A vehicle route planning method and system for vehicle-road coordination

Abstract

The invention discloses a vehicle path planning method and system for vehicle-road coordination, and specifically relates to the field of traffic control, including: taking one of the sub-areas in a designated area as a target area; taking the position in the target area as a target area; Vehicles at the navigation destination are classified into target groups, and the target group includes several internal vehicles located in the target area and several external vehicles located outside the target area; For any one of the internal vehicles, the path planning is performed based on the time spent; for any one of the several external vehicles, the path planning is performed based on the spatial distribution balance. The vehicle route planning method is used to plan the navigation route of the vehicle whose navigation destination is in the target area and the vehicle is located outside the target area, which can reduce the probability of new congestion of the vehicle outside the target area and ensure smooth traffic of the vehicle.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a vehicle path planning method and system for vehicle-road coordination. Background technique [0002] Vehicle-road coordination is a road traffic system that implements vehicle-vehicle and vehicle-road dynamic real-time information interaction in an all-round way. Vehicle-road coordination carries out vehicle active safety control and road collaborative management on the basis of full-time and spatial dynamic traffic information collection and integration, fully realizing Effective collaboration between people, vehicles, and roads ensures traffic safety and improves traffic efficiency. [0003] Car navigation route control is one of the basic contents of vehicle-road coordination. Statistics show that in the urban environment, the flow of people (vehicles) at different times has obvious differences. causing congestion in the area. [0004] The current navigation system will only...

AI Technical Summary

Problems solved by technology

[0004] The current navigation system will only plan the navigation route based on the current traffic conditions, based on simple parameters such as the shortest distance and the shortest time spent; Accumulation occurs in the middle, thus forming new congestion, which is not conducive to vehicle traffic
