Evacuation Simulation in the Narrow Stair with Revised Social Force Model

Abstract:

In this paper, a revised social force model in the stairs are discussed. Considering the influence of the gravity to the pedestrians in the stairs, we improve the model by adding the gravity factor, which makes the simulation more reality. In additional, we simplify the direction model of the psychological force between pedestrians considering the narrow space of the stair, and this will refine the computational efficiency dramatically. Furthermore, we also discussed the construction of the building models for the practical simulations. The experimental results in this paper shows the valid of the model.
