Intelligent Vehicle Navigation Electronic Map Integrated Applied Research

The modernization of the traffic is the world's countries to achieve the modernization of the state an important element. However, countries in the process of modernization of traffic encountered in the vehicle to highlight the contradiction between the growth rate much higher than the roads and other transport facilities growth.In this form, there is simply recognize that road infrastructure can not fundamentally solve the traffic problems, and thus seek to use other methods to improve the efficiency of existing roads, such as improved traffic control signal, an increase lane or change lanes in accordance with the directions of traffic flow, and optimize traffic routes. With modern computer, information, communication technology and space development of information technology means there is a high-tech solutions - automotive electronic navigation system.Geo-spatial information is automotive electronics navigation system an important support platform, is the integration of a variety of socio-economic information and traffic information on the positioning of the framework. Navigation electronic map of the navigation system's data base, is a GPS vehicle navigation system soul. It is in accordance with the specific data model will be based on geographic information, road traffic information, POI information, information such as automated guided the organic integration of multi-source information together, through the navigation software to show to the drivers. Users of navigation products satisfaction depends largely on navigation electronic map in the information rich and the accuracy rate, so high-end navigation electronic map products contain a large number of POI information and guidance information to help drivers easily find the destination, and in the road the process to give an intuitive, accurate advice.Intelligent vehicle navigation system combines vehicle, transportation, geographic information systems, communications, system science and other fields related to technology, has become an important tool for traffic navigation. This article systematically expounded in-car navigation system positioning technology, dynamic path planning methods, navigation electronic map data dynamic maintenance and updates, traffic information collection, processing and publishing, the road traffic conditions forecast the key technology and its development at home and abroad the status quo, pointing out the various technical deficiencies in the existing number. Intelligent vehicle navigation technology and integrated application of the electronic map is a comprehensive study of high-tech applications, and its enormous economic and social significance. In this paper, closely follow the market demand, a unified technical models, seize the space vehicle navigation positioning technology services market this new profit growth point. Application of the results of the project will be beneficial to our province the rapid development of car navigation industry, has a huge market value and social value.
