摘要
为提高隧道内的行车安全性,定量分析隧道内不同尺度、不同频率的视觉信息对驾驶员车速感知的影响。利用3DMax软件制作公路隧道内仿真模型。利用E-prime软件进行车速感知心理物理试验,分别研究大中小尺度信息在频率为0.1~32 Hz的情况下,对低照度隧道环境中的驾驶员的速度感知的影响。试验结果显示：高频视觉信息（2~32 Hz）会使驾驶员显著高估速度,中频视觉信息（0.4~1 Hz）和低频视觉信息（0.1~0.2 Hz）会使驾驶员显著低估速度;高估速度的程度为中尺度信息〉大尺度信息〉小尺度信息。因此,保障隧道内行车安全,可从多尺寸多频率的视觉信息的组合设置着手。
It was held by the authors that in order to improve traffic safety in tunnels,a quantitative analysis shoud be made for effects of both scale and frequency of visual information on driver＇s vehicle speed perception. 3DMax software was used to build a simulation model for freeway tunnels. E-prime software was used to carry out speed perception psychophysical experiments. The results indicate that the high frequency of visual information（2-32 Hz） makes the driver overestimate significantly the speed,both middle frequency of visual information（0.4-1 Hz） and low-frequency visual information（0.1-0.2 Hz） make the driver underestimate the speed significantly,and that a right combination of multi-frequency and multi-scale visual information will contribute greatly to improving traffic safety in tunnels.
