Spatio-temporal distribution of users. Spatio-temporal distribution of user: (a) Distribution of users during the first procession between 11:00 and 12:30 (Interval (a)); (b) Distribution during the second procession between 13:00 and 14:30 (Interval (b)); (c) Distribution during the firework display between 17:00 and 17:30 (Interval (c)); (d) Distribution during the break between 14:30 and 17:00. It is visible that people amass along streets where the processions take place and around the river basin during the fireworks. During the break, however, the accumulation is much lower and concentrated around bus and metro stations.
