Abstract

This study investigates the impact of inclined conditions on pedestrian walking speeds, focusing on both individual and crowd walking modes. A total of fifteen different combinations of heeling and trim angles were simulated to conduct a comprehensive evacuation experiment. The heeling angles

α

considered were

0^{\circ}

5^{\circ}

, and

10^{\circ}

, while the trim angles

β

were

0^{\circ}

\pm 10^{\circ}

, and

\pm 15^{\circ}

. Results indicate that average pedestrian walking speeds in both individual and crowd walking modes follow a similar trend as the trim angle

β

varies from

- 15^{\circ}

15^{\circ}

, with the heeling angle

α

0^{\circ}

5^{\circ}

, or

10^{\circ}

. Under combined trim and heeling conditions, the average pedestrian speed in crowd walking mode is more sensitive to changes in heeling inclination compared to individual walking mode. Furthermore, under the same inclination angles, pedestrian walking speeds in crowd walking mode exhibit a more concentrated distribution compared to those in individual walking mode. Moreover, analysis of the spatiotemporal distribution of instantaneous velocities reveals that the trends in walking speeds during crowd walking mode in inclined scenarios follow a similar pattern to those observed in individual walking mode. The results will provide fundamental guidance to the practical human evacuation from passenger ships.

考虑倾斜和倾斜联合效应的行人行走速度实验研究

本文研究了倾斜条件对行人步行速度的影响，重点研究了个体步行和人群步行两种方式。模拟了15种不同的倾侧角和纵倾角组合，进行了综合疏散实验。考虑的倾斜角α为0、5和10°，而倾斜角β为0、±10和±15°。结果表明，个人步行和人群步行两种方式下的行人平均步行速度随倾斜角β在- 15 ~ 15°以及倾斜角α在0、5、10°的变化趋势相似。在纵倾和倾侧联合条件下，人群步行模式下的平均行人速度比个体步行模式对倾侧倾角的变化更为敏感。在相同的倾斜角度下，人群步行模式下的步行速度比个体步行模式下的步行速度分布更为集中。此外，对瞬时速度的时空分布分析表明，倾斜场景下人群步行模式下的步行速度趋势与个体步行模式下的步行速度趋势相似。研究结果将为客船人员疏散的实际操作提供基础指导。
