近年来，人群模拟受到了广泛的关注。研究人群流动的原因之一是为了在不可预测的事件发生时优化密集建筑物和城市中心的疏散程序。这种疏散计划可以在海啸等突发灾难性事件中挽救许多生命。在本文中，分阶段疏散策略的有效性进行了检查，在一个大型展览馆设施，假设完全和部分遵守疏散指示的疏散人员。数值分析表明，与传统的同时疏散相比，分阶段疏散对缓解高密度人流和严重拥挤状态有积极作用。我们的方法有可能对调查在复杂的城市空间减少灾害风险的战略作出贡献。
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.
