Abstract: Summary We investigate traffic on preexisting ant trails using minimal cellular automaton models. We focus on generic properties of the models like the coarsening of particles and the fundamental diagrams. Crucial differences between the biand the unidirectional model are also discussed. However, based on the coarsening behaviour both models belong to the same universality class. Furthermore it will be shown how coarsening in both models can be understood in terms of different kinds of dynamically induced disorder.
