Evacuation Simulation Analysis Based on Continuum Model

The continuum model for pedestrian flow intuitively reflects the evacuation features of the crowd evacuation process. In this paper, the authors used the continuum model for pedestrian flow to study the evacuation feature of pedestrians in the typical evacuation scenario. The continuum model for pedestrian flow and its equations were established using COMSOL. The continuum model and its iterative calculation framework were implemented by developing code in MATLAB. The Eikonal equation was solved by the fast sweeping method to obtain the potential function. In each iteration loop, the potential function was imported as the initial variable, and the calculation module of COMSOL was called to solve the transient control equation of the model. The typical self-organization phenomena of pedestrian flow were reproduced in two standard examples, and the rationality of the continuum model was verified. The results showed that the model of evacuation simulation and the calculation program were reliable. The evacuation simulation analysis can provide technical support for the development of personnel evacuation schemes, function design and safety layout for practical engineerings.
