摘　　要：详细讨论了交通地理信息系统的类型、数据模型以及空间分析功能 ;结合中国西北地区的交通地理信息系统的具体开发实例 ,阐述了交通地理信息系统中弧段 -结点拓扑关系、动态分段等原理 ,并探讨了多种查询手段的综合应用、道路里程桩号系统和道路描述系统等问题。Geographic Information System for Transportation(GIS T) has been widely used in the designing and management of roads network and other facilities. In this paper the types, methodologies, data models and spatial analysis of GIS T are introduced in detail. The principle based on arc-node topological relation and dynamic segment are expatiated by a development instance. Some problems, such as building rich query, the mileage mark system and the road descriptive system, are also discussed by a sample of GIS T for Northwestern China. The application instance of GIS T showed that it would greatly improve the convenience and efficiency of the transportation vocation.
