In this study, the subjective feelings from questionnaires, the physiological signals-based emotions, and walking speed were investigated by a full-scale smoke-filled tunnel experiment. The physiological signals-based emotions were compared by the subjective feelings. The present mean speed was slower than the results of previous studies regarding evacuation in smoke, and close to the completely darkened walking speed, even the participants who were familiar with tunnels. The negative emotion degree via physiological signals, which was determined by the heart rate change rate, was anxiety > fear up to = 1.0 m and then switched to fear > anxiety over 1.0 m. It could be considered that the fear might be large with smoke density due to their present threat (not future threat). The tendency of the mean walking speed by negative emotion via physiological signals was the same as the negative emotion degree in smoke.

浓烟隧道疏散负性情绪程度


在这项研究中，通过全面的烟雾弥漫的隧道实验来调查问卷的主观感受、基于生理信号的情绪和步行速度。基于生理信号的情绪通过主观感受进行比较。目前的平均速度比之前关于烟雾中疏散的研究结果要慢，并且接近完全黑暗的步行速度，即使是熟悉隧道的参与者也是如此。通过心率变化率确定的生理信号的负面情绪程度，在 = 1.0 m 之前为焦虑 > 恐惧，然后在超过 1.0 m 时切换为恐惧 > 焦虑。可以认为，由于他们当前的威胁（而不是未来的威胁），烟雾密度可能很大，恐惧可能很大。生理信号产生的负面情绪对平均步行速度的趋势与烟雾中的负面情绪程度相同。
