A Study on Selecting the Best Location of ‘Shelter In Place’ in Light Rail Station using Egress Simulation and BIM Model

As the only divided country, preparing for possible risks is to be considered in Korea. In these circumstances, rather than just increasing the number of evacuation facilities, it is needed to establish and manage SIP, the space that is used for its original purpose in normal situation but can be utilized as a shelter during CBRE situation. Therefore, in this study, light rail station is modeled by using BIM software and the process of selecting the best location of SIP in the station by performing several simulations accordance with various escape scenarios was presented. Since the process proposed in this study is based on rational analyses of human behavior through direct simulations, if applied to various infrastructures, it is expected for people to evacuate fast and safely under CBRE situation.
