中文摘要：

高原地区自然环境有别于平原地区,使得高原公路相对平原公路的条件复杂,其对驾驶人员的影响也非常显著,为对高原低氧地区驾驶员视觉特性进行研究,选取不同海拔为试验点,利用视力检测仪对长期行驶的车辆进行实地测试。通过对实测数据分析得出：高原公路驾驶员的静视力和动视力的平均值分别为1.18和0.59;动视力相对于静视力的平均下降福度为49.62%,高于绿洲公路和沙漠公路。关联度分析表明：驾驶员特性与海拔、年龄、驾龄、连续驾驶时间有关,并且关联度均为0.73以上。

英文摘要：

Because of the natural environment of the plateau region are different from the plain,the highway condition of the plateau is very complex,and the influence of the highway is very significant.,In order to study the visual characteristics of high altitude driver,select different altitude test,field test for long-term running of vehicles using eyesight detecting instrument.Through the analysis on the measured data,drivers static vision and dynamic vision of average were 1.18 and 0.59;dynamic visual acuity relative to static eyesight decline in average luck for 49.62%,far higher than the Oasis Road and desert highway.Correlation analysis showed that the driver characteristics and altitude,age,driving age,continuous driving time are related,and associate degree above 0.73.
