The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A computer implemented method of providing advertisements, the method comprising:
obtaining a position of a mobile device;
determining a mode of transport of the mobile device;
if the mode of transport is public transit, providing a first advertisement message for a first point of interest to the mobile device, wherein the first point of interest is located proximate an upcoming transit stop of a transit line that the mobile device is traveling on; and
if the mode of transport is vehicle, bike or pedestrian, providing a second advertisement message for a second point of interest proximate the position of the mobile device.
2. The method of claim 1 wherein the mode of transport is determined by map matching the position of the mobile device to data representing a location of a transit line, a road segment, a bike path or a pedestrian path.
3. The method of claim 1 wherein the mode of transport is determined by evaluating the speed of travel of the mobile device.
4. The method of claim 1 wherein the second advertisement message has an associated advertising area defining a portion of a geographic region, wherein the position of the mobile device is located within the associated advertising area.
5. The method of claim 4 wherein the size of the advertising area depends on the mode of transport of the mobile device.
6. The method of claim 1 wherein the first advertisement message has an associated advertising area defining a portion of a geographic region, wherein the location of the upcoming transit stop is located within the associated advertising area.
7. The method of claim 1 further comprising:
obtaining a past position and a current position of the mobile device; and
determining a direction of travel of the mobile device.
8. A system for providing an advertisement comprising:
a processor,
an advertisement database stored on a computer readable medium associated with the processor, and
an advertising program executed on the processor, wherein the advertising program determines whether a mobile device is traveling on a public transit line, and if so, provides a first advertisement message for a first point of interest to the mobile device, wherein the first point of interest is located proximate an upcoming transit stop of the public transit line that the mobile device is traveling on.
9. The system of claim 8 wherein the advertising program determines whether a mobile device is traveling on the public transit line by map matching the position of the mobile device to data representing a location of the public transit line.
10. The method of claim 8 wherein the advertising program determines whether a mobile device is traveling on the public transit line by evaluating the speed of travel of the mobile device.
11. The method of claim 8 wherein the advertising program determines whether a mobile device is traveling on the public transit line by evaluating schedule data of the public transit line.
12. The system of claim 8 wherein if the mobile device is not traveling on the public transit line, the advertising program provides a second advertisement message for a second point of interest proximate the position of the mobile device.
13. The system of claim 12 wherein the second advertisement message has an associated advertising area defining a portion of a geographic region, wherein the mobile device is located within the associated advertising area.
14. The system of claim 12 wherein the size of the advertising area depends on a mode of transport of the mobile device.
