Namely , this system utilizes perfect gps combines gis of transportation and tele ? m industry broadened mobile communication network of gsm in china , with the help of data operation of gis and spatial analysis technology , this build up a conducting control system which put together transference conduct scientific management , harmonial operation and safety defence , it also strengthen the safety defence ability of some unforseseen hazard and so on 即利用成熟的gps全球卫星定位技术，结合gis - t交通地理信息系统，以及我国电信行业在全国所开通的gsm移动通讯网络，在gis的数据操作及空间分析技术的辅助下，建立集调度指挥、科学管理、协调运营以及安全防范为一体的指挥控制体系，并加强对不可预见之危险的安全防范能力等。
The trick is how best to combine satellite - positioning technology , laser range - finders , radar sensors and omni - directional cameras to gather enough data ? but not too much ? so the vehicle ' s software can figure out what is going on before hitting something or swerving onto the wrong side of the road 诀窍在于如何最大程度地将卫星定位技术、激光测距仪、雷达探测器以及全向照相机集合到一起，获取足够但总不会过多的数据，以便可以在车辆撞上某物或者驶到道路的错误一侧之前让软件计算出所处状况。
With the widespread uses of computer technology , satellites positioning technology , gis and mobile telecommunication technology , the 3g integrated - system has gotten a high speed development , as an important part of intelligent transportation system . this integrated - system has been studied intensively in this paper 随着计算机技术、卫星定位技术、地理信息系统和移动通信技术的广泛应用，作为智能交通系统重要组成部分的3g - is系统也得到了飞速的发展，本文对该系统进行了深入细致的研究。
