一种通用的层次化人群疏散仿真框架

为建立一个具备高扩展性的人群疏散仿真可视化统一平台,对不同人群疏散模型进行动态环境下的人群仿真,探讨了人群仿真系统的拓展性问题。通过分析并改进现有仿真框架Menge,在其基础上设计了环境层、战略层、战术层、操作层和可视化层相结合的层次结构,并在各层次设计了拓展接口,以用户自定义的形式添加不同模块来实现各层次具体功能拓展。该仿真框架可以有效支持用户设计并实现各种人群疏散仿真实验,对比较不同人群疏散仿真模型的差异具有重要作用。

A Common and Hierarchical Crowd Evacuation Simulation Framework

In order to establish a highly scalable platform for crowd evacuation simulation visualization, simulate the crowds in different environments on different population evacuation models, the expansion of crowd simulation systems are explored. By analyzing and improving the existing simulation framework Menge, the level architecture of environment level, strategy level, tactical level, operation level and visualization level are designed, and the expansion interfaces are designed at each level. In user-defined form, the different modules can be added to each level to achieve specific functions. The simulation framework can effectively support users to design and implement various crowd evacuation simulation experiments, and plays an important role in comparing the differences of different population evacuation models.
