Abstract

To increase the safety of onboard evacuation of guests who is unfamiliar with onboard living conditions, this study measured and compared the onboard walking speeds of 81 participants on a passenger ship, I t were found that the walking speeds at corridor on navigation were slower than those at berth by 27.2%, and the speeds of walking on the corner on navigation were slower than those at berth by 23.2%. This means that the ship motion on navigation directly influenced walking speeds. The walking speeds of upward-stairs and downward-stairs were measured to be 0.71m/s and 0.75m/s, respectively. From the crowd counter-flow experiments, because of the narrow space between participants, the walking speeds were decreased as person after person. And it was clear that the group's walking speeds were determined by the walking speeds of leading person(s) of the group. The walking speeds obtained this study were different from those of IMO guideline(MSC/Circ 1033).

본 연구는 승선 생활에 미숙련된 일반승객이 해상재난 발생 시 여객선 내에서의 안전성을 확보하고 피난성능을 향상시키기 위한 기술 개발에 반드시 필요한 선박 항해 환경에 따른 승선 중 보행속도를 실측실험을 통해 취득하고 이를 비교 분석한 것이다. 81명의 남녀 대학신입생이 참가한 승선 실험에서, 평면복도 직선부에서의 평균보행속도는 항해시가 정박시보다 27.2%, 평면복도 코너부에서는 23.2% 느려지는 것으로 나타나 항해중 선박 동요에 따른 속도 저하가 크다는 사실을 알 수 있다. 항해상태에서 실측된 상향계단과 하향계단에서의 평균보행속도는 각각 0.71m/s, 0.75m/s으로 측정되었다. 군집충돌 이동실험에서는 인근 보행자와의 보행 간섭으로 인해 후미로 갈수록 보행속도가 느려지고, 선두의 이동속도가 군집 전체의 이동속도에 큰 영향을 준다는 사실을 확인하였다.
