Abstract
A method of operating a navigation system is disclosed. A request for a route between a first location on a road network and a second location off of the road network is received. A geographic database stored on a computer readable medium associated with the navigation system is accessed to obtain data representing a plurality of road segments including data representing a sidewalk along the road segment and data representing a crosswalk associated with the road segment. The geographic database is accessed to obtain data representing a plurality of pedestrian segments and data representing at least one orientation node providing a connection between one of the road segments and one of said pedestrian segments. A solution route comprising a series of connected road segments and a series of connected pedestrian segments between the first location and the second location is determined.
