The physical boundary between two road reserve segments that prevents vehicular access; or the boundary of applicability of a road name between two road reserve segments that do not belong to the same road where one road runs into another (and hence there is no physical boundary or indication). The type of physical boundary relevant in each case is defined by the VEHICULAR_ACCESSS_FLAG attribute. The second use of the ACCESS_RESTRICTION table, as a barrier between applicability of road name is used simply for the purposes of graphical presentation. The difference in road name applicability can be determined from the links between the road reserve segment and the road to which it belongs. However, in most cases the barrier between roads would not be displayed on a map because it is obvious from the shapes of surrounding roads. This second use of the table caters for the case where it is not visibly obvious where one road ends and the next begins.
