AASHTO: 80% of State Transportation Departments Use Drones
Tuesday, March 27, 2018 | Comments

A survey by the American Association of State Highway and Transportation Officials (AASHTO) found that 35 of 44 responding state departments of transportation (DOTs) — 80 percent — are using unmanned aircraft systems (UAS), or drones, for a wide range of purposes including emergency response.

The March 2018 survey found that 20 state DOTs have incorporated drones into their daily operations. Another 15 state DOTs are in the research phase — testing drones to determine how they can be use. All state DOTs deploying drones follow FAA's Part 107 Rule, or the state DOT has received a public certificate of waiver or authorization (COA) from the FAA to conduct drone operations.

"This is another example of how state DOTs are advancing innovation to improve safety and productivity for the traveling public," said Bud Wright, AASHTO executive director. "Drones are being used to significantly cut the time it takes to gather data, which is leading to major time and cost savings."

All 20 of the state DOTs operating drones on a daily basis are deploying them to gather photos and videos of highway construction projects. In addition to photography, 14 states also reported using them for surveying, 12 for public education and outreach, 10 for bridge inspections, eight for emergency response, six for pavement inspections, five for scientific research, two for daily traffic control and monitoring, and one state DOT used drones to conduct high-mast light pole inspections.

North Carolina was an early adopter of drone technology. In 2013 the state legislature designated the North Carolina Department of Transportation’s (NCDOT) Division of Aviation to be the statewide authority for drone operations. Its UAS program aims to make drone technology available to DOT employees across the state.

"What we're focusing on this spring is trying to get drones into the hands of employees in all 14 division offices in our state," said Basil Yap, manager of NCDOT's UAS Program. "We're training our personnel and providing them with drones to meet their specific needs. By encouraging innovation from the ground up, our employees will help NCDOT discover new applications for drone technology."

Yap said the potential time and cost savings are significant. A joint NCDOT/North Carolina Highway Patrol study in 2017 simulated a head-on crash in a controlled environment. The highway patrol collision reconstruction unit took nearly two hours to collect its data. Pilots using three drones took just 25 minutes to complete the mission. NCDOT says had the simulated crash occurred on I-95, it would have cost an estimated $8,600 in lost productivity for every hour one lane of the interstate was closed. The tally for the traditional investigation $12,900 in lost productivity or just $3,600 using drones-for a $9,300 savings.

"We were blown away by the cost savings that we noticed from this particular research project," said Yap. "By using drones this way motorists, state DOT crews and emergency responders benefit because we're getting them out of harm's way faster by clearing crash scenes quicker."

Of the 35 states deploying drones, 23 have established comprehensive drone policies that cover the acquisition, operation, airspace restrictions, and training and permitting of drones and drone pilots. Twenty-seven of the state DOTs reporting said they were adding full-time staff to operate and maintain their drone fleets.

"We already have local government agencies coming to us and asking for training, and so we've partnered with our community college system to come up with a curriculum to train drone pilots," said Yap. "We're talking about making an economic development decision here because commercial drone package delivery is coming, and state DOTs across the country need to play a role in developing the highways of the sky, especially in urban areas."
