Analysis on a Single Segment of Evacuation Network
Takahiro Ezaki, Daichi Yanagisawa and Katsuhiro Nishinari
We investigate the behavior of pedestrian evacuation with steady inflow using the floor field model. By simulations, the metastable state induced by conflicts of pedestrians is observed. The system is controlled by parameters of the inflow and competitiveness of the pedestrians, and large inflow leads to a congested situation. The critical condition of the transition and mathematical expressions of outflow for both center and corner exits are theoretically derived.
