The dynamical behaviors of pedestrians outside a hall is investigated by using the extended lattice-gas model with different maximum velocities. A numerical simulation illustrates that fast and slow pedestrians will affect some dynamical characteristic from the choking flow to the decaying flow. In the choking-flow region, the scaling relation of crowd flow rate and the evacuation time are obtained, respectively. The slow pedestrians, initial density of walkers and the location of the exit influence the evacuation time.
