Abstract: Based on the idea of behavioral modeling and Tajima model, an extended lattice gas model is proposed to simulate pedestrian evacuation from a hall by considering the pedestrians’ subconscious behaviors under different space environments, which reflect the pedestrians’ preferential direction choice and decision behaviors. The pedestrian dynamics and the evacuation efficiency in different scenarios, such as the sizes of space, the preferential direction strengths of subconscious behavior, different widths of exit, system sizes and pedestrian densities are investigated by computer simulation, respectively. The simulation results show that the presented model can capture some essential features of pedestrian evacuation, e.g., arching phenomenon. Furthermore, the subconscious behavior can effectively improve evacuation efficiency. In addition, the scaling relations of the saturation flow and evacuation time on the width of exit are also obtained.

Key words: pedestrian flow, evacuation dynamics, subconscious effect, lattice gas model
