【摘要】：在分析、比较现有疏散仿真模型的基础上,提出一种基于正六边形元胞自动机的行人疏散模型。该模型中疏散空间被分成相等的正六边形,每个行人有包括静止在内的7个运动方向。给出速度等级的概念用来描述行人的疏散速度。在疏散过程中行人选择出口的决策由到出口的距离、视野内行人数量和密度决定。为展示恐慌心理对疏散过程的影响,定义了恐慌系数。通过实验仿真了有恐慌和无恐慌2种情景下的疏散过程,结果表明,该模型可真实地反映实际的疏散过程,可为真实的行人疏散和评估公共建筑设计起到一定的参考作用。
[Abstract]:Based on the analysis and comparison of the existing evacuation simulation models, a pedestrian evacuation model based on hexagonal cellular automata is proposed. In this model, the evacuation space is divided into equal hexagonal, and each pedestrian has 7 moving directions including static. The concept of speed class is given to describe the evacuation speed of pedestrians. In the process of evacuation, the decision to choose exit is determined by the distance from exit to exit, the number and density of pedestrians in the field of vision. In order to show the effect of panic psychology on evacuation process, the panic coefficient was defined. The evacuation process with panic and without panic is simulated experimentally. The results show that the model can truly reflect the actual evacuation process and can play a certain reference role in the real pedestrian evacuation and the evaluation of public building design.
