| 摘要： | Simulated emergency evacuations were conducted from a narrow-body transport airplane simulator through a Type-Ill overwing exit. The independent variables were passageway configuration, hatch disposal location, subject group size, and subject group motivation level. Additional variables of interest included individual subject characteristics, i.e., gender, age, waist size, and height, all of which had been shown in previous studies to significantly affect emergency egress. Participants were restricted to those who had no previous emergency evacuation (research) history. The dependent variables of interest included hatch operation time and the time for individual subjects to egress. Evacuation trials were conducted with 48 groups of either 30, 50, or 70 subjects per group, for a total of 2,544 subject participants. Each subject group completed 4 evacuation trials, totaling 192 evacuations. Results reported for hatch operation time include data from all trials, since each trial had a different, naive hatch operator. The egress time results include data only from each group's first evacuation trial in which every subject was naive. Significant main effects of hatch disposal location on both Exit-Ready-To-Use Time (p<.004) and First-Person- Out Time (p<.008) were revealed, without effects of the other variables. Significant main effects on individual subject egress time were found for waist size (p<.OOOl), gender (p<.OOOl), and age (p<.OOOl). A small, but significant, main effect was also found for passageway configuration (p<.OOl), which was confounded by improper hatch disposal and a between-groups imbalance in individual subject characteristics. This situation produced a significant (4-way) passageway configuration by hatch disposal location by subject group density by subject group motivation level interaction effect (p<.OO8). |
