摘　　要：文章为研究山区高速公路弯道路段在不同转向、不同弯道半径条件下驾驶员视点分布的规律,采用Smart Eye Pro 5.7型非侵入式眼动仪记录了不同情况下驾驶员眼球运动的数据,并利用瞳孔直径、X和Y视角、注视次数百分数、注视时间百分比、平均注视时间等指标,对记录的数据进行分析。结果表明:弯道半径越小,驾驶员心理压力越大,且越关注弯道内侧;在左转弯条件下,驾驶员的心理压力和心理起伏都要比右转弯较大;弯道段的垂直注意力集中在正中偏下。In order to research the driver＇s viewpoint distribution pattern on different types of curved section of the highway in nlountainous area, the driver＇s eye movement data in different situations is recorded by Smart Eye Pro 5.7 non-intrusive eye tracking system. Then the recorded data is analyzed according to the indexes including pupil diameter, X,Y perspective, the percentage of fixation fre- quency, the percentage of fixation duration, and average fixation duration. The results show that the smaller the curve radius, the more the driver feels pressure, and the more the driver focuses on inside areas of the curve; when turning left, the driver feels worse than turning right~ when on curved sec- tion, the vertical attention focuses on the median offset areas.
