Simulation of Pedestrian Flow on Floor-Stair Interface Using an Extended Lattice Gas Model

Abstract:

In this paper, an extended lattice gas model is proposed to simulate pedestrian flow on floor-stair interface by considering inner-side walking preference, turning behavior and different desired speeds. The effects of different injection rates for pedestrians from corridor on the mean velocity and occupancy are investigated, and the merging behavior, which happened on floor-stair interface, is analyzed. The simulation results show that the extended model can reproduce some essential features of pedestrian flow on stairs, such as transition of movement state at higher injection rate, merging behavior on floor-stair interface. The effects of two kind of typical structures of the floor-stair interface on pedestrian merging behavior are discussed, and merging process simulated by the model appears biased to that the corridor is connected opposite to the incoming stair.
