摘要：随着私人汽车在中国的普及，车载导航仪成为了日常生活中必不可少的工具。车载导航系统的路径规划的研究无论是从方便驾驶员出行，提高运输效率，优化城市交通，还是在改造与提升交通管理系统上，都对现代的交通道路起着十分重要的影响，因此受到社会和政府部门的关注和大力支持。

本论文介绍了车载导航系统的发展历史和国内外研究现状，以及GPS车载导航系统的组成、功能、实现过程、路径规划算法以及地理信息系统的功能。并以MaoInfo为工具，在路径规划系统中实现了地图的基本操作。本文重点研究了车载导航系统的路径规划问题。综合考虑并比较了多种最短路径的选择算法,并对其优缺点进行了分析。

ABSTRACT

With thepopularization of private cars in China，the navigatorsbecame the daily life of the necessary tools. The car's navigation system pathplanning research whether from convenient drivers travel to improve transportefficiency and optimize the urban traffic, or in the reform and improve trafficmanagement system, all the way to modern traffic plays a very importantinfluence, and it is by society and government departments of the attention andsupport.

This paperintroduces the development history of the car's navigation system and researchstatus from domestic and structure, function and the realizationof the whole system are demonstrated in detail in this thesis. TheGIS(Geographic Information System) theory is introduced .By using MapInfosoftware as a supporting platform, basic operation of map are realized. Thealgorithms of Route Planning are discussed in detail. Think over and comparemany shortest path algorithms and present a improved algorithm based on theoriginal Dijkstra algorithm in this thesis. It saves memory space and increasesefficiency.

Keywords:  GPS  GIS  Vehiclenavigation System  Route-Planning  Dijkstra algorithm
