基于驾驶适宜性检测的沙漠公路驾驶员视觉特性分析

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。

Visual Characteristics Analysis of Drivers on the Desert Highway Based on Driving Suitability Test

By use of vision test device for moving objects,the static vision and dynamic vision of drivers driving on the desert highway are tested,1 004 samples are obtained and test data are statistically arranged.Then,the relations between the static vision and dynamic vision of testees and their age,driving age,driving length of time and the weather are analyzed and studied.It shows that the average value of static and dynamic vision of drivers on the desert highway is respectively 1.3 and 0.7.Comparing with the static vision,the dynamic vision in desert highway reduces 44.75%,which is far higher than that in oasis area.Correlation analysis also shows that drivers' age,driving age,driving length of time and air temperature has great effects on the reduction of their static vision and dynamic vision,and the degree of correlation is all above 0.76.
