摘要
山区双车道公路有丰富的行车路域空间,为研究不同路域空间类型中驾驶人的心生理负荷,进行了实车试验,采集了被试的瞳孔面积变化率和心率变化率,作为驾驶视觉心生理负荷的表征指标.结果表明:在开敞式空间中,驾驶人的视觉心生理负荷最小,半郁闭式的较大,郁闭式的最大.研究结果揭示了山区双车道公路不同路域空间下驾驶人视觉心生理负荷的变化特性.
There were plenty of highway landscapes in mountainous two-lane highway.In order to study the driver’s psychophysiological load in various highway landscape types,a real vehicle test was carried out.The pupil area change rate and heart rate change rate of the subjects were collected as the characterization index.The results show that in the open landscape,the drivers’visual psychophysiological load was the smallest,the semi-closed landscape was larger,and the closed landscape was the largest.The results reveal the variation characteristics of drivers’visual psychophysiological load of various highway landscape in mountainous two-lane highway.
