Abstract: Abstract This contribution considers a new method for dynamic medium scale navigation in microscopic pedestrian simulators. The concept of static navigation floor fields is extended to a dynamic interpretation following ideas of (Kretz, T, Journal of Statistical Mechanics: Theory and Experiment, P03012, 2009) and (Hartmann, D, New Journal of Physics 12(4):043032, 2010) within a cellular automaton approach. Every few simulation steps a new floor field for navigation is constructed by solving the Eikonal equation on the dual grid of the underlying cellular automaton discretization. By considering other pedestrians directly in the construction of the floor field, the realism of the simulations is significantly increased. The new contribution of our work is to additionally consider walking directions of pedestrians. This leads to a significant increase in the realism of simulations. The increased realism of the new concept is underlined by simulations of various example scenarios proposed in the literature. These show that the method is capable of reproducing a number of phenomena, e.g. lane formation.
