中文摘要	以典型沙漠草原公路为试验路段,进行驾驶员行车眼动试验研究,分别采集在正常行驶状态下驾驶员的注视点坐标、注视持续时间和行驶车速,并转化为单位时间视觉兴趣区面积指标。通过对单位时间视觉兴趣区面积与曲线间直线段长度之间的模型建立和分析,得到沙漠草原公路曲线间短直线长度要保证行车6 s,理想长直线段长度为行车60 s,极限直线段长度为行车140 s,该值与国内外相关指标对比,指标在合理区间,为荒漠草原地区曲线间直线段指标的选取提供了理论依据。
英文摘要	The driver's eye movement experiments during driving are conducted on a typical desert grassland highway section,The coordinates of the point of view of the driver under normal driving conditions, the driver's continuous gazing time and the vehicle speed are collected, which are then converted into an area of visual interest per unit time. Through the correlation analysis and model establishment of the area of interest area and the length of the straight line section per unit time,the shortest straight line length between the curves of the desert grassland road must be guaranteed to drive for 6 s,the ideal length of long straight line segment is driving 60 s,and the length of the longest straight segment is driving 140 s,The values is in the reasonable rang compared with the domestic and foreign relative index,which can provide a theory for the selection of the index of the straight line between the curves in the desert grassland area.
