摘要： Methods and systems are provided for generating an electronic map display. In one implementation, a method is provided for determining a route distance based on information for a route, comparing the route distance with a distance threshold, generating a list of points of interest (POIs) when the route distance is less than the distance threshold, the list of POIs identifying POIs that are located along the route, grouping the POIs into one or more buckets based on location, calculating POI densities of the buckets based on the POIs included in each corresponding bucket, ranking the buckets based on the POI densities, providing POI information associated with the POIs included in the ranked buckets, wherein the POI information is provided based on the ranking of the buckets, and generating an electronic map display with the POI information.

摘要： Driving directions are presented where a maneuver in the driving directions includes a road symbol and an action symbol. A road symbol identifies the road involved in the particular maneuver, and an action symbol identifies an action to be performed to execute the particular maneuver. In one example, a road symbol, an action symbol and narrative text may be presented in displayed or printed driving directions. In another example, a road symbol and an action symbol may be used to describe a maneuver presented by an on-board or mobile navigation system when the vehicle in which the navigation system is present approaches the point at which the maneuver is to be taken. The road symbol and the action symbol may be presented with, or without, narrative driving directions.

摘要： Techniques are provided for reducing the number of maneuvers presented in narrative driving directions for a route from an origin location to a destination location. Maneuvers are combined to reduce the number of maneuvers presented. Maneuvers may be combined based on a maneuver being associated with a highway interchange or maneuvers including a shared reference to a particular road.
