摘要
在车辆导航系统中,采用GIS技术可以更直观地掌握交通、车辆和路径等动态信息。在分析路径规划系统组成和工作原理基础上,着重讨论了道路网的拓扑结构和数据组织形式、空间信息和属性信息的关联以及路径规划的算法实现,采用VC++、MapX控件和数据库技术实现了路径规划系统。实验证明,利用MapX组件可以高效地建立路径规划系统,系统的数据结构和路径规划算法能较好的满足起点终点的选择、查询和快速路径搜索等系统要求。
Using GIS technology is intuitionistic to obtain the dynamic information of transportation, vehicles and routes in intelligent vehicle navigation system. The development of the route guidance information system is introduced using VC＋＋, MapX component and database technology. Topologic structure and data structure of traffic networks, association between spatial data and attribute infor- mation, and planning route algorithm are the key methods. Simulation results show that this system is efficiently built up by making use of the MapX component. The structure of the road network data and the algorithm is well designed to meet the system demand.
