Abstract: A method of controlling an autonomous vehicle, which is movable on a surface, includes obtaining a model (world model) of the surface, by which each area of the surface is associated with a probabilistic occupancy score; determining, on the basis of the area's position, an occupancy threshold to be applied to an area of the surface; enabling movement of the AV into the area if the associated occupancy score is less than the determined occupancy threshold; and otherwise disabling movement into the area.
