Abstract

The underground mall of Central Park located in Nagoya is in a low risk of river and urban floodings. This paper reports potential locations of crowd congestion in case of fire or earthquakes via simulation and proposes evacuation instructions for visitors. The presented study differs from other works in two aspects. First, it is a simulation based on real number of visitors to the mall counted in our field activities. Second, it is a 3D simulation utilizing the 3D model created by referencing the record drawings of the mall. It is found that crowd congestion occurs in 4 stairs connected to the ground amaong these 28 stairs without providing proper instructions to visitors. In contrast, if the evacuation instuructions we propse are provided, our simulation results show that crowd congestion can never happen and every visitor can escape from the mall to the ground within 3 minutes.
