摘要
在非平面道路网络空间概念模型和GDF逻辑数据模型基础上,提出了一种城市多模式交通网络及其连通关系的表达方法,以辅助各交通模式间连通关系的自动化实现,并为更具实用价值的公众多模式出行信息服务提供方法支持。
Based on the study of conceptual modeling for nonplanar road network and GDF logical model,this paper sets forward a representation approach to modeling the urban multi-model transportation network and connectivity relationships between different features in different modes,and presents the formal definition of the involved features and relationships.A practical demonstration illustrates the application advantage of the presented model.The model also can be used to assist the automation of connectivity for urban multi-model transportation networks,and provide an effective support on public traveling information service.
