基于特征和超图理论的交通网络数据模型

Data Model for Traffic Network Based on Features and Super-map Theory

分析了目前国际上流行的五种交通网络数据模型的优缺点,然后提出了基于车道和中心线的交通网络数据模型。该数据模型以特征和超图模型理论为基础,既保留了拓扑结构的优越性,又有利于数据以特征的方式进行存储和管理。最后,把这种基于特征和超图模型的交通网络数据模型应用于中山市道路普查系统,用于管理复杂的、与道路相关的各种数据。

The five popular data model for traffic network in the world are analyzed in this paper. Then, a data model for traffic network based on lane features and center-line features is established. The data model depends on features and super-map theory as a basis. It not only holds advantages of topology, but also manages data by feature theory. At last, the data model is applied to route information system of Zhongshan City and used to manage intricate data about route.
