影响驾驶员安全可靠性的身心因素很多,研究中对22项指标进行分析,将有关指标合并,归纳为6种主因子:第一主因子相关变量5种,反映驾驶员的反应能力;第二主因子相关变量4种,反映中枢神经系统的平衡控制能力;第三主因子相关变量5种,反映驾驶员视觉功能;第四主因子相关变量4种,反映注意综合品质;第五主因子相关变量3种,反映驾驶员速度判断能力;第六主因子为驾驶员听觉能力。基于主因子分析进一步整合,建立驾驶员安全可靠性评价指标体系。
There are many physical and psychological factors that affect the driver’s safety and reliability. In the study, 22 indicators were analyzed, and the relevant indicators were merged and summarized into six main factors: five variables related to the first principal factor, reflecting the driver’s responsiveness; the second Four main variables related variables, reflecting the central nervous system balance control ability; the third major factor related variables 5, reflecting the driver’s visual function; the fourth major factor related variables 4, reflecting the attention to overall quality; the fifth major factor related 3 variables, reflecting the driver’s ability to judge speed; the sixth main factor for the driver’s hearing ability. Based on the further analysis of the main factor analysis, the driver safety and reliability evaluation index system was established.
