Intelligent Transportation System development and application of mitigation and improvement of urban traffic conditions, and promote traffic safety and improve the efficiency of road access is important. Vehicle navigation system is the Intelligent Transportation Systems (ITS) in an important component of the mobile terminal by car, wireless communications and vehicle monitoring center link is composed of three parts. 3S technology (GPS, GIS and RS) is the application of car navigation system to achieve an important foundation.  In this paper, the intelligent traffic systems and vehicle navigation system research and development at home and abroad, the status quo, briefly expounded on GPS and GIS work. GPS receiver by analyzing the data format to study the GPS data collection and processing. Paper-board electronic maps of the design and production process of simple e-map features, such as electronic maps to enlarge and narrow, roaming, distance and area measurement method, etc.. Papers focus on map-matching algorithm of the basic principles of the shortest path search algorithm, the basic method, in VC + + environment, on the Dijkstra algorithm programming. Keywords: Intelli
