Abstract

The use of raised walkways in rail tunnels has the potential to significantly improve evacuation conditions, however there is limited research that has so far focused on walkway design from an evacuation perspective. An experiment was therefore performed to explore the effect of walkway design, namely walkway width and evacuation aids, on evacuation behaviour, e.g., people’s perception, movement speeds and flow rate. The results indicate that a walkway width of more than approximately one metre (0.9 to 1.05 m) leads to higher movement speeds and increased sense of safety. Handrails and a tactile edge marker are often appreciated evacuation aids as they are perceived as facilitating and safety-enhancing features. Based on the results, a correlation between flow rate and walkway width has been developed. This correlation and the collected data may potentially be used in future cost-benefit analyses to shed light on the most appropriate walkway design for specific tunnels.

铁路隧道架空人行通道设计对疏散行为的影响
在铁路隧道中使用高架人行道有可能显著改善疏散条件,然而,迄今为止,从疏散角度关注人行道设计的研究有限。因此,我们进行了一项实验来探索人行道设计,即人行道宽度和疏散辅助设备,对疏散行为的影响,如人们的感知、移动速度和流量。结果表明,人行道宽度超过约一米(0.9至1.05米)会导致更高的移动速度和增强的安全感。扶手和触觉边缘标记通常被认为是疏散辅助工具,因为它们被认为是方便和增强安全的特征。在此基础上,建立了流量与通道宽度的关系。这种相关性和收集的数据可能会在未来的成本效益分析中使用,从而为特定隧道提供最合适的人行道设计。
