In-vehicle navigation system based on dynamic traffic information

摘要

This paper proposed a spider-web punctual road network model and a dynamic traffic information model suitable for use in the in-vehicle navigation system. Based on these models, the dynamic traffic information can integrate with the embedded GIS efficiently. The in-vehicle navigation system designed in this paper can realize the display and query of dynamic traffic information in real-time, and the optimal dynamic routing according to dynamic traffic information can avoid traffic jams automatically. The application experiments showed the feasibility and effectiveness of the road network model and the dynamic traffic information model.
