Dynamic detour guidance control method, device and storage medium for intersection under vehicle-road coordination environment

Abstract

The present invention discloses a dynamic detour induction control method, device and storage medium at an intersection under a vehicle-road collaborative environment. The steps of the method include: S01. Obtain real-time traffic information of the intersection to be adjusted and the controlled upstream intersection of the intersection to be adjusted; S02 .Calculate the queuing length of straight-going vehicles at the intersection to be adjusted, and start detour induction control if it exceeds the preset threshold; S03. Obtain the traffic flow status of the through lane at the controlled upstream intersection; S04. Determine the need to detour at the controlled upstream intersection The flow of through traffic, and judging the current through lane resources at the accused upstream intersection; S05. Configure a through lane at the accused upstream intersection as a detour lane, determine the detour direction of the detour lane, and update the signal timing; S06 .Update the detour guidance information upstream of the accused upstream intersection. The invention can effectively improve the passing efficiency of straight vehicles at congested intersections, reduce the queuing time of vehicles, and alleviate traffic congestion.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic management and control, in particular to a method, a device and a storage medium for dynamic detour induction control at an intersection under a vehicle-road coordination environment. Background technique [0002] With the rapid growth of the number of motor vehicles, the traffic congestion in cities is becoming more and more serious. Compared with intersections with small traffic, intersections with large traffic are often congested. For example, intersections with large traffic that intersect with main roads are usually congested intersections. At such frequently congested intersections, the queue length is too long due to the excessive flow of straight vehicles, which will lead to the spread of congestion. Therefore, how to alleviate the traffic congestion at such frequently congested intersections on urban roads is important for alleviating the overall road conditions. Traffic jam...

Problems solved by technology

This kind of method is not only complicated to implement, but also needs to rely on complex control methods, the implementation cost is very high, and it is still inevitable to be prone to congestion at intersections with large traffic volumes

[0007] To sum up, in the prior art, the method based on vehicle-road coordination is only to simply give out congestion warning information or simply adjust the signal timing at the intersection, which is actually only applicable to the case of small traffic flow, and cannot fundamentally alleviate the problem.
