Vibrations, Shocks and Noise A new crowd movement modeling for pedestrians who hold hands

The aim of this communication is to propose a new crowd movement modeling considering a new particular subgroup behavior: pedestrians holding hands. The first step in this study is to improve our 2D crowd movement modeling [1-3] introducing the orientation of each pedestrian, rarely used in literature. The next step is to describe the particular subgroup behavior of the pedestrians who hold hands. An at-a-distance velocity of deformation allows one to control the interaction between linked pedestrians. The proposed model takes into account the effects of the subgroup as a continuous deformation within the particular subgroup of pedestrians who hold hands while existing methods in literature describe the cohesion of the “normal” subgroup with external forces. Finally, numerical simulations will be presented to study the influence of the pedestrian’s orientation on his movement and to compare subgroup behavior models.
