Case I: average evacuation time of all simulations trials with different friend-group densities (high friend-group density where the proportion of pedestrians in groups to total pedestrians is as high as 80% and low friend-group density where the proportion of that is only 20%) and different group sizes (single, two, three and four). The initial number of pedestrians in the waiting hall is 600 in each trial.
