Abstract
A method for representing a route along a road network in a geographic region is disclosed. A database includes data representations of intersections of roads in the geographic region. Associated with the data representation for each intersection of roads are data indicating one or more nominal paths through the intersection. The nominal paths through an intersection identify, for each road segment by which the represented intersection can be entered, one and only one road segment from which the represented intersection is exited. The route is represented by indicating each intersection at which the route deviates from the nominal path into the intersection.
