【摘要】：随着我国交通信息化建设的推进，近年来交通监控已成为高速公路智能交通系统（ITS）的不可或缺部分。针对高速公路异构ITS集成与交通监控数据共享问题，通过扩展《交通信息基础数据元集》标准（编号JT/T697），形成了一套交通监控数据元，通过提取数据元语义建立了交通监控数据本体。在此基础上，搭建了适应于我国高速公路交通监控数据共享的本体映射与推理查询平台框架，并针对西安市城际高速公路网搭建了基于JBoss的路网交通监控系统网站。这些研究成果可应用于我国高速公路ITS集成中，用于实现异构ITS对多源交通监控数据的一致性理解和充分共享，在我国高速公路信息化建设中具有重要的应用价值。具体而言，论文的主要研究工作如下： (1)在对交通数据元标准JT/T697进行解读与语义分析的基础上，总结了交通监控数据元的补充需求；从动态数据和静态数据两个方面分析了高速公路的交通监控数据，设计了一套适用于交通监控的交通数据元，并将交通监控数据以交通监控数据元的形式进行语义提取与本体建模。 (2)搭建了一个适应于我国高速交通监控数据的本体映射和推理查询平台框架并且验证技术的可行性，从交通监控数据的分析、本体的映射规则设计、本体的推理查询实现三个方面总结了高速公路网监控数据本体映射与推理查询的方法。 (3)利用高速公路网监控数据本体映射与推理查询的结果，以当前较为成熟的J2EE架构应用服务器JBoss为开发平台，开发了以西安城域高速公路交通监控数据为上层应用实例的交通监控系统门户网站，进而验证了集成平台的技术实现可行性。
[Abstract]:With the development of traffic information construction in China, traffic monitoring has become an indispensable part of the Intelligent Transportation system (ITS) in recent years.Aiming at the problem of heterogeneous ITS integration and traffic monitoring data sharing in freeway, a set of traffic monitoring data elements is formed by extending the Standard of basic data set of Traffic Information (JT / T697).Traffic monitoring data ontology is established by extracting data element semantics.On this basis, the ontology mapping and reasoning query platform framework suitable for expressway traffic monitoring data sharing in China is built, and the network traffic monitoring system website based on JBoss is built for Xi'an intercity expressway network.These research results can be applied to the expressway ITS integration in China, and can be used to realize the consistent understanding and full sharing of heterogeneous ITS to the multi-source traffic monitoring data. It has important application value in the highway information construction of our country.Specifically, the main research work of the thesis is as follows:1) based on the interpretation and semantic analysis of traffic data metadata standard (JT/T697), the supplementary demand of traffic monitoring data element is summarized, and the traffic monitoring data of freeway is analyzed from two aspects: dynamic data and static data.A set of traffic data elements suitable for traffic monitoring is designed, and the traffic monitoring data is extracted by semantic and ontology modeling in the form of traffic monitoring data elements.(2) A framework of ontology mapping and reasoning query platform for high-speed traffic monitoring data in China is set up and the feasibility of the technology is verified. From the analysis of traffic monitoring data, the design of ontology mapping rules,The methods of ontology mapping and reasoning query of highway network monitoring data are summarized in three aspects of ontology query implementation.Based on the results of ontology mapping and reasoning query of highway network monitoring data, the application server JBoss, which is currently mature in J2EE architecture, is used as the development platform.Based on the traffic monitoring data of Xi'an City Expressway, a traffic monitoring system portal is developed, which verifies the feasibility of the integrated platform.
