There are several ways to study pedestrian dynamics such as the macroscopic hydrodynamics molecular dynamics with social force and cellular automata (CA) with mean field approach In recent years the cellular automata approach has received growing interest from researchers Because this approach is not only to save the computing time but also to reduce the complexity of the problem In this presentation we report the study of the conformation of congestion in a "T" intersection by using a cellular automata procedure with multi-floor fields By using the multi-floor fields we can mimic the pedestrian flow from several entrances to different exits firstly and we can simulate the different pedestrian speed by changing the controlling parameter Our results show there are some kinds of phase transition in this system (C) 2010 Elsevier B V All rights reserved
