehicles, and carry out vehicle active safety control and road collaborative management on the basis of full-time and spatial dynamic traffic information collection and fusion, which is helpful for realizing effective coordination of people, vehicles and roads and ensuring traffic Safety and improving traffic efficiency are of great significance. [0003] On the...

Problems solved by technology

The choice of this timing is a labor-intensive thing for the driver. If the choice is not good, the following accidents are likely to occur: 1) Only pay attention to keeping the distance between the car in front and ignore the car behind, resulting in a rear-end collision accident; 2) ) Only pay attention to the distance between the vehicle behind and you to change lanes, ignoring the position of the vehicle in front, causing a rear-end collision with the vehicle in front; 3) Having reached the end of the ramp but not completing the lane change, changing lanes in a hurry, resulting in a collision with vehicles on the main road; 4) There is a blind spot in the rearview mirror of the vehicle, and the vehicle behind cannot be seen, so that the vehicle collides with the vehicle behind when changing lanes
