Abstract

A method for presenting a route includes receiving a starting point and a destination point and computing a route that includes a route segment between the two points. The method further includes determining, based on a user'"'"'s travel history, whether the route segment is an unfamiliar segment, and identifying, based on the user'"'"'s travel history, a road that is familiar to the user. The method includes providing, in a format that distinguishes the familiar road from the computed route, the computed route and the familiar road relative to the unfamiliar segment for presentation of the familiar road within a scaled range of the unfamiliar segment.

Claims

1. A method for determining a route, the method comprising:

receiving a starting point and a destination point;

providing, in a format that distinguishes the familiar road from the computed route, the computed route and the familiar road relative to the unfamiliar segment for presentation of the familiar road within a scaled range of the unfamiliar segment.

2. The method of claim 1 wherein receiving the starting point comprises determining a present position of the user.

3. The method of claim 1 wherein receiving the starting point and the destination point includes prompting a user to enter the starting point and the destination point.

4. The method of claim 1 wherein computing the route comprises:

retrieving mapping data from a map source; and

using the mapping data to create the computed route.

5. The method of claim 1 further comprising determining a plurality of roads on which the user has traveled and storing the plurality of traveled roads.

6. The method of claim 5 wherein determining the plurality of traveled roads includes using an electronic positioning system to track the user'"'"'s position while the user is traveling and using a map source to correlate the user'"'"'s position with a road.

7. The method of claim 5 wherein identifying the familiar road includes:

searching the plurality of traveled roads to identify a portion of a traveled road that falls within the scaled range of the unfamiliar segment, wherein the portion of the traveled road within the scaled range is a portion on which the user has not traveled.

8. The method of claim 5 wherein identifying the familiar road includes:

searching the plurality of traveled roads to identify a portion of a traveled road that falls within the scaled range of the unfamiliar segment, wherein the portion of the traveled road within the scaled range is a portion on which the user has traveled.

9. The method of claim 5 wherein identifying the familiar road includes:

searching the plurality of traveled roads to identify a plurality of traveled roads that fall within the scaled range of the unfamiliar segment; and

selecting the familiar road from the identified plurality of traveled roads based on a distance between each of the identified traveled roads and the unfamiliar segment and a frequency with which the user has traveled on each of the identified plurality of traveled roads.

10. The method of claim 1 further comprising:

determining an alternative route from the starting point to the destination point that includes the familiar road instead of the unfamiliar segment; and

providing the alternative route for presentation to the user.

11. A system for determining a route, the system comprising:

a routing module configured to receive a starting point and a destination point, to compute a route from the starting point to the destination point, wherein the computed route comprises a route segment, to determine, based on a user'"'"'s travel history, whether the route segment is an unfamiliar segment, to identify, based on the user'"'"'s travel history, a road that is familiar to the user, and to provide, in a format that distinguishes the familiar road from the computed route, the computed route and the familiar road relative to the unfamiliar segment for presentation of the familiar road within a scaled range of the unfamiliar segment.

12. The system of claim 11 further comprising a positioning system configured to determine the starting point based on a current position of a device associated with the user.

13. The system of claim 11 further comprising:

a positioning system configured to track the user'"'"'s position while the user is traveling;

a map source configured to correlate the position of the user with a road on a map; and

a storage mechanism that stores a plurality of roads on which the user has traveled.

14. The system of claim 13 wherein the routing module is further configured to search the plurality of traveled roads, to identify a plurality of traveled roads that fall within the scaled range of the unfamiliar segment, and to select the familiar road from the identified plurality of traveled roads based on a distance between each of the identified traveled roads and the unfamiliar segment and a frequency with which the user has traveled on each of the identified plurality of traveled roads.

15. A computer readable medium containing programming instructions for determining a route, the programming instructions for:

receiving a starting point and a destination point;

computing a route from the starting point to the destination point, wherein the computed route comprises a route segment;

determining, based on a user'"'"'s travel history, whether the route segment is an unfamiliar segment;

identifying, based on the user'"'"'s travel history, a road that is familiar to the user; and

providing, in a format that distinguishes the familiar road from the computed route, the computed route and the familiar road relative to the unfamiliar segment for presentation of the familiar road within a scaled range of the unfamiliar segment.

16. A method for presenting a route, the method comprising:

receiving a route from a starting point to a destination point, wherein the route comprises a route segment;

determining, based on a user'"'"'s travel history, whether the route segment is an unfamiliar segment;

determining, based on the user'"'"'s travel history, whether there is a familiar road associated with the unfamiliar segment that is familiar to the user;

presenting the route; and

in response to determining the familiar road is within a scaled range of the unfamiliar segment, presenting the familiar road relative to the unfamiliar segment in a format that distinguishes the familiar road from the route.

17. The method of claim 16 further comprising determining a plurality of roads on which the user has traveled and storing the plurality of traveled roads.

18. The method of claim 17 wherein determining the plurality of traveled roads includes using an electronic positioning system to track the user'"'"'s position while the user is traveling and using a map source to correlate the user'"'"'s position with a road.
