We study dynamic self-organisation and order-disorder transitions in a two-dimensional system of self-propelled particles with aligning interactions. Our model is a variation of the Viscek model, where aligning interactions arise from group collisions and the particles repel each other at short distances. We use computer simulations to measure the orientational order parameter for particle velocities as a function of intensity of internal noise and particle density and construct a dynamical phase diagram for the system. We discuss the analogy between the dynamical ordering and order-disorder transitions in magnetics.
