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。
The natural environment in the plateau is different from that in the plains, which makes the conditions of the plains on the plain are relatively complex. The impact on the drivers is also very significant. In order to study the visual characteristics of the drivers in the hypoxia area, The use of vision detector on the long-running vehicles for field testing. Through the analysis of measured data, the average static and dynamic visual acuity of drivers on plateau is 1.18 and 0.59, respectively. The average reduction of dynamic visual acuity relative to static vision is 49.62%, which is higher than oasis highway and desert highway. Correlation analysis shows that: the driver characteristics and altitude, age, driving experience, continuous driving time, and the degree of correlation are more than 0.73.
