摘要: 社会中的很多空间现象,如交通、信息交流和生活消费品的运输等都是线性的。在ARC INFO地理信息系统(GIS)中,这些线性现象经过组织和处理,能够建立成网络及其数据库。从而可用来解决资源的合理分配和流动、交通运输中的最佳路线选择等问题。

Abstract: There are many linear phenomena in our daily life. They are traffic, communication, and goods transportation etc.These phenomena can be organized into linear networks in ARC/INFO Geographic Information System (GIS). This paper describes how to Prepare, and create the City of Beijing traffic network by using ARC/INFO GIS.PATHFINDING and ALLOCATE are two functions in ARC/INFO NETWORK. The best path can be found between an origin and a destination, and the most efficient movement of resources can be allocated by using the two functions.After the network coverage (a file of traffic map in ARC/INFO GIS) processed, the network database has been created.The different applications of the network can be done.Finally, the modelling of traffic network has been established.It is not only for extending streets, also for building a new traffic route very efficientlly.
