Study on Vehicle Navigation System with Real-Time Traffic Information

The traditional vehicle navigation system is an isolated system, which can not meet the demanding of public traveling and traffic manage. Real-time traffic information is one of the most important applications for the driver and an essential feature of vehicle navigation system. Now today, most of the former navigation systems are developed based on static data instead of real-time or dynamic traffic information. In this paper, it gives the framework of vehicle navigation system based real-time traffic information, discusses spatial and temporal characteristic of real time navigation data and gets the real-time navigation data model in GIS-T, and successfully deploys it, which receives traffic information from the terrestrial digital multimedia broadcasting (T- DMB) system.
