ITS交通数据管理的方法设计及技术实现

如何将现有的各种交通空间数据源,通过交通信息化中成熟的标准化数据交换格式的方法与技术,做到将多源、多格式的交通信息支持ITS的运行,已经成为摆在我国ITS建设面前迫在眉睫的问题。为此,在分析我国ITS交通数据的特点及其对数据库管理系统的要求的基础上,同时结合国内外的技术现状,探讨并提出了基于GDF4.0规范的交通数据管理模式。在方法设计中,对近来欧洲ITS中通用的导航规范GDF进行了研究、修改与设计,以适应我国的ITS信息平台的数据建设要求。同时,进行了部分的验证,表明了其技术的可行性。

Design Method and Implementation of ITS Traffic Data Management

How to use current and every kind of traffic information matttre standardized data exchanges format and technique to support ITS is an important and urgent task.For this, on the base of analyzing the characteristic of traffic data and the raguirement for database management, combined with the available technology both at home and abroad, a new traffic data management parttem is put forward on the base of GDF criterion. To work out design method suitable for ITS information platform in China, the authors study the navigation criterion GDF for ITS in Europe, and conduct verification test in order to indicate the feasibility of the technology.
