【摘要】：当前我国高速公路交通安全形势十分严峻，已成为我国一个严重的社会问题，倘若我们不及时采取有效措施遏制交通事故的高发态势，高速公路交通安全状况将会逐年恶化，最终会严重制约我国高速公路的快速发展，危及人民的出行安全和财产安全。因此，如何有效地预防和减少交通事故、提高高速公路交通安全水平迫切需要得到解决。高速公路危险路段作为交通事故的多发地段，其交通事故数占总数的80%以上，因此危险路段的交通安全状态直接影响整个路网的交通安全水平,是交通安全治理的关键所在，因此本文针对高速公路危险路段，旨在建立一套能够集信息采集、处理、评价和发布一体化的交通安全预警系统，从而避免交通事故的发生，提高高速公路交通安全水平，保证人们的出行安全。本文首先分析总结了现有的交通安全预警系统框架理论研究，在此基础上,进一步深入细化并完善交通安全预警系统框架，提出预警系统应由交通安全预警信息采集子系统、基于GIS的交通安全预警信息处理子系统和交通安全预警信息发布子系统三个子系统构建而成，并对预警系统的设计原则、预警准则、警度分级等作了较为详细的阐述。然后，本文基于系统中预警模型所需要的预警信息，建立合理的预警信息采集指标体系，并针对上述采集指标，对信息采集的要求、采集方法和技术、信息采集检测器的布设等问题进行了分析研究。接着，，本文重点研究信息采集后数据处理技术，主要包括数据的自动汇总、数据的预处理、交通安全状态评价模型和数据库的构建，其中对交通安全状态的评价指标体系和评价方法展开了重点研究，构建了一个准确有效的交通安全评价指标体系和交通安全状态评价模型。最后，本文介绍了信息发布子系统的构成，以及如何合理发布预警信息、信息发布设施的布设，然后介绍了如何根据警度来发布相应的预警信息。论文中涉及到的研究内容、研究方法和研究结论，对高速公路危险路段交通安全管理与预警系统工程实施，提供一定的理论依据和技术指导，具有十分重要的现实意义和实际应用价值。
[Abstract]:At present, the situation of expressway traffic safety in our country is very severe and has become a serious social problem in our country. If we do not take effective measures in time to curb the high incidence of traffic accidents, the expressway traffic safety situation will deteriorate year by year. Finally, it will seriously restrict the rapid development of expressway in China and endanger the safety of people's travel and property. Therefore, how to effectively prevent and reduce traffic accidents and improve the level of expressway traffic safety needs to be solved urgently. As a traffic accident prone area, the number of traffic accidents in dangerous section of expressway accounts for more than 80% of the total. Therefore, the traffic safety state of the dangerous section directly affects the traffic safety level of the whole road network and is the key to the traffic safety management. Therefore, this paper aims at establishing a set of information collection and processing for the dangerous section of the highway. To evaluate and issue an integrated traffic safety early warning system so as to avoid traffic accidents and improve the level of highway traffic safety, First of all, this paper analyzes and summarizes the existing traffic safety early warning system framework theory research, on this basis, further refine and improve the traffic safety early warning system framework. The paper puts forward that the early warning system should be constructed by the traffic safety early warning information collection subsystem, the traffic safety early warning information processing subsystem based on GIS and the traffic safety early warning information issuing subsystem, and the design principles of the early warning system are also given. Then, based on the early warning information needed by the early warning model in the system, a reasonable collection index system of early warning information is established. The requirements of information collection, the method and technology of information collection, the layout of information collection detector and so on are analyzed and studied. Then, this paper focuses on the technology of data processing after information collection, which mainly includes the automatic collection of data. The preprocessing of data, the construction of traffic safety state evaluation model and database, and the research on the evaluation index system and evaluation method of traffic safety state are carried out. An accurate and effective evaluation index system of traffic safety and a traffic safety state evaluation model are constructed. Finally, this paper introduces the composition of the information release subsystem, and how to reasonably publish the early warning information and the layout of the information release facilities. Then it introduces how to release the corresponding early warning information according to the warning degree. The research contents, research methods and research conclusions involved in the paper are introduced, and the traffic safety management and early warning system engineering of dangerous sections of highway are implemented. It has very important practical significance and practical application value to provide certain theoretical basis and technical guidance.
