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 end users with the ability to exchange routing data, the method comprising:

providing a route recorder application on a first computing system, wherein the route recorder application provides a first end user with the ability to define a route formed of specific road segments and store data that represent each of the specific road segments comprising the route in a data file;

distributing the data file to a second end user, wherein the second end user is different than the first end user; and

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

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 end user.

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

4. The method of claim 1 wherein the route recorder application is located on a server that the first end user accesses over a network.

5. The method of claim 4 wherein the network includes the Internet.

6. The method of claim 1 further comprising:

with the route recorder application, providing the first end user with data defining a trial route; and

accepting input from the first end user that changes the trial route,

wherein the data that represent the route that are stored in the data file by the route recorder application include data that represent the trial route as changed in accordance with the input from the first end user.

7. The method of claim 1 further comprising:

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

identifying road segments upon which the vehicle is traveling; and

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

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

9. 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.

10. 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.

11. 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.

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

13. The method of claim 1 wherein the route leads to a destination at which the first user and the second user plan to meet.

14. The method of claim 1 further comprising:

on the first computing platform, determining a convenient place for the first user and the second user to meet taking into account current locations of the first user and the second user,

wherein an origin of the route is the current location of the second user and a destination of the route is the convenient place for the first user and the second user to meet.

15. The method of claim 1 wherein the second computing system is a vehicle navigation system.

16. The method of claim 1 wherein the second computing system provides the second end user with guidance for reaching an origin of the route.

17. The method of claim 1 wherein the second computing system incorporates the route provided from the first user into another route.

18. A method of providing end users with an ability to exchange routing data, the method comprising:

using a positioning system to determine positions of a first end user as the first end user travels along a route formed of road segments;

using the positions of the first end user to determine the route traveled by the first end user;

storing data that indicate the route traveled by the first end user in a data file; and

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

19. The method of claim 18 further comprising:

after the step of storing, distributing the data file to the second end user.

20. A method of providing end users with an ability to exchange routing data, the method comprising:

a first user with a first computing system, defining a route formed of specific road segments and storing data that represent the route comprising the specific road segments in a data file;

distributing the data file to a second computing system;

with the second computing system, using the data that represent the route to formulate guidance for following the route; and

with the second computing system, providing the guidance to follow the route to a second end user, wherein the second end user is different than the first end user.
