驾驶员安全可靠性多因素分析

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。

Multi-factor Analysis of Driver Safety Reliability

Many factors affect the reliability of driver safety; this paper analyzes 22 indices in six major elements.Reaction ability uses five correlative variables to measure driver response to stimuli.Balance control,with four variables,reflects the ability of the central nerve system to control balance.Visual ability uses five variables to describe the visual capabilities of drivers.Attention ability has four variables,which describe the attention of drivers.Speed judgment uses three variables to assess the ability of drivers to judge speeds.Aural ability describes the aural capability of drivers.Based on the integration of all the major elements,the paper builds an evaluation index of driver safety reliability..
