The system may aggregate the drive information to determine at least one host vehicle drivable path, store a representation of the drivable path, generate a road surface representation for each road surface, store the road surface representations, assign a detected road feature to a road surface representation, and distribute the map to at least one host vehicle navigation system for use in navigating the host vehicle along the road segment relative to the host vehicle drivable path.",
