The present invention relates to the determining of a refresh rate of a dynamic billboard. A system in accordance with an embodiment of the present invention includes: a system for obtaining traffic flow information; a system for determining the refresh rate per minute of the dynamic billboard based on the traffic flow information, wherein the refresh rate is equal to 60 mph/V, wherein V is equal to an average velocity in miles per hour of vehicles passing the dynamic billboard; a system for determining a percent change in the traffic flow information over a predetermined period of time, and comparing the percent change in the traffic flow information to a predetermined threshold value; and a system for changing a display provided by the dynamic bill board in accordance with the refresh rate only if a magnitude of the percent change in the traffic flow information is greater than the predetermined threshold value.

The invention claimed is: 1. A system for determining a refresh rate of a dynamic billboard, comprising: a system for obtaining traffic flow information; a system for determining the refresh rate per minute of the dynamic billboard based on the traffic flow information, wherein the refresh rate is equal to X/V, wherein X is a predetermined velocity, and wherein V is equal to an average velocity of vehicles passing the dynamic billboard; a system for determining a percent change in the traffic flow information over a predetermined period of time, and comparing the percent change in the traffic flow information to a predetermined threshold value; and a system for changing a display provided by the dynamic bill board in accordance with the refresh rate only if a magnitude of the percent change in the traffic flow information is greater than the predetermined threshold value. 2. The system of claim 1, wherein the dynamic billboard is selected from the group consisting of a mechanical billboard and a digital billboard. 3. The system of claim 1, wherein the display comprises an advertisement. 4. The system of claim 1, further comprising: a system for updating the refresh rate of the dynamic billboard based on current traffic flow information. 5. The system of claim 1, further comprising: a system for increasing the refresh rate of the dynamic billboard when traffic slows down in a vicinity of the dynamic billboard. 6. The system of claim 1, further comprising: a system for decreasing the refresh rate of the dynamic billboard when traffic speeds up in a vicinity of the dynamic billboard. 7. The system of claim 1, wherein the system for obtaining traffic flow information and determining the refresh rate periodically obtains traffic flow information and the refresh rate. 8. A computer program product stored on a computer readable storage medium, which when executed, determines a refresh rate of a dynamic billboard, the computer readable storage medium comprising program code for: obtaining traffic flow information; determining the refresh rate per minute of the dynamic billboard based on the traffic flow information, wherein the refresh rate is equal to X/V, wherein X is a predetermined velocity, and wherein V is equal to an average velocity of vehicles passing the dynamic billboard; determining a percent change in the traffic flow information over a predetermined period of time, and comparing the percent change in the traffic flow information to a predetermined threshold value; and changing a display provided by the dynamic bill board in accordance with the refresh rate only if a magnitude of the percent change in the traffic flow information is greater than the predetermined threshold value. 9. The program product of claim 8, wherein the dynamic billboard is selected from the group consisting of a mechanical billboard and a digital billboard. 10. The program product of claim 8, wherein the display comprises an advertisement. 11. The program product of claim 8, further comprising program code for: updating the refresh rate of the dynamic billboard based on current traffic flow information. 12. The program product of claim 8, further comprising program code for: increasing the refresh rate of the dynamic billboard when traffic slows down in a vicinity of the dynamic billboard. 13. The program product of claim 8, further comprising program code for: decreasing the refresh rate of the dynamic billboard when traffic speeds up in a vicinity of the dynamic billboard. 14. The program product of claim 8, wherein the program code for obtaining traffic flow information and determining the refresh rate periodically obtains traffic flow information and the refresh rate. 15. A method for determining a refresh rate of a dynamic billboard, comprising: obtaining traffic flow information; determining the refresh rate per minute of the dynamic billboard based on the traffic flow information, wherein the refresh rate is equal to X/V, wherein X is a predetermined velocity, and wherein V is equal to an average velocity of vehicles passing the dynamic billboard; determining a percent change in the traffic flow information over a predetermined period of time, and comparing the percent change in the traffic flow information to a predetermined threshold value; and changing a display provided by the dynamic bill board in accordance with the refresh rate only if a magnitude of the percent change in the traffic flow information is greater than the predetermined threshold value. 16. The method of claim 15, wherein the dynamic billboard is selected from the group consisting of a mechanical billboard and a digital billboard. 17. The method of claim 15, further comprising: updating the refresh rate of the dynamic billboard based on current traffic flow information. 18. The method of claim 15, further comprising: increasing the refresh rate of the dynamic billboard when traffic slows down in a vicinity of the dynamic billboard; or decreasing the refresh rate of the dynamic billboard when traffic speeds up in a vicinity of the dynamic billboard. 19. The method of claim 15, wherein obtaining traffic flow information and determining the refresh rate are performed periodically.
