Lane-level navigation system and lane-level navigation method thereof

Abstract

The invention relates to a navigation system and in particular relates to a lane-level navigation system. The lane-level navigation system comprises a server and a vehicle-mounted navigation terminal; the server is in communication connection with the vehicle-mounted navigation terminal; the vehicle-mounted navigation terminal comprises a controller, a communication module and a positioning device; the positioning device is a high-precision positioning device and capable of positioning a vehicle on a lane; the server obtains a lot of relatively accurate real-time positions of the vehicle on the road and positions the vehicle on the lane; the server is capable of calculating the jam index of the lane and the average running speed of the lane, and predicting the jam index of the lane and the average running speed of the lane in a future period of time; a running route can be selected according to the jam index of the lane, the average running speed of the lane, the predicted jam index of the lane and the predicted average running speed of the lane in the future period of time; the lane-level navigation system is capable of achieving a better effect in traffic navigation.

Description

technical field [0001] The invention relates to traffic management, in particular to a lane-level navigation system. Background technique [0002] To reflect the traffic capacity of lanes or roads, road congestion index and average driving speed can be used. Road congestion index and average driving speed are important basis for traffic design, traffic management, and traffic navigation; especially real-time road congestion index and average driving speed can be used for real-time traffic management and traffic navigation; congestion accurate to lane level Index and average driving speed are important basis for traffic design, traffic management, and traffic navigation; real-time congestion index and average driving speed accurate to the lane level are of great significance to real-time traffic dispatching and traffic navigation. [0003] The existing Chinese patent 00816053.8 proposes a method and system for a real-time distributed navigation system; it generates a high-pr...

Problems solved by technology

[0007] The existing Chinese patent 201210507080.0 proposes a method for judging urban road traffic status based on section detectors; a comprehensive congestion evaluation index, i.e. traffic congestion index, is constructed using three traffic flow parameters: traffic flow, speed, and time occupancy rate. The traffic congestion index judges the traffic status of the road section; however, this invention is based on the traffic information of a certain detection section on the road section, and the information collection is less, and the data accuracy is lower
