More state transportation agencies are using aerial drones, and overall commercial use of the devices is expected to continue to climb, though not as dramatically as predicted in 2017, recent reports say.
Results of an American Association of State Highway and Transportation Officials study, released on March 27, show that 20 state departments of transportation have made use of unmanned aerial systems (UAS), as drones are more formally known. AASHTO said another 15 DOTs are studying how they might employ the aerial technology.
