Abstract

An approach is provided for providing navigational assistance using guidance markers. One or more parameters associated with a guidance marker are received. A score is determined for the guidance marker using the one or more parameters. The guidance marker is selected based, at least in part, on the score for use in navigating along a path. Further, at least one other score can be determined for at least one other guidance marker and the other score may be compared with the score. The selection can be based on the comparison. A starting point and a destination point can be received. Further, navigational assistance data may be determined based on the guidance marker, the starting point, and the destination point. The navigational assistance data can be caused to be presented on a device.

Claims

1. A method comprising:

receiving one or more parameters associated with a guidance marker;

determining a score for the guidance marker using the one or more parameters; and

selecting the guidance marker based, at least in part, on the score for use in navigating along a path.

2. A method of claim 1, wherein the one or more parameters include a distance parameter, a visibility parameter, an obstruction parameter, a path parameter or a combination thereof

3. A method of claim 1, further comprising:

determining at least one other score for at least one other guidance marker; and

comparing the at least one other score with the score, wherein the guidance marker is selected based on the comparison.

4. A method of claim 1, further comprising:

determining a suitability weighting for the guidance marker based, at least in part, on a type of travel along the path,

wherein the score is determined based, at least in part, on the suitability weighting.

5. A method of claim 1, further comprising:

receiving a starting point and a destination point;

determining the path based, at least in part, on the starting point and destination point;

associating the guidance marker to the path;

determining navigational assistance data based, at least in part, on the guidance marker and the association; and

causing, at least in part, actions leading to the presentation of the navigational assistance data on a device.

6. A method of claim 1, further comprising:

receiving a starting point and a destination point;

determining the path based, at least in part, on the starting point and destination point;

determining a need for at least one other path based on the score;

determining the at least one other path based on the guidance marker; and

determining navigational assistance data based, at least in part, on the at least one other path and the guidance marker.

7. A method of claim 1, wherein the score comprises a sum of parameter scores for each of the parameters and one or more of the parameter scores are based, at least in part, on guidance marker context information relevant to the guidance marker.

8. A method of claim 7, wherein the guidance marker context information includes weather information, time information, traffic information, or a combination thereof.

9. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive one or more parameters associated with a guidance marker;

determine a score for the guidance marker using the one or more parameters; and

select the guidance marker based, at least in part, on the score for use in navigating along a path.

10. An apparatus of claim 9, wherein the one or more parameters include a distance parameter, a visibility parameter, an obstruction parameter, a path parameter or a combination thereof

11. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

determine at least one other score for at least one other guidance marker; and

compare the at least one other score with the score, wherein the guidance marker is selected based on the comparison.

12. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

determine a suitability weighting for the guidance marker based, at least in part, on a type of travel along the path,

wherein the score is determined based, at least in part, on the suitability weighting.

13. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

receive a starting point and a destination point;

determine the path based, at least in part, on the starting point and destination point;

associate the guidance marker to the path;

determine navigational assistance data based, at least in part, on the guidance marker and the association; and

cause, at least in part, actions leading to the presentation of the navigational assistance data on a device.

14. An apparatus of claim 9, wherein the apparatus is further caused, at least in part, to:

receive a starting point and a destination point;

determine the path based, at least in part, on the starting point and destination point;

determine a need for at least one other path based on the score;

determine the at least one other path based on the guidance marker; and

determine navigational assistance data based, at least in part, on the at least one other path and the guidance marker.

15. An apparatus of claim 9, wherein the score comprises a sum of parameter scores for each of the parameters and one or more of the parameter scores are based, at least in part, on guidance marker context information relevant to the guidance marker.

16. An apparatus of claim 15, wherein the guidance marker context information includes weather information, time information, traffic information, or a combination thereof.

17. A computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

receiving one or more parameters associated with a guidance marker;

determining a score for the guidance marker using the one or more parameters; and

selecting the guidance marker based, at least in part, on the score for use in navigating along a path.

18. A computer-readable storage medium of claim 17, wherein the apparatus is caused, at least in part, to further perform:

determining at least one other score for at least one other guidance marker; and

comparing the at least one other score with the score, wherein the guidance marker is selected based on the comparison.

19. A computer-readable storage medium of claim 17, wherein the apparatus is caused, at least in part, to further perform:

receiving a starting point and a destination point;

determining the path based, at least in part, on the starting point and destination point;

associating the guidance marker to the path;

determining navigational assistance data based, at least in part, on the guidance marker and the association; and

causing, at least in part, actions leading to the presentation of the navigational assistance data on a device.

20. A computer-readable storage medium of claim 17, wherein the apparatus is caused, at least in part, to further perform:

receiving a starting point and a destination point;

determining the path based, at least in part, on the starting point and destination point;

determining a need for at least one other path based on the score;

determining the at least one other path based on the guidance marker; and

determining navigational assistance data based, at least in part, on the at least one other path and the guidance marker.
