摘　　要：针对城际间广域智能交通系统发展所面临的多源异构数据的问题,根据城际交通综合信息平台的功能和特点,提出了采用B/W/S(Browser/WebServer/DatabaseServer)结构的城际交通综合信息平台。其中,应用了虚拟数据仓库和可扩展标识语言(eXtensibleMarkupLanguage,XML)技术,将多类数据以XML的形式从各异构数据源中迁移到数据库服务器上,建立相应的虚拟数据仓库,以解决分布、异构环境下数据共享及利用的问题。利用XML实现数据共享的技术途径,进行实际应用开发。该平台具有良好的扩展性、开放性和灵活性。The Inter-City Transport Integrated Information Platform (IC-TIIP) was designed to provide a broad spectrum of operational data from multiple sources strategically placed thoughout the system as the key input to the Inter-City Intelligent Transport System. A new architecture developed for the IC-TIIP was developed based on a virtual data warehouse and eXtensible Markup Language (XML). This paper describes the IC-TIIP system architecture in which the virtual data warehouse receives a wide range of data from many sources and analyzes the function and advantages of the virtual data warehouse based on the complex real-time distribution characteristics of the IC-TIIP. The results show that this open, flexible platform has good expandability so that it can be used for transportation systems.
