Abstract We study two new models of two particle species invading a surface from opposite sides. Collisions of particles of different species lead to the formation of congestion fronts. One of the models implements a reversible process whereas in the other model the congestion front forms irreversibly. For both models we find that the congestion fronts are self-affine but with different roughness exponents. For low densities the system does not congest and we find a phase transition between a phase of freely moving particles and a congestion phase. Highlights • We observed the formation of islands and multiple congestion fronts. • We found that the interfaces that the model formed are self-affine. • We found a phase transition and established the phase diagram.
