利用动体视力检测仪,对沙漠公路行车途中汽车驾驶员进行包括静视力和动体视力在内的视觉特性的实地测试,并就获得的1004个有效样本的检测数据进行统计整理,对受测驾驶员静、动体视力总体情况及其与驾驶员年龄、驾龄、持续行车时间、检测时的气温等因素之间的关系进行分析研究。对驾驶员视觉特性的实测分析表明:沙漠公路受测驾驶员静视力和动体视力平均值分别为1.3和0.7;动体视力相对于静视力的平均下降幅度为44.75%,远高于绿洲地区。关联度分析也表明,驾驶员的年龄、驾龄、驾车时间以及测试温度4项因素对其静视力、动视力以及视力降幅均具有较强的相关性,关联度均在0.76以上。 The dynamic vision tester was used to carry out on-the-spot test of visual characteristics including static visual acuity and dynamic visual acuity of motorists on desert highway. The test data of 1004 effective samples obtained were statistically analyzed. Driver static and dynamic visual acuity overall situation and its relationship with the driver age, driving experience, driving time, the temperature of the test and other factors between the analysis. The visual analysis of the driver’s visual characteristics shows that the average static visual acuity and dynamic visual acuity of the driver on the desert highway are 1.3 and 0.7, respectively. The average visual acuity of the motor vehicle is decreased by 44.75%, much higher than that of the oasis. Correlation analysis also showed that the driver’s age, driving experience, driving time and test temperature of 4 factors on the static visual acuity, visual acuity and visual acuity have a strong correlation, the correlation was above 0.76.
