This brief report presents a model to characterize evacuees' response to environmental stimuli during emergency egress, especially in smoke and fire condition. The model is developed in consistency with stress theory, which explains how an organism reacts to environmental stressors. We integrate the theory in the well-known social-force model and apply the model to simulate crowd evacuation in fire emergency. Part of the algorithm has been tested in FDS+EVAC.
