Design And Implementation Of Three-dimensional Simulation Of Vehicle Navigation System

The Vehicle Navigation System is the section of the Intelligent Transportation System. This system interstates with many technology such as the global position technology , the geographic information technology, the modem technology, communication technology and embedded technology . It can offer many kinds of the important services such as timely and efficiently for a driver while driving. The Vehicle Navigation System can improve the designment of the network of road. Also, Its application greatly alleviated the trouble of city transportation system.The thesis analyses the situation of the Vehicle Navigation System and makes the thorough study on the technologies and the applied developments of the three-dimensional models. Under the help of satellite, GPS could be used in the car. So, the system makes up the Global Positioning System, which can lead car to correct load in the driving. The development of the three-dimensional Global Positioning System can provide the kide of geographic information services. And it establishes an efficient shortest path algorithm while driving.According the analysis for this project, this thesis designs the three-dimensional simulation of vehicle navigation systems. This project is made up of several main modules, respectively, by the navigation module, the shortest path module, track display modules, voice modules. These modules settle the functions of the right GPS navigation function and electronic maps and two-dimensional maps and switch between three-dimensional scene and digital maps and path planning and other functions. The shortest walking between the paths can bring the low energy consumption, lower transport costs, small pollution, passenger traffic, and high efficiency.The entire system would be satified with Weifang City residents and the foreign business visitors. It can provide the city information, site information, such as the shortest route to the information content and the provision of urban traffic conditions, the spatial distribution of urban road and so on. The three-dimensional Global Positioning System can provid the public convenient and friendly trip which can be start from inquiry, in order to drive users to make travel decision-making aids.
