【摘要】：近年来,随着我国突飞猛进的基础设施建设,经济发展带动汽车保有量不断上升,货运批次和总量也年年攀升,致使高速公路的承载的安全生产压力与日俱增。尤其是在高速公路长下坡路段极易发生交通安全事故,造成重大经济损失和不良社会舆情,成为当今高速管理者亟待解决的问题。在调阅大量国内外相关研究资料的基础上,本文结合永春长下坡路段的历史事故情况,分析了造成交通安全事故的因素(包括司机、车辆、道路、气候、技术、经济、管理等),提出了一套由前端监控设备和后端系统软件共同组成闭环监控的解决方案,以缓解高速公路长下坡路段交通安全压力。通过对交通安全预警及应急处置系统的总体设计,本文分析该系统包含的关键技术和技术路线。技术路线包括P2SP流媒体直播系统和面向服务的体系等两大软件架构;高清视频监控系统、卡口监控系统、预警发布系统等三大设备架构;本文经过详细设计和周密实施,提出了沿线因地制宜的联动解决方案;系统通过后端软件联动控制及数据分析,向前端司机发布预警信息,为管理者提供决策参考。根据系统建成一年后的相关运行数据,从预警、联动、处置等功能方面和警情发现、违章数据、交通事故、人员伤亡、经济损失等效益方面,分析了案例工程的建设成效。本系统视频事件自动检测功能缩短了接处警时间,全系统统一管理使预警发布范围更广,现场联动测速功能严厉打击超速、变道等违法违规行为,提高道路安全性能。该长下坡路段未发生人员伤亡的交通事故,减少了直接经济损失,社会反映良好。系统达到了积极预防、快速发现、联动响应、有效处置的预警及应急处置功效,完成了有效降低一次事故、大幅减少二次事故的建设目标。
[Abstract]:In recent years, with the rapid development of infrastructure construction in China, the economic development has led to a continuous increase in the number of vehicles, cargo batches and the total volume is also rising year by year. Especially in the long downhill section of freeway, traffic safety accidents are easy to occur, resulting in significant economic losses and bad social public opinion. On the basis of reading a large number of domestic and foreign related research data, this paper combined with the Yongchun long downhill section of the historical accident situation. The causes of traffic safety accidents (including drivers, vehicles, roads, climate, technology, economy, management, etc.) are analyzed. In this paper, a solution of closed-loop monitoring is proposed, which is composed of front-end monitoring equipment and back-end system software. In order to alleviate the traffic safety pressure on the long downhill section of expressway, the overall design of the traffic safety early warning and emergency disposal system is adopted. This paper analyzes the key technologies and technical routes of the system, including P2SP streaming streaming system and service-oriented architecture. High-definition video surveillance system, bayonet monitoring system, early warning release system and other three equipment architecture; After detailed design and careful implementation, this paper puts forward the solution of the linkage according to the local conditions along the route; The system through the back-end software linkage control and data analysis, to front-end drivers issued early warning information, for managers to provide decision-making reference. According to the system one year after the completion of the relevant operation data, from early warning, linkage. Disposal and other functional and police situation detection, violation of the data, traffic accidents, casualties, economic losses and other benefits. This paper analyzes the construction effect of case engineering. The automatic detection function of video events in this system shortens the time of receiving and handling police, the whole system unified management makes the range of early warning and issue more extensive, and the field linkage speed measurement function severely crack down on speeding. Change of track and other illegal acts to improve road safety performance. The long downhill road no casualties of traffic accidents, reduce direct economic losses, good social response. The system has achieved positive prevention, rapid detection. Linkage response, early warning and emergency response of effective disposal have achieved the construction goal of effectively reducing one accident and greatly reducing secondary accident.
