3.7 Push Formation
It was noticeable that pedestrians behind the
Andas cleared the area and used it to rush towards
carriage at each time it was observed to stop moving.
This analysis aims to quantify such group
formations.

route was observed. An event was qualified to be a Fig. 5 Time-Distance Diagram of the 2019
