基于正六邊形元胞自動(dòng)機(jī)的行人疏散研究
[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.
