Abstract：An improved floor field model is proposed to simulate the pedestrian evacuation behavior in a room with multiple exits by modifying the static floor field. The modified static floor field is determined additionally by two cognitive coefficients of exit width and congestion degree around the exits. The logit-based discrete choice principle is used to govern the initial exit selection strategy based on the modified static floor field in such a scenario that pedestrians are distributed in the room's specified zone. Simulation results show that the proposed model can better perform the evacuation process. Sensitivity analyses of the model parameters are also presented.
