Intersection scheduling method and system

Abstract

The invention discloses an intersection scheduling method and system, and the method comprises the steps: obtaining a target vehicle which needs to drive to a target intersection in a target road section and is located at other road sections, and determining the driving direction of the target vehicle at the target intersection; determining a parking area and a lane changing area of a target road section corresponding to the target vehicle in the driving direction of the target vehicle; wherein the parking area is a lane where the target vehicle passes in the target road section and does not need to change the lane, and the lane changing area is a lane where the target vehicle needs to change the lane to reach the parking area in the target road section; and performing path planning on the target vehicle according to the parking area and the lane changing area so as to schedule the target vehicle to drive into the target road section according to the optimal driving strategy and arrive at the target intersection, thereby effectively improving the intersection passing safety and passing efficiency of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle dispatching, in particular to an intersection dispatching method and system. Background technique [0002] With the increase of car ownership in domestic cities, intersections have gradually become the bottleneck of road traffic, and the efficiency and safety of vehicles at intersections need to be improved urgently. When a vehicle passes through an intersection and enters the next intersection, the vehicle will select the corresponding driving trajectory according to the driving direction after entering the intersection. The intersection process is the most complicated during the driving process of the vehicle, and the same is true for automatic driving technology. In the prior art, the most common vehicle scheduling method at intersections is traffic light scheduling. Although it can ensure safety, its scheduling efficiency is relatively low, and traffic jams usually occur. Moreover, intersectio...

Problems solved by technology

In the prior art, the most common vehicle dispatching method at intersections is traffic light dispatching. Although it can ensure safety, its dispatching efficiency is relatively low, and traffic jams usually occur. Moreover, intersections are also high-incidence areas for vehicle accidents, and the safety is low.

Coupled with the gradual popularization of automatic / assisted driving, the traditional intersection dispatching method is less intelligent and less automated, and is not suitable for automatic / assisted driving vehicles
