Operational walking dynamics of crowds modelled by means of linear regression

Research output: Chapter in Book/Conference proceedings/Edited volumeConference contributionScientificpeer-review


In this study the influence of the interaction characteristics on operational walking dynamics within a crowd is investigated. This paper specifically studies the influence of the distance headway, time headway, angle of sight, angle of interaction, the walking speed and the number of pedestrians located nearby on a pedestrians’ change in speed and direction. To the authors’ best knowledge, this is the first time that the combined effect is quantified of the characteristics of the interactions between pedestrians on the operational walking dynamics of pedestrians. The walking speed and number of pedestrians in close proximity are found to influence the adaptation of speed as well as direction. The other characteristics of the interaction affect either the change in speed (i.e. distance headway and interaction angle) or the change in direction (i.e. time headway and angle of sight). The results of this study provide a strong indication that the density experienced by pedestrians is not the only characteristic of the crowd affecting pedestrians’ operational walking dynamics. Consequently, also the other characteristics of the interaction will need to be taken into account in pedestrian flow theory and simulation models in order to correctly model crowd movements.
