Abstract

The invention discloses a method and system for guiding vehicles at an intersection based on a multi-path scheme in a vehicle-road collaborative environment. An intelligent roadside subsystem is installed at the entrance of the intersection, which can be used for real-time monitoring of vehicles entering the range of the intersection. and signal light status; the intelligent vehicle subsystem obtains the vehicle driving status data and the vehicle multi-path guidance scheme, and the intelligent traffic management system calculates the turn that the vehicle can pass through the stop line the fastest according to the intersection-related information and the predetermined multi-path guidance scheme; The intelligent vehicle subsystem recommends the optimal route to the driver according to the management system instructions. The guidance system is suitable for vehicle guidance using a multi-path guidance scheme, which can effectively reduce the waiting delay of vehicles at intersections, reduce the time of vehicles staying at intersections, achieve the purpose of alleviating traffic congestion and reducing the overall travel time of the road network.

Description

technical field [0001] The invention relates to the technical field of vehicle path guidance, in particular to a vehicle guidance method and system at an intersection based on a multi-path scheme in a vehicle-road collaborative environment. Background technique [0002] Vehicle guidance system is an important part of intelligent transportation system. On the one hand, the vehicle guidance system can assist the driver in making route decisions and improve travel efficiency; on the other hand, by guiding the driver's driving route reasonably, it can change the operating state of the road network and realize the reasonable distribution of traffic flow in the road network. Alleviate urban traffic congestion. The traditional navigation system mainly calculates the shortest path through the static shortest path algorithm. However, since real-time changing road conditions (such as congestion, traffic accidents, etc.) are not considered, the shortest path obtained may not be the p...
