Employing the social force pedestrian model for simulating evacuation scenarios — •Torsten Werner — Dresden University of Technology, Mommsenstr. 13, D-01069 Dresden, Germany

The social force model by Helbing et. al. is currently the most advanced approach for simulating pedestrian motion. It solves Newton’s equation for each individual and considers repulsion interaction, friction forces, dissipation and fluctuations—familiar quantities to every physicist.

That model can be successfully applied to simulate real world scenarios in pedestrian movement. In particular it has already been used for modeling ship evacuation and the annual pilgrim stream at the Jamarat area near Mekka which is well known for its high densities and regular fatal accidents resulting from those dangerous densities.

A simulation software has been implemented that can handle multiple floors in real 3-dimensional buildings and other nontrivial geometries, e. g. columns and angular walls. All parameters that influence pedestrian movement can be adjusted in a way that the simulation results match available empirical data.

There are plans to use such simulation for projecting and testing new ship geometries, planning stadiums for the soccer world championship in 2006 and prior reconstruction of the Jamarat bridge.
