초록

여객선을 이용하는 대부분의 일반 승객들은 승선환경 비숙련자이기 때문에, 재난환경에서 일반승객의 행동특성을 파악하고 이를 재난대응방안수립에 반영하는 것은 매우 중요한 일이다. 이 연구는 재난상황 중 발생 가능성이 매우 높은 정전조건에서 선내환경 비숙련자들의 이동특성을 파악한 것이다. 연구성과를 정리하면 다음과 같다. 정상조명조건에 비해 정전조건일 때의 이동시간이 전구간에서는 155.8~247.1 %, 복도 구간에서는 56.9~331.7 %, 계단 구간에서는 75.3~152.9 % 각각 더 소요되는 것으로 측정되었다. 정전조건 시나리오 중에서도 피난유도기구가 설치된 경우가 그렇지 않은 경우에 비해 이동시간이 전구간에서는 21.6~24.0 %, 복도구간에서는 37.7~58.9 %, 계단구간에서는 18.7~19.2 % 각각 짧았다. 피난유도기구가 없는 정전조건에서 이동에 도움을 준 것이 무엇인가라는 설문에 대해 유효응답자의 60.7 %가 벽/계단(35.7 %), 핸드레일(25 %) 등 선내 구조물을 선택하였고, 28.6 %는 개인적 직감에 따라 이동하였다고 응답하였다. 그러나 피난유도기구가 부착된 실험에 참여한 후 동일한 설문에 대해서는 유효답변의 50 %가 피난유도기구를 선택하였다.

Because most of the passengers are not accustomed with onboard environments, it is very important to analyze and predict the behaviors' characteristics of passengers under disasters' conditions, and apply those results for making countermeasures. On this view point, this study focused on the walking characteristics of onboard-novices are tested and analyzed under blackout condition that has high possibility to happen. As a result, comparing to under normal lighting conditions, the waking times under blackout conditions are 155.8~247.1 % longer on full path, 56.9~331.7 % on corridors, 75.3~152.9 % on stairs, respectively. And under the same blackout conditions, walking times in cases of the exit guidance marks being attached on top side of walls saved times, like 21.6~24.0 % on full path, 37.7~58.9 % on corridors, 18.7~19.2 % on stairs, comparing to the cases of exit guidance marks being not attached. On the other hand, after tests under without exit guidance marks, 60.7% among respondents answered that internal structures like wall/stair (35.7 %) and handrail (25 %) are very helpful to decide way findings, and 28.6 % selected personal instincts is important. But 50 % responded that exit guide marks are effective to find ways, after the tests under with exit guidance marks.
