草原公路直线段路侧景观对驾驶员视觉特性的影响

 视觉系统是驾驶员获取行车信息的主要通道，而公路路侧景观是引起驾驶员视觉刺激的重要因素之一。以不同路侧景观的草原公路直线段作为研究对象，利用眼动仪采集5名驾驶员的眼动指标并进行分析。结果表明，驾驶员在景观相对复杂路段的瞳孔直径和扫视幅度较大，眨眼持续时间与注视持续时间较小；不同路侧景观对驾驶员的眨眼持续时间、注视持续时间、扫视幅度影响不显著；对驾驶员的瞳孔直径影响显著。本研究可为分析草原公路路侧景观对驾驶员疲劳的影响提供参考。

Effects of Prairie Highway Roadside Landscape of Straight Line Section on the Driver’s Visual Characteristics

The vision system is the main channel for the driver to obtain traffic information, and the highway roadside landscape is an important factor in the visual stimulus to the driver. With different roadside landscapes of the prairie highway straight line section, the eye movement indexes of 5 drivers are collected and analyzed by the eye tracker. The results show that the driver's pupil diameter and the saccade amplitude are larger, but the blink duration and the fixation duration are shorter in the relatively complex roadside landscape section. The effect of the different roadside landscapes on the driver's blink duration, the fixation duration and the saccade amplitude are not significant, but the effect on the driver's pupil diameter is significant. The results may provide a reference for studying the effect of the prairie highway roadside landscape on driver's fatigue.
