【摘要】：受城市用地限制,简单扩建地面道路的方式已无法满足日益增长的交通需求,尤其是在沿海、沿江地区,为适应经济快速发展的需要,大型桥梁隧道正渐渐成为城市道路的重要构成部分。桥梁隧道交通相对于城市道路,是在全封闭环境下运行,交通环境的不同造成了车辆行驶特性的差异。桥梁隧道中交通量较大,交通流的快速通过易诱发交通事件,若不能及时检测到事件的发生并做出快速反应对交通流进行管控,会有大量的车辆进入隧道或聚集在事故点,不利于车辆的疏散和对事件的救援,并会导致事件的进一步扩散。因此在桥梁隧道交通管控系统中,需要有高效的交通事件检测算法,使系统能够及时的检测到事件发生,结合预案联动管理机制和成熟、稳定、高实时性的工业组态技术使系统对事件做出快速反应,在防止事件扩散的同时将其影响降至最低,为后续事件处理和救援工作的展开提供了条件。桥梁隧道所涉及的交通设备较多,管控系统相对复杂,要求系统有较高的实时性和稳定性,因此需要有特殊的系统实现管控,以保障桥隧交通安全、畅通。本论文在查阅大量文献和到桥梁隧道交通现场调研的基础上,将工业组态技术引入到交通信号控制领域。在深入研究桥梁隧道交通特性和国内外桥梁隧道交通管控系统的基础上,结合桥梁隧道交通的实际需求,在满足稳定、易于维护和管理、经济实用等要求的基础上,设计集信息采集、数据处理及信息发布、信号控制、交通数据展示、故障报警与预案管理、日志管理及基础设备维护等功能于一体的大型桥梁隧道交通综合管控系统,提高各系统间的数据协同和共享水平。最后结合大连市南部滨海大道桥梁隧道交通环境的实际需求开发大型桥梁隧道交通综合管控系统。该系统使用工业组态技术,确保系统实时、稳定、高效运行,通过实地部署和后期对运行数据的统计、分析,处理结果验证了大型桥梁隧道交通综合管控系统的可行性和有效性,可以使管理部门实现高效、实时掌控桥梁隧道交通的运行状态,提升桥梁隧道交通管控效率,保障交通安全、高效运行,同时对于促进桥梁隧道交通综合管控系统的发展、完善具有十分重要的意义。
[Abstract]:Limited by urban land, the simple expansion of the ground roads can no longer meet the increasing traffic demand, especially in coastal areas, along the Yangtze River, to meet the needs of rapid economic development. Large-scale bridge tunnels are gradually becoming an important part of urban roads. Compared with urban roads, the traffic of bridge tunnels is operated in a completely closed environment. The difference of traffic environment causes the difference of vehicle driving characteristics. The traffic volume in bridge tunnel is large, and the rapid passage of traffic flow can easily induce traffic events. If the incident can not be detected in time and make a rapid response to traffic flow control, there will be a large number of vehicles entering the tunnel or gathering in the accident site, which is not conducive to the evacuation of vehicles and the rescue of the incident. And will lead to the further spread of events, so in the bridge tunnel traffic control system, there is a need for efficient traffic incident detection algorithm, so that the system can detect events in time. Combined with the integrated planning management mechanism and mature, stable, high real-time industrial configuration technology, the system makes a rapid response to events, while preventing the spread of events to minimize its impact. The bridge tunnel involves more traffic equipment, the control system is relatively complex, and requires the system to have high real-time and stability. Therefore, it is necessary to have a special system to achieve control in order to ensure the safety and smooth traffic of bridge and tunnel. This paper is based on consulting a large number of documents and investigating the traffic site of bridge and tunnel. The industrial configuration technology is introduced into the traffic signal control field. On the basis of deeply studying the traffic characteristics of bridge tunnel and the traffic control system of bridge tunnel at home and abroad, the actual demand of bridge tunnel traffic is combined. On the basis of meeting the requirements of stability, easy maintenance and management, economic and practical, the design sets information collection, data processing and information release, signal control, traffic data display, fault alarm and plan management. Log management and basic equipment maintenance and other functions in one of the large-scale bridge tunnel traffic control system. Finally, combining with the actual demand of the traffic environment of Binhai Avenue bridge tunnel in south Dalian, the integrated control system of large-scale bridge tunnel traffic is developed. The system uses industrial configuration technology. Art. Ensure the real-time, stable and efficient operation of the system, through the field deployment and post-operation data statistics, analysis, processing results verify the feasibility and effectiveness of the large-scale bridge tunnel traffic control system. Can make the management department to achieve efficient, real-time control of bridge tunnel traffic operation, improve the bridge tunnel traffic control efficiency, ensure traffic safety, efficient operation. At the same time, it is of great significance to promote the development of bridge tunnel traffic control system.
