摘　　要：本文提出一种基于GIS的面向多模式的城市公共交通网络数据及其拓扑关系的表达和集成模型研究,为多模式城市公共交通地理信息系统的应用和专门化信息服务的开发和实现提供了数据和关系支持。以广州市为例,数据模型涉及不同交通模式的网络系统,包括道路网络,公共汽车网络,地铁网络和步行网络等,并应用面向交通地理信息空间特征描述的面向对象建模方法实现不同交通网络的数据集成和拓扑关系表达。This paper focused on the study of multi-modal public transportation network data and topological relationships representations and integration based on Geographical Information System(GIS).This aimed to provide appropriate data and relationships to allow the development of specialised GIS-based applications and services.The data model was experimented in the city of Guangzhou.The data modal involved different transportation mode network systems,including street network,bus line network,metro network and walking network.An object-oriented modeling method,oriented to transportation geography information spatial characteristics representations,was applied to implement data integration and topological relationship representation of different transportation networks.
