为分析驾驶员因高原环境影响而表现出的生理和心理特性,采用驾驶适宜性检测仪器,在高原公路沿线选定的测试点,针对过往驾驶员的特性指标进行现场测试。测试结果显示:高原公路驾驶员各项生理心理特性总体处于一般水平,其中,较差的是反应能力和判断能力;随着海拔增高,静视力和动视力显著降低,速度估计时间、反应时间、误反应次数、处置判断错误次数等指标均明显上升。关联分析表明:各特性指标与高原公路海拔、驾驶员年龄、驾驶时间等3个因素均有较强的关联性,关联度依次为海拔>年龄>驾驶时间。与不同环境地区相比,高原地区公路驾驶员总体表现出反应相对迟钝的特征。
In order to analyze the physiological and psychological characteristics of the driver due to the plateau environment, a driver suitability test instrument was used to test the past driver’s characteristic indexes on selected test points along the plateau road. The test results showed that all the physiological and psychological characteristics of drivers on the plateau were generally at the general level, of which the poor were the response ability and the judgment ability. With the elevation increasing, the static visual acuity and visual acuity decreased significantly, the speed estimation time, reaction time, The number of false reactions and the number of misjudgments of disposal were significantly increased. Correlation analysis shows that each index has strong correlation with altitude, driver’s age and driving time on the plateau, with the correlations being altitude> age> driving time. Compared with different environmental regions, highway drivers in the plateau generally showed a relatively slow response characteristics.
