【摘要】：由于交通行业信息化领域缺乏统一信息化标准，使得交通行业构建了大量的异构信息系统，各系统间难以实现信息交换共享，孤岛现象明显。本文分析了当前交通信息化存在的问题，通过对SOA架构和GIS技术的研究，根据交通行业整理平台的数据需求和平台功能需求，按照“人、车、户、路”的交通管理对象是否具有空间位置的特征来确定了平台的数据边界，采用面向对象的设计方法完成对交通信息库的设计，引入GIS图层的管理模式，将交通信息数据叠加基础地形图，最终形成“交通一张图”。采用面向服务体系架构（SOA，Service-Oriented Architecture）对平台进行设计，本文将平台分为5层，详细介绍了数据层、共享服务层和应用展现层的详细功能。最后总结了研究过程中碰到的问题和解决思路。本文所设计的平台实现了跨平台的整合以及异构交通信息系统信息交换，降低开发成本和实施风险，，增加程序功能能的复用性。实现了传统数据共享方式向空间信息在线服务方式的转变，满足交通厅机关及直属单位、社会公众、政府其他部门的应用需求，大幅提高交通信息的共享能力。
[Abstract]:Due to the lack of uniform information standards in the field of information technology in the transportation industry, a large number of heterogeneous information systems have been constructed in the transportation industry, and it is difficult to realize information exchange and sharing among the systems, and the phenomenon of isolated islands is obvious. This paper analyzes the problems existing in the current traffic information, through the research of SOA architecture and GIS technology, according to the data demand and platform function demand of the transportation industry, according to "people, cars, households." Whether the traffic management object of "Road" has the characteristic of spatial location to determine the data boundary of the platform, the traffic information database is designed by using the object-oriented design method, and the management mode of GIS layer is introduced. The traffic information data is superimposed on the basic topographic map, and finally the "traffic one map" is formed. SOA is adopted as a service-oriented architecture. The platform is designed by Service-Oriented Architecture. In this paper, the platform is divided into five layers, and the data layer is introduced in detail. The detailed functions of the shared service layer and application presentation layer. Finally, the problems encountered in the research process and solutions are summarized. The platform designed in this paper realizes the integration of cross-platform and the information exchange of heterogeneous transportation information system, and reduces the development cost and implementation risk. Increase the reusability of program function. Realize the transformation from the traditional data sharing way to the spatial information online service mode, and meet the application needs of the traffic department, the directly affiliated units, the public and other government departments. Greatly improve the ability to share traffic information.
