From the basic principles and composition of existing vehicle navigation system, combine Chinese Compass satellite navigation system. With comprehensive utilization of communications, control, GIS and other technologies. Offers a design of autonomous and center type compatible vehicle navigation system, and focus on the implementation scheme of control center and mobile terminal. The control center by collecting real-time traffic information, analysis and processing to form the optimal path program, mobile terminal get their appropriate guidance information according to location area, made urban traffic flow tend to the optimal distribution, reduce the time of vehicle stay on the road. It will effectively improve the urban traffic conditions, reduce traffic congestion.%从现有车辆导航系统的基本原理和组成出发,结合我国自主的北斗卫星导航系统,综合应用通信、控制、GIS等多种技术,提出了一种兼容自主式和中心式车辆导航系统的设计,并重点讨论了控制中心和移动终端的实现方案,控制中心通过采集实时交通信息,进行分析处理后形成最优的路径规划,移动终端根据自身所在的位置区域获取相应的诱导信息,使城市的交通流趋向最优分布,减少车辆在道路上的逗留时间,从而有效地改善城市交通状况,减少交通拥堵.
