摘要
通过系统分析城市交通的现状，提出了城市交通地理信息系统的网络结构模型，并推导出交通网络流数学模型，作为GIS系统的空间分析子模块，挂接到Geostar中，实现了城市交通地理信息系统原型，模型的研究并给出了武汉市建成区的一个实例．
By systematic analysis of the actuality of the urban transportation, this paper comes up with structural model for Urban Geographic Information System for Transportation (GIS-T), deduces mathematical model for the network flow of transportation; and the latter, considered as the spatial analysis system of GIS, linked with the software of GeoStar, ls adopted to realize the prototype of GIS-T, with the example of application to constructed District, Wuhan City.
