摘要
在二维元胞自动机的基础上提出2.5维元胞自动机的新概念。以大型运动场馆为研究对象,研究和建立了基于2.5维元胞自动机的人群疏散网格模型。该模型兼顾考虑了场地客观因素及人员主观因素方面的影响,引入的高程因素对人群疏散情况分析是有效的。最后通过实例论证了提出的2.5维元胞自动机模型对人群疏散仿真效果的实用性及合理性。
Based on 2-dimensional cellular automaton （CA）, the new conception of 2.5-dimensional CA is presented. Taking large sport stadium as research object, a grid-based model for crowd evacuation based on 2.5D CA is established. The model thinks over both the objective factors from scene of venue and subjective factors from evacuees＇ sensation, and introduction of altitude factor is effective for analyzing the evacuation of urgent situation. In the end, the tested example proves that the 2.5D-CA-model is practicable and reasonable for crowd evacuating emulation.
