ABSTRACT

Ants are social insects and generally experimentally tractable. For these reasons, ants are favored by researchers regarding their own crowd behavior. Based on the data gathered from our previous ant evacuation experiments, 鈥渟elfish evacuation behavior鈥� was not observed in the ants' experiments under stress conditions. To extend our understanding of the topic, we constructed a cellular automaton model to simulate the behaviors of ants in stress situations. Ant body size, shape, and actual speed gathered from previous ant evacuation experiments, were taken into account in our model. In previous ants' experiment of our work, a filter paper with the repellent substance was located on the opposite side of the experimental chamber from the exit. Inspired by this experiment, parameter D was introduced in our model, which represented the drift to move forward (toward the exit, away from the repellent substance). Every ant (An) in the room had the same D value. In our model, N ants were initially distributed randomly in the room and the sequential update rule was adopted. Considering of the temporal evolution of the number of ants escaping within each exit size, we presented experimental result of each exit width and used our model to simulate ants escaping through that exit width. Subsequently, some factors affecting evacuation efficiency were also studied.
