Modelling Counterflow Situations of Pedestrian Traffic — •Maike Kaufman, Tobias Kretz, and Michael Schreckenberg — Universität Duisburg-Essen, Physik von Transport und Verkehr, Lotharstr. 1, D-47057 Duisburg

A Cellular Automaton-based model of Pedestrian Dynamics which encorporates intelligent agent behavior in counterflow situations is presented.

The described model is an extention of the F.A.S.T. model of Pedestrian Dynamics. It is discrete in space and time and probabilistic in the pedestrians choice of direction of movement. An agent chooses his next position from the set of accessible cells allowed by his velocity. This choice is made according to a precomputed probability which depends on the agent's neighborhood. In this work a spheric direction-dependant potential surrounds each pedestrian. It is repulsive for agents walking in opposite directions and attractive for agents moving in the same direction, thus ensuring that pedestrians are able to avoid collisions and follow persons in front of them. This modification of the model allows for reproduction of lane formation and higher fluxes at critical densities.
