城市慢行交通网络数据建模研究

城市慢行交通系统是现代城市交通系统的重要组成部分,随着多模式城市交通发展,建立便捷和高效的城市慢行交通网络系统成为现代城市解决交通问题和提升交通运行效率的关键措施。基于此,文中应用统一建模语言（UML）和地理标识语言（GML）建立城市慢行交通网络数据模型,提出一种统一的和一致性的交通地理要素定义和性质描述方法,并阐述基于GML的城市慢行交通网络的地理要素和关系表达。研究成果促进了城市交通地理数据的组织、表达、集成、共享和操作,对建立高效的城市慢行交通网络系统具有重要的理论价值。

Study on Urban Non-motorized Transportation Network Data Modeling

Urban non- motorized transportation system is the important component of modern urban transportation system. With the development of multi- modal transportation,it is the key measure to build a convenient and efficient urban non- motorized transportation system for modern cities to deal with traffic problem and improve traffic running efficiencies. Therefore,apply Unified M odeling Language（ UM L） and Geography M arkup Language（ GM L） to construct an urban non- motorized transportation network data model,and present an unified and consistent transportation geography features＇ definitions and the methods of their properties representation. As a result,describe the representation of the geography elements and their relationships in urban non- motorized transportation network based on GM L. The result in this paper promotes the organization,representation,integration,sharing and operation of urban transportation data,and has theoretic value for a high efficient transportation network system.
