摘要
基于正方形网格元胞自动机模型,开发了三维疏散仿真平台CDS。该软件通过读取AutoCAD图纸建立建筑模型并提供简便的楼梯建模方法。软件考虑了人员密度和疏散距离对人员行走速度的影响;通过设置不同的出口类型,考虑人员对建筑的熟悉程度及出口选择策略。模型验证表明,CDS平台计算精度高,能满足疏散仿真的工程需求。
Based on cellular automata model of square grid, a 3D evacuation simulation platform CDS was developed. Building models are built by using the AutoCAD drawings and the soft- ware provide easy modeling of stairs. CDS considers personnel density and evacuation distance effect on human walking speed. The familiarity of the construction and exit selection strategy are considered by setting different exit types. The model verifi- cations showed that the CDS platform with high precision can meet the requirements of evacuation simulation.
