Traffic guidance method, device, system and storage medium based on vehicle-road coordination

Abstract

The embodiment of the invention discloses a vehicle infrastructure integration-based traffic guidance method, equipment and system and a storage medium. The method comprises the steps of firstly, acquiring vehicle information on a lane changing region in real time by intelligent terminal sensing of road-side equipment or vehicle road communication sensing, wherein the vehicle information comprisespositions, speeds and directions of at least two vehicles; secondly, determining a lane changing induction scheme with shortest forecast passing time of each target vehicle according to the vehicle information, wherein the lane changing induction scheme is hypothesized in a way that a corresponding target vehicle changes a lane from a road segment within a designated range, wherein the target vehicle is at least one of the two vehicles; and finally, prompting the target vehicle to change the lane from the road segment within a recommended and designated range from the corresponding lane changing induction scheme. If the scheme is employed, the lane changing can be completed with relatively short time, traffic congestion is released, the situation that the congestion is increased due to concentrated lane changing at an inappropriate road segment, and the integral traffic condition of a larger region range is further improved.

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 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 vigorously promoted and widely used. 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.

Problems solved by technology

[0004] However, this traffic guidance method does not take any guidance measures in the exit area where traffic congestion has already occurred, nor can it improve the current congestion level of the exit area and shorten the passage of vehicles already in the exit area to change lanes and enter the exit ramp. time
