This study analyzes the Required Safe Egress Time (RSET), in the event of a fire at a welfare center for the disabled, using the emergency passage according to the floor arrangement of users to evaluate the safety and the difference in RSET for each emergency passage using the Pathfinder simulation program to suggest an efficient evacuation method. As a result of RSET, it was found that there is no problem in evacuation safety for the current state of the facility's personnel allocation by satisfying the standard RSET in case of fire, and evacuation can be completed safely by evacuating through stairs rather than using elevators if possible. It is necessary for employees to be provided sufficient education and training in advance so that they can evacuate effectively with the disabled in case of fire. This study gives significance in saving many precious lives and safely evacuate in case of fire as evacuation routes were secured through the design, construction and operation of facilities for the disabled and the RSET was shortened through regular evacuation practices. It is necessary to discuss the further RSET studies based on the automatic fire shutters open or not when a fire occurs at a specific location following the installation of automatic fire shutter at the entrance of each floor of the facilities.

A subway system is one of the major transportation modes at a metropolitan area. When it meets the other lines, the metro station, so-called transferring station, is usually threatened by severe pedestrian congestion and safety issue of transit users including the transportation vulnerable. Although transportation planners forecast travel demand at the beginning, it is not easy to predict pedestrian flows precisely for a long term if land use plans have dramatically changed. Due to expensive costs, structural extension of metro stations is limited. Therefore, it requires efficient and technical improvements as meeting the demand of pedestrian and physical characteristics. In this study, the core mechanism of pedestrian movement-based simulation model was introduced and evacuation scenarios were analyzed with the developed model. As a result, the multiple optimal routes for unexpected events at the solid space of the multiple stories are easily searched through the simulator and in the case of Sadang Station, travel time can be reduced by 60% when the evacuation information and intuitive design are provided.

Users of passenger ships and cruise ships are rapidly increasing year by year, and the needs of the floating architecture are newly come out. But the studies about the passengers' safety and the countermeasures against incidents on board the ships are rare, although the ships' incidents are occurred averagely 15 cases per year during last 10 years. For the purposes of the analysis of the safety consciousness and gathering the some of input data for evacuation simulation for Korean passengers on board ships, this study performed surveys targeting ordinary 394 passengers who are not specially trained and/or accustomed with onboard living conditions. The results are the followings. The reliability on ships' safety is surveyed as 32.3%. Only 14.6% of respondents are aware that there were safety education on board ship during sailing. And 42.2% and 40.9% of respondents answered that they saw the map of emergency routes and knew where the life boats are, respectively. And 73.3% select crews' direct or in-direct(like announcement by indoor broadcasting system) guidances as the most effective evacuation method.
