摘要
基于疏散动态学的理论,归纳研究中美两国在地铁设计中有关客流安全疏散方面的国家规范后,开发了计算机模拟仿真客流疏散系统的部分功能,使用OGRE设计并实现了系统的客流疏散效果展示模块.用户通过使用此模块,可以方便地观察到目前已经搭建的地铁站客流疏散模型的直观效果.此模块运用颜色渐变过渡的方式展现了真实客流疏散的区域密集程度.设计并实现了客流疏散系统全方位空间坐标系模块与客流疏散系统子场景坐标转换机制,让用户在使用本系统搭建场景时更加人性化,并在模块接合方面对模块化合作完成客流疏散系统提供很大的便利.
Based on the evacuation dynamics, Chinese and America national specifications in subway design about traffic safety evacuation were inductively researched. Then a computer simulation of passenger evacuation system was developed, which used the OGRE engine to design and implement the module to show the evacuation effect. By using a module that shows the evacuation effect, users could observe the evacuation effect of the finished subway station model. This module uses the method of color gradient to show the intensity of the passenger evacuation area, is good at designing and implementing the omni-directional space coordinate system module and the sub-scene coordinate transformation mechanism module of passenger evacuation system. These modules can help build a more humanized system and are quite crucial to modular collaboration in passenger evacuation.
