摘要: 为量化走行高度对疏散人员运动特征的影响,应用虚拟现实(VR)技术构建高度不同的疏散试验场景,采用激光测距雷达记录被试走行试验数据,利用恐高症评定问卷(AQ)与K均值聚类算法划分恐高等级,探究控制高度条件下不同恐高程度与性别对疏散人员速度、步幅与步频的影响。结果表明:随着试验场景高度增加,行人的疏散速度、步幅与步频下降,0~50 m高度范围内下降明显;相同高度下,恐高程度越大,行人速度与步幅越小,步频越快,对高度变化越敏感;女性步行速度与步幅下降幅度大于男性,相同高度下,男性步行速度与步幅大于女性。

Abstract: In order to quantify influence of walking height on motion features of evacuees, VR technology was adopted to construct evacuation scenarios of different heights. Then, experiment data were collected with laser radar, and fear of height was classified by using acrophobia questionnaire (AQ) and K-means clustering algorithm. Finally, influence of different levels of acrophobia and gender on evacuees' speed, stride and step frequency were investigated at controlled height. The results show that evacuation speed, stride and step frequency of pedestrians decrease along with the increase of height, which is more obvious as it is between 0 m and 50 m. When at the same height, those whose acrophobia is more severe will have lower speed, smaller stride, faster step frequency and are more sensitive to height changes. It is also found that female's walking speed and stride decrease more observably than those of males while the latter's walking speed and stride are larger than females at the same height.

Key words: virtual reality (VR) technology, working height, cvacuation, degree of acrophobia, motion features
