Abstract: A multi-speed cellular automaton is used to simulate the escaping pedestrian flow in a corridor under the open boundary condition. Keeping the total number of people fixed, and pedestrians moving in different speeds, we studied the evolution of pedestrian flow by varying the parameters of system size. The relationships between parameters of system size and the transition time are discussed in this paper. It is found that the transition timetcclosely depends on the width(W)of corridor and the maximum speedVmaxof people, it scales astc∝W-0.80±0.06, and$t_c\propto V_{\rm max}^{-\alpha}$, in which α increases with the width of doors. However, the width of doors and the strength of drift have little influence on the transition time.
