A Cellular Automaton Model with Varied Walk Velocity
Authors: , , ,
Abstract: This paper presents a new cellular automaton model in which the neighborhood is the extended Moore’s neighborhood(r = 2) and each cell’s walk velocity is the function of inter-person distance. This model can simulate pedestrian movement with different velocity through letting pedestrian move more than one cell. In the evacuation process, the moving rules are determined by three functions: exit function, direction function and velocity func- tion. An emergency evacuation example is used to illustrate the validity of the new presented varied walk velocity cellular automaton. Comparing the results obtained by the non-varied walk velocity cellular automaton model and the new model, it is demonstrated that the new model is more valid to simulate evacuation and the evacuation time is shorter.
