Abstract This study proposes user density [m2/person]requiredforperformance-based fire protection design of traditional markets by market size according to floating population through business district analysis. Furthermore, the floor plans and internal layouts of building-type traditional markets are analyzed and categorized into four floor plans and three internal layouts. The simulation input values are derived according to the floor plan and internal layout types, and fire and evacuation simulations are performed. The simulation results show that evacuation safety of the building-type traditional markets cannot be achieved because the required safe egress time (RSET) exceeds the available safe egress time (ASET). Thus, alternative solutions are presented by the size of traditional market. The evacuation safety can be secured by installing fire shutters and increasing the corridor width near the stairs for small and medium markets. For medium-large and large markets consisting of 3-story or high buildings, the evacuation safety can be secured by increasing the external stairs and corridor width. Thus, the standards for corridor width and fire shutters for preventing bottleneck phenomenon near the stairs by market size must be strengthened to secure the safety of users in the event of fires.
