In recent years, crowd simulation has received a surge in attention. One of the reasons for investigating crowd flow is to optimize evacuation procedures from densely occupied buildings and urban centers in case of an unpredicted event. Such evacuation planning can save many lives at sudden catastrophic events like tsunami. In this paper, the effectiveness of phased evacuation strategies is examined in a large-scale exhibition hall facility, under the assumption of both full and partial compliance of evacuees with the evacuation instructions. It is clearly demonstrated by numerical analyses that phased evacuation has positive effects on the mitigation of high-density pedestrian flows and heavily congested state in comparison with traditional simultaneous evacuation. Our approach has potential for contribution toward investigating disaster risk reduction strategies in complex urban space.
