摘　　要：为了平衡道路资源利用率,缓解道路交通拥堵状况,通过研究GPS定位系统及GPRS通信系统,基于SIM100模块、GR-87模块和S3C2410A微处理器,采用嵌入式系统技术设计了一种实时交通信息车载导航终端,用于接收城市道路实时交通信息。通信网络采用GPRS技术,信息服务中心采用公网固定IP组网方式。电子地图数据采用TAB格式存储,数据采用交通及出行者信息(TTI)经交通报文编码。最后,基于MiniGUI图形用户界面软件包在ARM-Linux操作系统上显示地图,并以不同颜色标注实时路况信息。实验结果显示移动目标定位准确,界面显示流畅。In order to balance the road usage and reduce the traffic jam,a new real-time traffic information navigation terminal is designed based on the research of GPS and GPRS and is used to receive the real-time traffic information of city.The terminal is designed using the embedded system technology and is made up of SIM100 module,GR-87 module and S3C2410A CPU.GPRS is used as the technology of communication and the server of information center is allocated a stable public network IP.The map data is stored in TAB format and is coded according to TTI（traffic and traveler information） message.At last,the map is showed in ARM-Linux OS using MiniGUI library and the real time traffic information is marked on it.The result shows that automobile is positioned correctly and map is shown fluently.
