Abstract

Traffic patterns are monitored for adherence of a user to a suggested route. Deviations from suggested routes are recorded for later upload and/or analysis. Repeated deviations by one, or more, users following similar navigation routes are identified for possible changes in maps and/or routing algorithms.

Claims

1. A method for use with a vehicle that travels actual routes and is equipped with a navigation device that recommends suggested routes, the method comprising:

receiving a first suggested route from the navigation device;

detecting a first deviation between the first suggested route and a first actual route traveled by a vehicle; and

storing a first deviation data related to the first deviation at the navigation device;

detecting a second actual route traveled by the vehicle, the second actual route including following the first suggested route past the first deviation; and

based at least in part on the second actual route following the first suggested route past the first deviation, erasing the first deviation data or resetting a counter associated with the first deviation data.

2. The method of claim 1, wherein the first deviation data is stored in a relatively permanent manner.

3. The method of claim 1, wherein the first deviation data is stored in a local memory of the navigation device.

4. The method of claim 1, wherein:

the detection of the first deviation includes;

receiving vehicle position data from a satellite-based global positioning system (GPS); and

determining the first deviation by comparing the vehicle position data to the first suggested route.

5. The method of claim 1, further comprising:

detecting a plurality of deviations between a plurality of suggested routes and a plurality of actual routes;

storing a set of deviation data related to the plurality of deviations; and

determining a set of repeated route deviations based, at least in part, on the plurality of deviations.

6. The method of claim 5, further comprising:

communicating the set of repeated route deviations to an external device.

7. The method of claim 1, further comprising:

communicating the first deviation data to an external device, wherein the first deviation data is displayed on a display device

8. The method of claim 1, wherein the first deviation data includes one, or more, of the following:

where the first deviation occurred, which direction a user is moving during the first deviation, the time of day of the first deviation, which suggested turn was not followed by the first deviation, a model number of the navigation device, and/or a version number of a map on which the first suggested route is based.

9. A computer program product for use with a vehicle that travels actual routes and is equipped with a navigation device that recommends suggested routes, the computer program product including a computer readable storage medium, the computer program product comprising computer program instructions that, when executed by one or more processors, cause a computing device to perform operations comprising:

receiving a first suggested route from a navigation device;

detecting a first deviation between the first suggested route and a first actual route traveled by a vehicle; and

storing a first deviation data related to the first deviation;

detecting a second actual route traveled by the vehicle, the second actual route including following the first suggested route past the first deviation; and

based at least in part on the second actual route following the first suggested route past the first deviation, erasing the first deviation data or resetting a counter associated with the first deviation data.

10. The computer program product of claim 9, wherein the first deviation data is stored in a relatively permanent manner.

11. The computer program product of claim 9, wherein the first deviation data is stored in a local memory of the navigation device.

12. The computer program product of claim 9, wherein:

detecting the first deviation between the first suggested route and the first actual route includes;

receiving vehicle position data from a satellite-based global positioning system (GPS); and

determining the first deviation by comparing the vehicle position data to the first suggested route.

13. The computer program product of claim 9, further comprising:

detecting a plurality of deviations between a plurality of suggested routes and a plurality of actual routes;

storing a set of deviation data related to the plurality of deviations; and

determining a set of repeated route deviations based, at least in part, on the plurality of deviations.

14. The computer program product of claim 13, further comprising:

communicating the set of repeated route deviations to an external device.

15. The computer program product of claim 9, further comprising:

communicating the first deviation data to an external device, wherein the first deviation data is displayed on a display device.

16. The computer program product of claim 9, wherein the first deviation data includes one, or more, of the following:

where the first deviation occurred, which direction a user is moving during the first deviation, the time of day of the first deviation, which suggested turn was not followed by the first deviation, a model number of the navigation device, and/or a version number of a map on which the first suggested route is based.

17. A computer system for use with a vehicle that travels actual routes and is equipped with a navigation device that recommends suggested routes, the computer system comprising one or more computer processors, a computer readable storage medium operatively coupled to the one or more computer processors, the computer readable storage medium having disposed within it computer program instructions that, when executed by the computer processor, cause the computer system to perform operations comprising:

receiving a first suggested route;

detecting a first deviation between the first suggested route and a first actual route; and

storing a first deviation data related to the first deviation;

detecting a second actual route traveled by the vehicle, the second actual route including following the first suggested route past the first deviation; and

based at least in part on the second actual route following the first suggested route past the first deviation, erasing the first deviation data or resetting a counter associated with the first deviation data.

18. The computer system of claim 17, wherein the first deviation data is stored in a relatively permanent manner.

19. The computer system of claim 17, wherein the first deviation data is stored in a local memory of the navigation device.

20. The computer system of claim 17, wherein the first deviation data includes one, or more, of the following:

where the first deviation occurred, which direction a user is moving during the first deviation, the time of day of the first deviation, which suggested turn was not followed by the first deviation, a model number of the navigation device, and/or a version number of a map on which the first suggested route is based.
