Research On Driver’s Physiological Characteristics In Plateau Highway Based On Biological Feedback Test

Roads in Plateau areas has the following features:low oxygen containing, monotonous road landscape, complex road linear and dangerous. People will inhaled less oxygen and scaled with earlier hypoxemia in plateau, which will caused the change of psychological and physiological of. drivers and then caused safety problems through affecting the operation ability of drivers.This paper expounded the change of physiological indexes along with the change of altitude-s continuous driving time and running speed in plateau areas through the experiment on G314 from Kashi to Hongqilafu.By using partial correlation analysis, we analyzed the physiological indexes and impact factors in plateau areas.The analysis shows that the running speed has no impact on drivers’ physiological indexes.By using correlation analysis with SPSS, we analyzed the correlation between all the indexes with altitude and continuous driving time.The analysis shows the Following.During all the indexes, Heart Rate and EEG have the highest correlation with altitude and continuous driving time. We decided to analyse the trend of heart rate and eeg with the change of altitude and continuous driving time.The correlation of electromyography、standards and calibration Laboratory、blood volume amplitude and motility is less than 0.3.According to this,we didn’t make the following analysis of these four indexes.During heart rate related indexes, Values of SDNN、LF、 LF/HF showed a certain degree of increase and HF showed a certain trend of decreases, what proved all the samples were fatigued. Along with the altitude and continuous driving time increase, all the indexes of electroencephalogram showed a certain trend of increase When samples driven up.This proved that samples were fatigued. Along with the altitude decrease and continuous driving time increase, theta and delta of electroencephalogram showed a certain degree of increase When samples driven down.But the increment speed when driven down is slow than those when driven up.This proved that rhe samples were fatigued but the increment speed when driven down is slowly than those when driven up, which shows that the increase of altitude can get drivers fatigued.
