在这项研究中，非侵入式眼动跟踪系统Smart Eye Pro被用来记录驾驶员在两种照明环境下驾驶高速公路隧道时的眼动参数。通过分析记录的眼动参数，研究了驾驶员的驾驶安全性。结果表明，亮度的急剧下降会导致驾驶员注视点的位置和持续时间发生变化。驾驶员对未知的公路隧道照明环境进行了连续的视觉探索，这体现了强烈的紧张感。隧道内部区域的亮度降低、均匀性降低和闪烁效应导致驾驶员瞳孔直径增加，驾驶员的视觉负荷随着瞳孔直径增加率的变化而增加。隧道侧墙照度越高，眼动参数越稳定;建议优化隧道照明环境的空间亮度分布，并在隧道洞口采用敞开式遮阳板，以达到节能和安全通行的目的。
In this study, the non-intrusive eye-tracking system Smart Eye Pro was used to record eye movement parameters while drivers were driving through a highway tunnel with two types of lighting environments. The driving safety of the drivers was studied by analyzing the recorded eye movement parameters. The results indicated that the sharp decrease in luminance would result in the change in the position and duration of the fixation point of the driver. The driver performed continuous visual exploration of the unknown highway tunnel lighting environment; this reflects a strong sense of tension. The decreasing luminance, its lower uniformity, and the flicker effect in the tunnel interior zone, resulted in the increase in the pupil diameter of the driver, and the visual load of the driver increased with the change in the rate of increase in the pupil diameter. The eye movement parameters were more stable in a lighting environment with higher luminance on the tunnel sidewall; the optimization of the spatial luminance distribution of the lighting environment and the use of open sun-screens in the entrance portal are recommended for energy saving and traffic safety in highway tunnels.
