公路隧道光环境信息感知及试验研究

Study on Light Environment Information Perception and Experiment Method of Highway Tunnel

为进一步认识公路隧道光环境的信息组成,探讨静态和动态条件下的隧道信息感知机制,首先,综述国内外公路隧道光环境信息与感知的最新研究成果,着重介绍构成公路隧道光环境的物质及其反映的信息。然后,探究人-车-路行驶环境中的动态信息感知,并开展静、动态信息感知的试验研究。研究结果表明:公路隧道光环境包含直接影响因素和间接影响因素;感知这些因素所反映的综合信息可分为静态和动态2种工况。作为人-车-路行驶环境,信息感知既牵涉到物理指标(物理量),也牵涉到人的主观反应即生物指标(生物量)。最后,通过分析研究信息感知机制,构建动态信息感知试验平台并开展试验研究,初步提出结合物理量和生物量交互的隧道光环境信息感知研究方法及评价指标。

In order to further understand the information composition of the light environment of highway tunnels and discuss the mechanism of tunnel information perception under static and dynamic conditions,firstly,the latest research results on the information and perception of light environment of highway tunnels in China and abroad are summarized,and the substances that constitute the light environment of highway tunnels and the information they reflect are emphatically introduced.And then,the dynamic information perception in man-car-road driving environment is explored,and the static and dynamic information perception experiment is carried out.The results show that:(1)The light environment of highway tunnel includes direct and indirect factors.(2)The comprehensive information reflected by these factors can be divided into static and dynamic conditions.As a human-vehicle-road driving environment,the information perception involves both physical indicators(physical quantities)and human subjective responses,namely biological indicators(biomass).Finally,by analyzing and studying information perception mechanism,a dynamic information perception test platform is constructed and experimental research is carried out,and a research method and evaluation index of tunnel light environment information perception combining physical quantity and biomass interaction is preliminarily proposed.
