Evacuation problems constitute a cornerstone of pedestrian studies and exhibit many nontrivial effects. In cellular automata models the parallel update is often used, even though other updates relevant to pedestrians have been proposed. In this work we first study a room evacuation model with random and frozen shuffle updates. We then design a hybrid shuffle update, that interpolates between the random and frozen shuffle updates and is therefore realistic in a greater variety of situations. Outflow currents, evacuation times and queue shapes are studied for the three updates.
