中文摘要：

交通地理数据特征的有效表达是交通网络研究的基础理论问题之一。通过面向对象技术和UML语义扩展机制，从分析交通地理实体及关系的基本特征和内涵出发，提出交通地理数据多样性特征集成化架构，进一步建立统一的语义表达基准，提供丰富的交通语境和一致性语义定义与特征描述方法，支持在不同拓扑条件下交通地理数据体现出来的不同性质特征的有效表达，克服单纯地从地学或计算机表达的角度出发在交通地理数据特征表达的不足，促进具有多样性特征的交通地理数据的协调可视化、交互分析和共享。

英文摘要：

To implement effective representation of transport geographic data characteristics is one of the basic theory issues of the trans-port network studies. Through object-oriented technologies and UML semantic extension mechanism,beginning from analysis of basic characteristics and meaning of geographic entities and their relationships,propose an integrated frame of transport geographic data multiple characteristics. Further build a uniform semantic representation benchmark to provide rich transport context and methods of consistent se-mantic definitions and characteristics depiction,supporting the effective representations of transport geographic data multiple characteristics derived from various topological conditions,and overcome the shortages of the representation of transport geographic data multiple charac-teristics simply based on geographical or computer＆#39;s points of view. The outcome should promote the cooperated visualization,mutual-a-nalysis share of transport geographic data with multiple characteristics.
