摘　　要：在介绍GIS、GIS-T的概念、GIS在ITS的作用、GIS系统结构发展的基础上确定采用B/S结构设计GIS,并设计了GIS的功能:数据采集、数据管理、空间分析和系统维护与刷新;设计了GIS-T的应用界面,这样的设计是合理和可行的,并已经用于兰州市ITS的建设中.文中最后还列举了GIS-T急需解决的问题.On the basis of the concept of geographical information systems (GIS), geographical information systems for transportation (GIS-T), the development history of system architecture of GIS, the architecture of GIS-T is designed based on Brower/Sever. The functions of GIS-T are also designed , which include four parts of function components : data input, data management, spatial analysis and system maintenance& data refreshment. The application interfaces of GIS-T are also designed. The result demonstrated our designed GIS-T is reasonable and practical. The design of GIS-T has been used in the project of Lanzhou ITS. At last, the imperative problems in GIS for ITS are provided.
