The New York Department of Environmental Conservation will use two drones this weekend to provide real-time video of traffic and monitor traffic and parking conditions at the New York State Fair in Geddes, N.Y.

According to the website newyorkupstate.com, the fair often attracts more than 100,000 visitors per day on weekends, and the drones will alert travelers to traffic changes, parking lots that are nearing capacity or accidents, by sending alerts to electronic message signs along nearby highways.
