中文摘要：
交通系统具有时空动态特征，时象间关系复杂，多类应用共享相同的空间和实时交通流数据，多参照系统并存。为真实表达交通系统的动态特征和复杂关系，避免数据重复采集和管理，实现多参照系统、多类数据的集成和共享，提高数据综合使用价值，综合多类交通应用的共同特征，提出了一种支持移动对象的网络时空数据模型STMNMO。
英文摘要：
There are many complex topological and traffic relationship among traffic objects which have spatiotemporal dynamic characteristics.Many traffic information systems share the common spatial and traffic flow data.Geographic referencing system and more than one linear referencing system may be used in the same application.In this paper,a new Spatiotemporal Data Model Based on Network Including Moving Objects（STMNMO） is proposed,ln order to express the dynamic characteristics and sophisticated relationship in transportation networks,to avoid repeated collection and management,to share data from various applications or various referencing systems.As an integrate data model,it will generalize the common features of many kinds of traffic appilication,to make data integration and share.
