Abstract
In this study, pedestrian flow considering group especially for dyads is modelled in cellular automata (CA). Rigid body approximation is made based on the assumption of that the dyads are bonded with strong psychophysical relationship and have strong intention to stay together. Multi cell CA is applied for dyads and transition rules associating to their stress reducing behaviour are designed. Simulations are carried out to reproduce pedestrian flow in a pavement. Investigations are carried out to clarify how proportion of dyad and pedestrian density affect the pedestrian flow and spatial pattern of dyads. Although it has been known that dyads keeps line-abreast pattern at low density flow and river-like pattern at high density flow by observation study, but this is the first study which considers the detailed mechanisms to reproducing such phenomena by modelling and simulation.
