2. The method of claim 1, wherein the location information comprises the location of the first wireless device.

3. The method of claim 1, wherein the identification information comprises an identifier sufficient to uniquely identify the first wireless device within a geographic region.

4. The method of claim 1, further comprising receiving second wireless device location and second wireless device identification information from the second wireless device.

5. The method of claim 4, further comprising calculating a second wireless device speed of the second wireless device.

6. The method of claim 5, further comprising transmitting second wireless device data selected from the group consisting of second wireless device speed, second wireless device location, and second wireless device identification of the second wireless device to the first wireless device.

7. The method of claim 1, further comprising receiving traffic information from a traffic center.

8. The method of claim 7, further comprising sending the received traffic information to the first wireless device.

9. The method of claim 1, further comprising sending data selected from the group consisting of speed, location, and identification information of the first wireless device to a user.

10. The method of claim 1, wherein calculating a speed of the wireless device comprises:

receiving a second location from the first wireless device; and

calculating speed as the differential distance between the location and the second location of the first wireless device, divided by the differential time between when the location and the second location was received from the first wireless device.

11. A system for distributing traffic information, comprising:

a memory; and

a processor coupled to the memory, wherein the processor has the capability of;

receiving location information and identification information from a first wireless device;

calculating speed of the first wireless device; and

transmitting one or more of the speed, location and identification of the first wireless device to a second wireless device.

12. The system of claim 11, wherein the location information comprises the location of the first wireless device.

13. The system of claim 11, wherein the identification information comprises an identifier sufficient to uniquely identify the first wireless device within a geographic region.

14. The system of claim 11, wherein the processor is further operable to receive a second wireless device location and a second wireless device identification information from the second wireless device.

15. The system of claim 14, wherein the processor is further capable of calculating a second wireless device speed of the second wireless device.

16. The system of claim 15, wherein the processor is further capable of transmitting a second wireless device data selected from the group consisting of second wireless device speed, second wireless device location, and second wireless device identification of the second wireless device to the first wireless device.

17. The system of claim 11, wherein the processor is further capable of receiving traffic information from a traffic center.

18. The system of claim 17, wherein the processor is further capable of sending the received traffic information to the first wireless device.

19. The system of claim 11, wherein the processor is further capable of sending data selected from the group consisting of speed, location, and identification information of the first wireless device to a user.

20. The system of claim 11, wherein the processor is further capable of:

receiving a second location from the first wireless device; and

calculating speed as the differential distance between the location and the second location of the first wireless device, divided by the differential time between when the location and the second location was received from the first wireless device.

21. A method of distributing traffic information, comprising:

receiving speed and location information from a first wireless device; and

transmitting the speed and location of the first wireless device to a second wireless device.

22. The method of claim 21, wherein the location information comprises the location of the first wireless device.

23. The method of claim 21, further comprising receiving second wireless device location and second wireless device speed information from the second wireless device.

24. The method of claim 23, further comprising transmitting second wireless device speed and second wireless device location information to the first wireless device.

25. The method of claim 21, further comprising receiving traffic information from a traffic center.

26. The method of claim 25, further comprising sending the received traffic information to the first wireless device.

27. The method of claim 21, further comprising sending speed and location information of the first wireless device to a user.
