Abstract
A method, system, and/or computer program product automatically generates route directions based on signpost data. A calculated route from an origin to a destination includes multiple decision points where a user has more than one option to take. Geo-stamped images of signposts located at each decision point from the multiple decision points are received, and one or more series of signposts is compiled, where each series has a common signpost content. Conflicts in any overlapping series are resolved by using a measure of relative density of signpost content, and one or more decision points of the calculated route are replaced with instructions referring to the common signpost content of the series of signposts. Geo-stamped images of signposts of the series of signposts having the common signpost content are then displayed in a motor vehicle.
