Properties of pedestrians walking in line without density constraint

Résumé

This article deals with the study of pedestrian behaviour in one-dimensional traffic situations. We asked participants to walk either in a straight line with a fast or slow leader, or to form a circle, without ever forcing the conditions of density. While the observed density results from individual decisions in the line case, both density and velocity have to be collectively chosen in the case of circle formation. In the latter case, interestingly, one finds that the resulting velocity is very stable among realizations, as if collective decision was playing the role of an average. In the line experiment, though participants could choose comfortable headways, they rather stick to short headways requiring a faster adaption - a fact that could come from a ``social pressure from behind''. For flows close to the jamming transition, the same operating point is chosen as in previous experiments where it was not velocity but density that was imposed. All these results show that the walking values preferred by humans in following tasks depend on more factors than previously considered.
