Double-lane vehicle lane changing guiding method under vehicle-road cooperation

Abstract

The invention discloses a double-lane vehicle lane changing guiding method under vehicle-road cooperation, and the method comprises the steps: describing the state information of a vehicle based on acellular automaton model, carrying out the real-time effective evaluation of the threat to the vehicle in real time according to the information of surrounding vehicles, carrying out the traversal ofthe elements of a threat evaluation function, obtaining the position of a minimum value, and giving the vehicle lane changing guidance; in a double-lane environment, subjecting the observation vehicleto vehicle speed induction according to the movement trend of the forward vehicle after lane changing, so that the vehicle speed of the observation vehicle is associated with the acceleration trend of the forward vehicle after lane changing; referring to the motion trend of the backward vehicle, observing that the vehicle adopts a leading acceleration motion rule, and avoiding rear-end collisionaccidents while ensuring motion synchronization; providing early-stage speed guidance for the vehicle close to the blocking point, and avoiding the phenomenon of vehicle starting and stopping; and finally, giving a double-lane vehicle lane changing rule under vehicle-road cooperation to complete lane changing. According to the invention, the problems of vehicle congestion and road section congestion point increase in the future traffic environment are solved.

Description

technical field [0001] The invention belongs to the technical field of transportation systems, and in particular relates to a lane-changing guidance method for two-lane vehicles under vehicle-road coordination. Background technique [0002] Intelligent transportation system is the frontier field of transportation in the world at present. This field is based on the development of today's 5G era, and it is one of the key points that countries around the world are trying to inject resources into. As an important research direction of intelligent transportation system in recent years, vehicle-road coordination system is a favorable technical means to deal with traffic problems such as traffic safety, road emergencies, objective factors affecting road traffic and road traffic efficiency. Equipment, intelligent road section equipment, 5G interconnection technology, 5G communication platform, etc. will interact with vehicle status information and road conditions, and information wi...
