according to the first assumption.
For the first 130 meters of the procession route that
was occupied by the pedestrians, the number of
devotees participating in the procession was
estimated using Eq. 5. Considering the varying road
widths of the procession route, the number of
devotees within the first 130 meters of the route was
estimated to be about 21,801 pedestrians. As the
procession proceeded to move forward, it was Fig. 9 People reaching the Andas aggressively

active devotees ahead of the parade was constant. Similar behavior was also observed when

high densities are the main causes of serious injuries
to the participating pedestrians.
