摘要
智能交通系统 (ITS)的各种功能是以信息为中心展开的 ,因而信息应用是 ITS最为核心的研究内容之一。该文依托具有层次化特征的面向信息应用的 ITS体系结构 ,基于对 ITS的时空属性、媒介属性、层次属性、质量属性、存储属性、通讯属性、安全属性和主题属性等各种信息特征的分析 ,借鉴面向对象思想 ,提出了适用于 ITS信息交换的信息模型 ,该模型具有面向对象、自描述、自操作等特征 ,能有效地满足 ITS中不同层次信息交换的需求 ;另外还结合
All of the functions of Intelligent Transportation Systems (ITS) are based on information, so information application is a core component of ITS research. A layered, information application oriented ITS architecture was used to analyze ITS information attributes, such as time, space, medium, layer, quality, storage, communication, security and theme, to develop a data model for ITS information application with self description and self operation. An exchange mode was also discussed.
