【摘要】：随着我国经济的不断飞速发展,高速公路的覆盖范围也越来越广,但交通事故的发生概率也随之增加。特别是在灾害天气下,交通事故频发,不仅造成了重大的经济损失也威胁着生命安全,现己成为行车安全的重大隐患之一。论文依托《基于公路交通传感网信息检测·挖掘·汇聚·发布与辅助决策系统示范》《省域智能交通运输信息云服务平台示范工程》等示范工程,在研究国内外灾害天气以及限速控制大量文献的基础上,对灾害天气高速公路限速控制方法与系统进行了一定程度的研究。论文分析了不同车速对驾驶员和车辆的影响以及车速和安全行驶的关系。在灾害天气和交通安全方面主要是针对降雨、雾天以及冰雪天气下对交通安全的影响来分析。分析了恶劣天气(雨、雾、冰雪)下高速公路的安全限速问题,分析比较了降雨环境AASHTO和NCHRP两种停车视距模型。研究了雾是如何在高速公路沿线形成的以及其特点。利用灾害天气对道路行驶安全的影响,采用基于停车视距的数学推导方法计算出最高的限速值,并给出了相应的限速标准建议值。比较分析了我国现有的高速公路限速标准,讨论了不同限速标准的有效性。研究了高速公路可变限速的基本思想以及作用原理。对交通状况进行建模,研究了交通数据原语的传输简单运输管理框架(STMF),分析了管理信息结构(SMI),交通管理信息库(TMIB),简单网络管理协议(SNMP),运输管理协议(STMP)。论文在实验室原有研究的基础上构建了灾害天气限速预警控制系统架构,利用Web Service等技术,系统可以调看视频,根据采集的高速公路图像检测能见度,对异常情况进行报警,并通过终端及时发布各种有效信息。综上所述,论文研究成果有效可信,具有重要的研究意义和应用价值。其主要创新点包括以下几个方面：·利用基于停车视距的数学推导方法计算出灾害天气下的最高限速值,并给出了相应的限速标准建议值。根据高速公路的实际情况分析比较了在降雨环境下的AASHTO和NCHRP两种停车视距模型。·研究了我国现有的高速公路限速标准和可变限速控制方法。·研究了交通数据原语的传输简单运输管理框架(STMF),构建了灾害天气限速预警控制系统架构。
[Abstract]:With the rapid development of China's economy, the coverage of the highway is becoming more and more wide, but the probability of traffic accidents is also increasing. Especially in disaster weather, frequent traffic accidents not only cause significant economic losses, but also threaten the safety of life. Now it has become one of the major hidden dangers of traffic safety. Based on the "road traffic information detection based on sensor network and mining - issued together and aided decision system" demonstration "provincial intelligent transportation information service platform demonstration project" demonstration project, in the domestic and foreign research and disaster weather limit control a large number of documents on the basis of the disaster weather freeway speed limit control method and system to a certain degree of research. The paper analyzes the influence of different speed on drivers and vehicles as well as the relationship between speed and safe driving. In the area of disaster weather and traffic safety, the effects of rain, fog and ice and snow on traffic safety are analyzed. The safety speed limit of freeway in bad weather (rain, fog, ice and snow) is analyzed, and two parking sight distance models are compared and compared with the rainfall environment AASHTO and NCHRP. This paper studies how fog is formed along the highway and its characteristics. Based on the influence of disaster weather on road running safety, the maximum speed limit value is calculated by the mathematical deduction method based on stopping sight distance, and the corresponding recommended speed limit standard is given. The current speed limit standard of Expressway in China is compared and analyzed, and the validity of different speed limit standards is discussed. The basic idea and principle of variable speed limit of freeway are studied. The traffic condition is modeled, and the transportation simple transport management framework (STMF) is studied. The management information structure (SMI), traffic management information base (TMIB), simple network management protocol (SNMP) and transport management protocol (STMP) are analyzed. The construction of the disaster weather warning control system architecture based on the speed limit on the original research laboratory, using Web Service technology, the system can watch the video, according to the highway visibility acquisition image detection, alarm for abnormal situation, and the timely release of all kinds of effective information terminal. To sum up, the research results of the paper are effective and credible, and have important research significance and application value. The main points of innovation include the following aspects: by using the mathematical deduction method based on stopping sight distance, we calculate the maximum speed limit under disaster weather, and give the corresponding speed limit standard recommended value. According to the actual situation of the expressway, the two parking sight distance models of AASHTO and NCHRP under the rainfall environment are analyzed and compared. The current speed limit standard and variable speed control method of Expressway in China are studied. In this paper, the simple transport management framework (STMF) for traffic data primitives is studied, and the framework of the speed - warning control system for disaster weather is constructed.
