Abstract

The purpose of this study is to reveal the effects of the number of users and their spatial distribution on the evacuation time in a road tunnel in the event of a fire. An agent-based evacuation model was implemented using Netlogo following the ODD protocol. The proposed model illustrates how the evacuation behavior of one can hinder others across different evacuation environments. Simulations show that evacuation time increases with the number of users when they are randomly located in a road tunnel.

최근 들어 도로의 선형 개량 및 설계속도 향상으로 인해 장대터널에 대한 수요가 증가함에 따라 대피 시간의 지연과 같은 이용자 취약성이 더욱 높아지고 있다. 향후 도로터널의 장대화 경향은 심화될 전망이므로 화재에 대한 이용자 취약성을 검토하고 효율적 대피 방안을 세우지 못한다면 더 큰 인명 피해가 발생할 수 있을 것이다. 이에 본 연구는 적정시간 안에 이용자들이 대피해야 사상자 발생이 최소화 될 수 있다는 점을 고려해 다양한 상황 조건 아래 대피 시간을 산정하는 연구를 수행하였다. 개발된 모형에서 행위자는 이용자이며, 이들은 퇴피성, 직진성, 좌향성 등의 행위 규칙에 따라 대피를 진행하도록 모형을 설계하였다. 개발된 모형은 ODD 규약에 따라 설명하였고 시뮬레이션을 위해 NetLogo 5.2를 활용해 구현하였다. 이 모형과 두 가지 시나리오를 활용해 현행 피난연결통로 설치지침을 평가하였다. 그 결과 터널 내부의 차량이 정체 수준일 경우 현행 지침은 다소 미흡한 것으로 판명되었다.
