摘要:
A computer implemented method of compressing a plurality of TPEG format traffic messages is provided. The method forms a template containing the data values of fields of a message management container, an event container and a location container and forms a global data set representing a base time of the traffic messages and data indicating the geographic region. The method creates compressed TPEG traffic messages comprising a template identification indicating the template and data values of the fields of the message management container, the event container and the location container not included in the template or global data set.
摘要:
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.

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.

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.
摘要:
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.
