Abstract This study presents an evacuation experiment to test individual behavior in an interactive virtual environment. A total of 68 test scenarios were established, and 122 participants were recruited to take part in all the test scenarios. The results show that individual attributes, such as sex, education background, age, and evacuation experience, have a correlation with the participants’ ability of escaping in the virtual evacuation environment. Specifically, younger men with higher education level and evacuation experience may have a better ability of escaping. The comparison of the evacuation paths, directions, and times among 8 scenarios with different sets reveals that people prefer to select the shortest route, but keep away from the fire source as much as possible if a fire happens. On the other hand, other people compete with the individual for the available evacuation resources, but when the exit location is unknown, other people may help individuals find the exit. In addition, the visibility decreases in case of fire, which is the most difficult condition for escaping with the longest movement distance and most evacuation time. This study will be useful to understand the human behavior and movement characteristics during evacuation by using a cheap and safe method.

虚拟环境下紧急疏散过程中的人体运动特征

摘要 本研究提出了一个疏散实验,以测试交互式虚拟环境中的个人行为。总共建立了68个测试场景,并招募了122名参与者参与所有测试场景。结果表明,性别、教育背景、年龄、疏散经历等个体属性与参与者在虚拟疏散环境中的逃生能力存在相关性。具体而言,受教育程度较高、有疏散经验的年轻男性可能具有更好的逃生能力。8种不同场景的疏散路径、方向和时间的比较表明,人们更喜欢选择最短的路线,但在发生火灾时尽可能远离火源。另一方面,其他人与个人争夺可用的疏散资源,但当出口位置未知时,其他人可能会帮助个人找到出口。此外,发生火灾时能见度下降,是最难逃生的条件,移动距离最长,疏散时间最长。这项研究将有助于通过使用一种廉价且安全的方法了解疏散过程中的人类行为和运动特征。
