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。
In order to improve driving safety in the tunnel, the influence of different scale and different frequency of visual information on the driver’s speed perception is quantitatively analyzed. Using 3DMax to Make Highway Tunnel Simulation Model. Speed-sensing psychophysics experiments were conducted using E-prime software to investigate the effect of large, medium and small-scale information on the driver’s speed perception in low-light tunnel environments at frequencies from 0.1 Hz to 32 Hz. The experimental results show that high-frequency visual information (2 ~ 32 Hz) can significantly over-estimate the driver’s speed. Intermediate frequency visual information (0.4 ~ 1 Hz) and low-frequency visual information The degree of overestimation of speed is mesoscale information> large-scale information> small-scale information. Therefore, to ensure the traffic safety in the tunnel, we can start with the combination of multi-size and multi-frequency visual information.
