Simulation of merging pedestrian streams at T-junctions: Comparison of density definitions

Abstract

We study merging pedestrian streams at T-junctions using the Floor Field Cellular Automata Model. The discreteness of the underlying lattice of the cellular automaton model limits the resolution of the predicted densities. We therefore compare different methods for the determination of the density. In particular we consider a discrete version of the Voronoi method which allows to define individual densities for each pedestrian.
