摘　　要：为提高高海拔地区公路平曲线路段交通安全,进行驾驶员疲劳测试试验。采用心率血氧测试仪、非接触式光电速度传感仪等仪器采集驾驶员在高海拔地区一级公路平曲线路段行驶过程中的心率血氧数据与汽车运行速度。分析驾驶员在该路段行驶过程中的驾驶疲劳特性,建立了驾驶疲劳度与平曲线曲率变化率之间的关系模型。试验结果表明,在高海拔地区长直路段或大半径圆曲线后接曲率变化率为0.06(°)/m或半径为800 m的圆曲线可有效缓解驾驶员驾驶疲劳。Driver fatigue is tested by experiments to ensure operational safety in horizontal curve section of highway in high-altitude area. A driver＇s heart rate,oximetry and the vehicle speed arecollected by a heart rate tester and a non-contact photoelectric speed sensor as the driver is driving in horizontal curve section of highway in high-altitude area. The driver＇s fatigue behavior in the section is analyzed,and a relational model of the driver＇s fatigue degree and the change rate of curvature is established. Experimental results show that a long straight section or a large radius circle curve followed by a circular curve with the change rate of curvature of 0.06（°）/m or the radius of 800 m in high-altitude area can relieve driver＇s driving fatigue effectively.
