Abstract:

The (qualitative) relation between pedestrian flow and density has been shown to follow a common pattern on multiple real life situations. This pattern distinguishes between a free-flow regime (for low densities) and a congested regime (for high densities). However, theoretical models, such as the Social Force Model (SFM), can handle this behavior if the right friction (or the pedestrian relaxation time) is set. We carried out statistical and numerical tests in order to match our SFM simulations with experimental data on the Jamaraat bridge (pedestrians walking along a straight corridor). We concluded that fittings should not care on the friction (or the pedestrian relaxation time) itself, but on other "reduced" parameters with fewer degrees of freedom.
