基于GIS的公交规划软件构架研究

GIS-based Transit Planning Software Framework

从公交规划的基本功能和需求特征着手 ,从基于 GIS的软件开发角度 ,探讨了公交规划软件的构架。之后对 GIS数据形成公交网络、GIS为公交规划功能提供的接口 ,以及利用 GIS实现有效的公交系统图形显示进行了描述。最后提出了基于 GIS的公交规划软件的总体功能 ,给出了软件开发实例。

First, based on analyzing functions of the basic transit planning and characteri stics of transit demand, this paper proposes the framework of transit planning f rom the viewpoint of the development of the GIS-based software. Then, the paper describes the ways to utilize GIS data to create transit network to provide int erfaces for transit planning, and to display an effective transit system. Finall y, whole functions of GIS-based transit planning software are proposed with an example, which has realized the integration of GIS to design framework of effici ent transit planning software.
