Abstract: A geographic database used by a navigation system includes data regarding which corners of an intersection are connected by a crosswalk and the type of crosswalk. The geographic database also includes data regarding locations of crosswalks at a location other than an intersection. Using this information, the navigation system can provide crosswalk information to a pedestrian regarding where to cross a road.

Abstract: A method of operating a navigation system determines a route between an origin and a destination and provides a photographic image showing a geographic area through which the route passes. The photographic image shows the geographic area from a land-based viewpoint. The method overlays a route highlight on the photographic image identifying a path to be traveled. The route highlight includes a symbol indicating at least one feature of the route selected from a group consisting of handicap accessible route, tree-lined route, well-lit route, quiet route, scenic route, crowded route, peaceful route, and bicycle friendly route.

Abstract: A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request for the pedestrian route between a first location inside a building and a second location inside the building is obtained. A geographic database associated with the navigation system is accessed for data representing a plurality of pedestrian paths. A solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths between the first location and the second location is determined. A guidance message that identifies a feature visible from at least one of the pedestrian paths is provided.

Abstract: A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request to calculate the pedestrian route from an origin to a destination and a walking preference for the pedestrian route identifying a feature of the pedestrian route are obtained. A geographic database associated with the navigation system is accessed for data representing at least one pedestrian path. The data representing the pedestrian path includes lighting level attribute information for the pedestrian path. A valid solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths that support the walking preference is determined.

Abstract: A data representation for an address is disclosed. The address is represented by two links. The first link is an addressed link and the second link is a routing link. The addressed link is the link associated with the address. The routing link is the link associated with a travel-to location for the address. The address may also be represented by two points. The first point is a display point and the second point is a routing point. The display point is used for displaying an address location on a map display. The routing point is used for routing a user of a navigation device to the appropriate point on a road network or pedestrian pathway for the address location.

Abstract: A method for collecting geographic data identifies a pedestrian segment associated with a path. Location information for the pedestrian segment is collected. Additionally, lighting level attribute information is collected for the pedestrian segment. The location information and the lighting level attribute information are stored in the geographic database that is stored on a computer readable storage medium.

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.

Abstract: A navigation system determines a route between a first location on a road network and a second location in a facility off of the road network. The system composes individual guidance messages for travel along a portion of the route on the road network. A pre-composed set of guidance instructions for travel in the facility along a portion of the route off of the road network are obtained from a geographic database associated with the navigation system.
