Research In Motion recently filed two patent applications for special digital roadside ads.

Engadget points us to an interesting concept by Research In Motion for a dynamic billboard that can change its message based on fluctuating traffic conditions. The company recently filed two patent applications for the system, which would use sensors to detect when traffic was building up, and present a more content-rich ad. When vehicles are passing quickly, standard only information such as the exit number and name of a gas station or restaurant would be displayed.
