Abstract

As a city is grown, its population would be incredibly bigger. Due to the population growth, city's functional or residental building and even transports are suggested to occupy underground space. Underground stations in Daegu could be divided into four spheres depending on usage purpose of local area. In this study, the number of users in each sphere was analysed by vertical distribution which meant each floor of underground station and also the number of users of each underground station is analysed according to a time period. Egress simulation modelling were performed after setting up the number of users based on field-measurement from examination. From a result of evacuation simulation, occupants' evacuation behaviours and deviations were concretely considered. To be conclusion, this study can be a guideline or suggestion for improving design and performance of evacuation safety in underground stations.
