Abstract

A method and system that provides end users with the ability to exchange routing data. A route recorder application on a first computing system provides a first end user with the ability to define a route formed of specific road segments and store data that represent the route in a data file. The data file is distributed to a second end user who uses the data that represent the route in a second computing system to provide guidance for following the route.

Claims

1. A method of providing users with the ability to exchange route information, the method comprising:

a first user with a first computing system, defining a route from an origin to a destination and storing data that represent the road segments comprising the route in a data file;

distributing the data file to a second user that is different from the first user; and

providing the second user with guidance for following the route on a second computer system using the data file.

2. The method of claim 1 wherein the step of distributing includes providing a physical medium with the data file stored thereon to the second user.

3. The method of claim 1 wherein the step of distributing includes transferring the data file wirelessly to the second computing system of the second user.

4. The method of claim 1 wherein the first user with the first computer system accesses a server over a network to define the route.

5. The method of claim 1 further comprising:

determining a position of a vehicle in which the first user is traveling;

identifying road segments on which the vehicle is traveling; and

using the identified road segments to define the route that is stored in the data file.

6. The method of claim 1 wherein said first computing system is a standalone system.

7. The method of claim 1 wherein said first computing system is a vehicle navigation system.

8. The method of claim 1 wherein the data that represent the route in the data file include ID'"'"'s of data records that represent the road segments that form the route.

9. The method of claim 1 wherein the data that represent the route in the data file include geographic coordinates of the road segments that form the route.

10. The method of claim 1 wherein the data that represent the route in the data file include street names of the road segments that form the route.

11. The method of claim 1 wherein the data that represent the route in the data file include directions and distances along road segments that form the route.

12. A system that enables users to exchange route information, the system comprising:

a first computing system implementing a route recorder application, said route recorder application provides a first user the ability to create and store a data file containing data indicating a route traveled by the first user between an origin and a destination, wherein said data file being capable of being used by a second computing system to provide a second user that is different from the first end user with guidance for following the route traveled by the first user.

13. The system of claim 12 wherein said data file identifies road segments traveled by the first user.

14. The system of claim 12 wherein said data file identifies maneuvers made by the first user.

15. The system of claim 12 wherein said data file identifies coordinates along the route traveled by the first user.

16. The system of claim 12 wherein said data file identifies directions and distances traveled by the first user.

17. The system of claim 12 wherein the first computing system is a navigation system.

18. A method that enables users to exchange route information, the method comprising:

providing a first user with data defining a trail route from an origin to a destination;

accepting input from the first user that changes the trial route to a new route from the origin to the destination;

storing data that represent the new route as the trail route changed in accordance with input from the first user in a data file;

distributing the data file to a second user that is different from the first user; and

using the data that represent the route in a second computing system to provide the second user with guidance for following the route.

19. The method of claim 18 wherein said data file identifies maneuvers for the route.

20. The method of claim 18 wherein said data file identifies roads for the route.

21. The system of claim 18 wherein said data file identifies directions and distances along the route.
