Abstract

A method of operation of a navigation system includes: determining a route classification of a candidate route; determining a misclassification of the route classification for identifying the candidate route misclassified; updating the route classification based on the misclassification for reclassifying the candidate route; generating a travel route based on the candidate route with the route classification updated for displaying on a device.

Claims

1. A method of operation of a navigation system comprising:

determining a route classification of a candidate route;

determining a misclassification of the route classification for identifying the candidate route as misclassified;

updating the route classification based on the misclassification for reclassifying the candidate route; and

generating a travel route based on the candidate route with the route classification updated for displaying on a device.

2. The method as claimed in claim 1 wherein determining the misclassification includes determining the misclassification of the candidate route within a neighboring area.

3. The method as claimed in claim 1 wherein updating the route classification includes reclassifying the candidate route based on a neighboring area where the candidate route is identified.

4. The method as claimed in claim 1 wherein updating the route classification includes updating the route classification for the candidate route unconsidered for generating the travel route.

5. The method as claimed in claim 1 wherein updating the route classification includes updating the route classification based on a user'"'"'s preference for reclassifying the candidate route.

6. A method of operation of a navigation system comprising:

determining a route classification of a candidate route;

determining a misclassification of the route classification for identifying the candidate route misclassified;

updating the route classification based on the misclassification for reclassifying the candidate route; and

generating a travel route to a target destination based on the candidate route with the route classification updated for displaying on a device.

7. The method as claimed in claim 6 wherein determining the misclassification includes determining the misclassification based on a travel cost meeting or exceeding a reclassification threshold.

8. The method as claimed in claim 6 wherein updating the route classification includes reclassifying the candidate route based on a travel condition for improving the route classification.

9. The method as claimed in claim 6 wherein generating the travel route includes generating the travel route based on a preferred path for considering the candidate route reclassified.

10. The method as claimed in claim 6 wherein updating the route classification includes upgrading the route classification for reclassifying the candidate route.

11. A navigation system comprising:

a candidate module for determining a route classification of a candidate route;

an estimation module, coupled to the candidate module, for determining a misclassification of the route classification for identifying the candidate route misclassified;

a reclassification module, coupled to the estimation module, for updating the route classification based on the misclassification for reclassifying the candidate route; and

a route module, coupled to the reclassification module, for generating a travel route based on the candidate route with the route classification updated for displaying on a device.

12. The system as claimed in claim 11 wherein the estimation module is for determining the misclassification of the candidate route within a neighboring area.

13. The system as claimed in claim 11 wherein the reclassification module is for reclassifying the candidate route based on a neighboring area where the candidate route is identified.

14. The system as claimed in claim 11 wherein the reclassification module is for updating the route classification for the candidate route unconsidered for generating the travel route.

15. The system as claimed in claim 11 wherein the reclassification module is for updating the route classification based on a user'"'"'s preference for reclassifying the candidate route.

16. The system as claimed in claim 11 wherein the route module is for generating a travel route to a target destination based on the candidate route with the route classification updated for displaying on the device.

17. The system as claimed in claim 16 wherein the estimation module is for determining the misclassification based on a travel cost meeting or exceeding a reclassification threshold.

18. The system as claimed in claim 16 wherein the reclassification module is for reclassifying the candidate route based on a travel condition for improving the route classification.

19. The system as claimed in claim 16 wherein the route module is for generating the travel route based on a preferred path for considering the candidate route reclassified.

20. The system as claimed in claim 16 wherein the reclassification module is for upgrading the route classification for reclassifying the candidate route.
