Abstract
A preferred route may be determined from an origin location to a destination location. The determination is made by processing directed links (e.g., one-way edges) in a graph that includes one or more links and two or more nodes. The determination of a preferred route may include an estimate of the time required at one or more intersections along alternative. Individual routing preferences, such as a preference of a rural over an urban route, also may be considered. Techniques are described that may help reduce the time required to identify a preferred route, including the identification and removal of no outlet routes before processing the directed links and techniques using particular data formats.
