Abstract: This paper accounts for the concept and configuration of intelligent transportaion systems, and then shows our country’s reserachful actuality of intelligent transportaion systems and advanced traveler information systems in ITS. It introduces GPS, GIS and trunking communication system, and then expatiates the developing model of advanced traffic information systems in our country,i.e. GPS is selected to automatic vehicle location, GIS is choiced to operational platform of transportation information center, and trunking communication system is used to communication methods. It is considered that this model will be the best one on ATIS.

Key words: intelligent transportaion systems(ITS), advanaced traveler information systems (ATIS), global positioning systems (GPS), geographic information systems(GIS), trunking communication, dynamic route guidance system(DRGS)

摘要： 说明了智能交通系统的概念和组成，阐述了当前我国智能交通系统和智能交通系统中先进的交通信息系统的研究现状，介绍了智能交通系统中需要应用的GPS,GIS和集群通信系统，并详细说明了当前我国先进的交通信息系统的主要开发模式，即采用GPS全球定位系统进行车辆自动定位，采用GIS地理信息系统作为交通信息中心的操作平台，采用集群通信系统作为通信手段，并认为这将成为我国城市智能交通系统中ATIS开发的最佳模式。
