隧道进出口路面结冰积雪和能见度实时预警研究

Real Time Early Warning of Ice and Snow and Visibility at Entrance and Exit of Tunnel

关于隧道进出口安全问题,现有技术主要是对于整条路段的天气进行区域性判断分析得出隧道公路信息,是基于区域性数据的分析,而不是对于隧道公路路面实际情况的实时检测,而且现有技术无法对于隧道公路情况进行实时检测、实时管控。隧道进出口预警系统是一个针对于路面能见度与结冰积雪的安全预警系统,包括数据处理系统、能见度监测系统、积雪结冰监测系统、预警发布系统。通过预警发布系统向驾驶员发布预警信息。通过模型实验研究表明,该系统在多种不利天气的模拟下,均能准确地检测,及时预警,以及改变隧道进出口渐变灯的亮度。本系统能够对公路隧道路面能见度与路面实际状况进行实时监测、即时反馈、及时预警,能够保证隧道进出口过渡段的行车安全。

With regard to the safety at the entrance and exit of tunnel,the existing technology is mainly to analyze the weather of the whole section by regional analysis to get the information of the tunnel highway,which is based on the analysis of the regional data and cannot realize real time detection and management of the actual situation of the tunnel road surface.The early warning system for entrance and exit of tunnel is a safety early warning system for conditions of road visibility and snow and ice freezing,which comprises of data processing system,visibility monitoring system,snow icing monitoring system and early warning and publishing system.Early warning information is released to drivers through the system.After experiments by models it is found that the system can precisely detect and release early warnings under various unfavorable weather conditions and can change the brightness of lights at the inlet and outlet of the tunnel.This system can carry out real-time monitoring,real-time feedback and timely warning of road tunnel visibility and the actual conditions of the highway tunnel,and can ensure the traffic safety at the transition section of the tunnel entrance and exit.
