Intersection dynamic detouring induction control method and device in vehicle-road coordination environment, and storage medium

Abstract

The invention discloses an intersection dynamic detouring induction control method and device in a vehicle-road coordination environment, and a storage medium. The method comprises the steps: S01, obtaining real-time traffic information of an intersection to be adjusted and a controlled upstream intersection of the intersection to be adjusted; S02, calculating the queuing length of straight vehicles at the intersection to be adjusted, and if the queuing length exceeds a preset threshold value, starting detouring induction control; S03, obtaining the traffic flow state of a straight lane of the controlled upstream intersection; S04, determining the straight traffic flow needing to detour at the controlled upstream intersection, and judging the current straight lane resource of the controlled upstream intersection; S05, configuring a straight lane of the controlled upstream intersection as a detour lane, determining the detour direction of the detour lane, and updating the signal timing; and S06, updating the detouring induction indication information of the upstream of the controlled upstream intersection. According to the invention, the traffic efficiency of straight vehicles at the congested intersection can be effectively improved, the queuing time of the vehicles is reduced, and the traffic congestion condition is relieved.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic management and control, in particular to a dynamic detour induction control method, device and storage medium at intersections in a vehicle-road collaborative environment. Background technique [0002] With the rapid increase of the number of motor vehicles, the traffic congestion in the city is becoming more and more serious. Compared with intersections with low traffic, intersections with high traffic often belong to frequent congestion. For example, intersections with high traffic intersected by main roads are usually intersections with frequent congestion. And in this kind of frequently congested intersection, due to the excessive flow of straight vehicles, the queuing length will be too long, which will cause the congestion to spread. Therefore, how to alleviate the traffic congestion problem of this kind of frequently congested intersection in urban roads is very important for al...

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.
