Abstract

This paper introduces 'EgresSIM', which is microscopic evacuation simulation software. EgresSIM developed in this paper is a three-dimensional (3D) pedestrian evacuation simulator based on the improved model advanced from the floor field model(FFM), a microscopic pedestrian model. This software can simulate large size buildings that consist of a number of floors, stairs, rooms, and exit doors. Moreover, this software can arrange several hundreds or thousands of pedestrians in indoor space and check their movements through the 3D viewer in real time, as well as produce detailed results about evacuation situations such as which paths are employed by individual pedestrians, how long does it takes to evacuate, and how many evacuees are gathered at each of the exit doors. Building data needed in the simulation are constructed as XML files according to pre-defined indoor data models and information of simulation results is also created as XML log files. A moving pattern of pedestrians can be represented in many ways by adjusting the sensitivity parameters of two walk models supported by EgresSIM. Thus, evacuation simulation can be done based on many assumptions of situations such as movement to the nearest exit door or blackout after outage.

본 논문은 미시적 대피시뮬레이션 소프트웨어인 'EgresSIM'을 소개한다. 본 논문에서 개발한 EgresSIM은 미시적 보행모델인 Floor Field Model과 이를 발전시킨 개선된 모델을 기반으로 하는 3차원 보행자 대피시뮬레이터이다. 이 소프트웨어는 많은 층과 계단, 방, 출입구 등이 있는 대형건축물에 대한 시뮬레이션이 가능하다. 또한, 수백, 수천 명의 보행자를 실내 공간에 배치하고 이들의 움직임을 3차원 뷰어를 통해 실시간으로 확인할 수 있고, 개별 보행자들이 어떤 경로로 이동하는지, 대피시간은 얼마나 소요되는지, 각각의 출구에 얼마나 많은 대피자들이 몰렸는지 등 대피 상황에 대한 상세한 결과를 산출한다. 시뮬레이션에 필요한 건물 데이터는 사전에 정의된 실내 데이터 모델에 따라 XML 파일로 구축되며, 시뮬레이션 결과 정보도 XML 로그파일로 생성된다. EgresSIM에서 지원하는 두 가지 보행모델의 민감도 파라미터를 조정함으로써 보행자들의 이동 패턴을 여러 가지로 나타낼 수 있다. 이를 통해 최단 거리 출구로 이동하는 상황, 정전이 일어난 암흑 상황 등 여러 상황을 가정한 대피시뮬레이션 수행이 가능하다.
