Empirical investigation on pedestrian dynamics in presence of groups: a real world case study

The paper reports the results of an empirical investigation on pedestrian dynamics in presence of groups. We consider a real world scenario in which an analysis of the impact of groups on the overall observed system dynamics was performed through manual counting and tracking. The simulation results are compared to empirical data and they show that the adopted model is able to produce quantitatively plausible results in situations characterised by the presence of groups of pedestrians.
