Abstract

We have modified the transition probability calculations in the lattice gas model of biased-random walkers. Adopting the collision-avoided rules, a new cellular automata model of pedestrian flow which updates in parallel is established. Using this model, we have simulated and studied the evacuation process of people in a hall. The spatial configuration of people is presented, which is more consistent with the scene of reality than that presented in the lattice-gas model. It is found that the escape timetcclosely depends on the width of the door and the initial density of people, it scales astc∝ W-0.55±0.01andtc∝ ρ0.98±0.01≈ ρ.
