中文摘要：

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。

英文摘要：

In the process of driving,the driver mainly depends on the visual access to the road traffic information. Based on the special linear characteristics of grassland highway,the driver of the driver＇ s eye movement is collected by using the eye tracker. Eye movement rules were extracted from the driver in the different radius of horizontal curve road traffic test data,of driver in grassland highway horizontal curve driving the process of analysis,the relationship between the driver＇ s eye movement characteristics and road horizontal curve radius. The influence of flat curve radius on the duration of the driver＇s fixation duration and the amplitude of the scan is very significant,and the effect of the horizontal curve radius on the blink duration is significant. Drivers in the small radius curve traffic,the attention of a strong sense of high concentration; in the large radius of flat curve traffic,driving feeling more comfortable,more relaxed psychological characteristics. It is suggested that the flat curve of different radius can be appropriately increased to adjust the driving state of the driver,so as to relieve the fatigue of the driver.
