摘要
为探讨高原公路线形对驾驶员心理和生理特性的影响,利用生物反馈系统对急进高原公路的驾驶员进行实地行车试验。通过定量分析,分别建立驾驶员β频段脑电(EEG)信号变化值与试验路段海拔、道路线形之间的关系模型。分析结果表明:高原公路驾驶员行车时的β频段脑电信号变化值随路段海拔的升高而增大,它与道路平曲线半径成负相关;纵坡度的变化对β频段脑电信号变化值的影响不显著,线形组合值的增加会导致脑电波频段功率值上升;海拔和线形组合值同时作用时,驾驶员的脑电波频段功率值变化更加显著。
For the sake of exploring influence of plateau highway line-type on psychological and physiological reactions of drivers,driving experiments were carried out using a biofeedback instrument. On the basis of both the experimental results and theoretical analysis,a model was built for the relationship between the driver＇s beta band power value of EEG,plateau highway alignment and altitude on highway. The analysis results show that the driver＇s beta band power value will go up with the increase in altitude,that the correlation between beta wave and horizontal curve is negative,that longitudinal slope has no significant effect on the beta wave,that an increase in alignment combination will lead to an increase of driver＇s beta band power value,and that the driver＇s beta band power value will increase more significantly when both the altitude and alignment combination increase.
