Abstract

Emergency fire situations in tunnels can be especially dangerous when occurring in long underground or subsea tunnels, particularly when evacuation on foot is the only alternative. This paper presents the results from a study comparing different visual and acoustic measures to facilitate efficient and safe emergency evacuation and their effect on people's self-rescue behaviour in response to a tunnel fire. Eighty-one participants evaluated seven different scenarios in virtual reality with or without visual and acoustic supporting measures (i.e. signs, lights, acoustic beacons) to find their way to emergency doors. Objective behavioural data, such as orientation, and walking speed, were collected. The results suggest that the distance between the emergency doors increases uncertainty and affects the time to self-rescue significantly, with four times longer times for 500 m than 250 m between doors. Additionally, the use of continuous guiding lights positively supported orientation and walking speed, with 97 % of the participants finding their way and showing a reduction of time to reach the emergency door of 10–20 s. The study underscores the importance in the proper visual and acoustic evacuation measures for the wayfinding of emergency exits, improving self-rescue of people.

利用虚拟现实技术分析公路隧道自救的视觉和声学措施
隧道中的紧急火灾情况如果发生在较长的地下或海底隧道中,尤其是当徒步疏散是唯一的选择时,就会特别危险。本文介绍了一项研究的结果,该研究比较了促进高效安全紧急疏散的不同视觉和声学措施及其对人们在应对隧道火灾时的自救行为的影响。81 名参与者在虚拟现实中评估了七种不同的场景,在有或没有视觉和声学辅助措施(即标志、灯光、声学信标)的情况下,他们都能找到通往应急门的道路。研究收集了客观行为数据,如方向和行走速度。结果表明,紧急救援门之间的距离增加了不确定性,对自救时间的影响很大,门与门之间 500 米的距离要比 250 米的距离长四倍。此外,使用连续的引导灯对定向和步行速度有积极的帮助,97% 的参与者都能找到自己的方向,到达紧急出口的时间也缩短了 10-20 秒。这项研究强调了适当的视觉和声学疏散措施对寻找紧急出口、提高人员自救能力的重要性。

期刊介绍: Fire Safety Journal is the leading publication dealing with all aspects of fire safety engineering. Its scope is purposefully wide, as it is deemed important to encourage papers from all sources within this multidisciplinary subject, thus providing a forum for its further development as a distinct engineering discipline. This is an essential step towards gaining a status equal to that enjoyed by the other engineering disciplines.
