I see that everywhere on the highway in the east in the remote area. I think it is a speed detector powered by solar panel. Solar panel is used because it cost more to run electrical wire to a remote place. I think it senses the real time speed and transmit information back to the traffic center. If this is correct, it is used to check vehicle speed to see if any one is speeding so that they can dispatch a police car to track the exact location. Also It can check if there is an incident in that area that cause traffic to slow down.
