中文摘要：
广州市ITS共用信息平台是广州市智能交通系统（ITS）信息共享、交换和信息服务的核心，而软件体系结构决定着共用信息平台的总体性能．根据广州市ITS建设的现状和未来发展的需求，提出了平台软件体系结构设计的原则．并在该原则的指导下，提出并深入研究了包括逻辑结构、软件模块结构和软件部署结构的平台软件体系结构．文中所提出的软件体系结构已在广州市ITS共用信息平台示范工程中进行了应用．示范工程建设的成果表明：这种体系结构能有效地连接当前广州市多个已建ITS子系统，实现各系统数据共享和交换，同时具备良好的扩展性，能满足ITS不断发展的需求．
英文摘要：
ITS common information platform is the core of the information share, exchange and information service of Intelligent Transportation System （ITS） in Guangzhou. And software system structure can affect performance of the platform. This paper advanced the principles of the platform software structure design, according to the construction situation and development demands of ITS in Guangzhou. And with the guidance of the principles, the software system structure, including logic structure, software configuring structure and software deployment structure, were promoted and studied deeply. The software structure promoted, has been applied in the construction of ITS common information platform in Guangzhou. And the achievement of the demonstration project show that the software structure can realize the interconnection of the existing ITS subsystem effectively, and can be extended easily to meet the requirements of the ITS development in the future.
