Cellular Model of Room Evacuation Based on Occupancy and Movement Prediction

摘要

The rule-based CA for simulating the evacuation process of single room with one exit is presented. Analogically to the Floor-Field model, the presented model is based on the movement on rectangular lattice, driven by the potential field generated by the exit. Several ideas of decision-making allowing the agent to choose an occupied cell are implemented, to reflect the observed behaviour in high densities. The velocity of pedestrians is represented by the updating frequency of the individuals. To calibrate model parameters, an experiment "leaving the room" was organized. Based on the observed behaviour, the influence of parameters is discussed and several modifications axe suggested.
