【摘要】：驾驶员在行车过程中主要依靠视觉获取相关的道路交通信息。基于草原公路特殊的线形特点,通过在草原公路进行实驾试验,利用眼动仪采集驾驶员眼动指标。分别提取各驾驶员在不同半径平曲线路段行车时的试验数据,探讨驾驶员在草原公路平曲线段行车过程中的眼动规律,分析驾驶员的眼动特性与道路平曲线半径之间的关系。得到平曲线半径对驾驶员的注视持续时间和扫视幅度的影响非常显著,对眨眼持续时间的影响较为显著。驾驶员在小半径曲线行车时,注意力高度集中,紧张感较强;在大半径平曲线行车时,行车感较为舒适,心理较为放松的特点。建议可以适当合理增加不同半径的平曲线来调节驾驶员的驾驶状态,缓解驾驶疲劳。
[Abstract]:Drivers in the driving process mainly rely on visual access to relevant road traffic information. Based on the special linear characteristics of the grassland highway, the driver's eye movement index was collected by using the eye movement instrument through the actual driving test on the grassland highway. The experimental data of drivers driving in different radius curve sections were extracted respectively to discuss the eye movement law of drivers in the driving process of the steppe highway flat curve section and to analyze the relationship between the driver's eye movement characteristics and the road plane curve radius. The results show that the radius of the plane curve has a significant effect on the fixation duration and the scan amplitude of the driver, and on the duration of the blink. When driving with a small radius curve, the driver has the characteristics of high concentration and strong tension, while driving with a large radius and flat curve, the driving feeling is more comfortable and the mind is more relaxed. It is suggested that the flat curve with different radii can be properly increased to adjust driver's driving state and alleviate driving fatigue.
