State DOTs Expand Drone Programs, Transforming Infrastructure Management

Алабама‘s Департамент транспорта (ALDOT) has launched a formal drone program that signals the growing maturation of unmanned aerial systems (UAS) deployment across state transportation agencies. The initiative, which places dedicated personnel in charge of drone operations, represents a shift from experimental projects to systematic integration of UAS technology into core infrastructure management operations.

Long-time agency veteran John D’arville как сообщается, heads the program as UAS Administrator, working alongside UAS Manager Jonathan Woodham to oversee operations that span construction monitoring, infrastructure inspection, and environmental assessment. Their approach emphasizes both operational efficiency and regulatory compliance, requiring two-person crews to maintain visual line of sight during all flights.

The program’s impact on bridge inspection illustrates the practical benefits driving drone adoption. Using specialized mapping drones capable of capturing imagery within 6 inches of structures, ALDOT can now generate detailed 3D models for remote inspection. This capability eliminates up to four hours of travel time for inspectors examining bridges in remote locations, while maintaining safety standards and reducing traffic disruption.

Environmental considerations also factor prominently in the program’s justification. D’arville points to a recent wetland survey where drone deployment dramatically reduced ground impact: “We flew around an 800-acre wetland irrigation area for two hours versus stomping around it for days like we used to have to do.”

The Alabama initiative reflects a broader trend across state transportation agencies. In Аляска, the Department of Transportation and Public Facilities has integrated drones into its avalanche mitigation strategy, while Аризона DOT employs UAS for detailed inspection of storm runoff pump stations throughout the Phoenix metropolitan area.

Perhaps most innovative is Washington State DOT’s deployment of drones for maintenance operations, including a pioneering program using UAS platforms for graffiti removal in hard-to-reach locations. This application demonstrates how agencies are moving beyond simple inspection tasks to active infrastructure maintenance.

Миннесота DOT has focused on using drones for comprehensive aerial mapping, creating detailed records of transportation infrastructure and right-of-way conditions that support future planning and design work .

Джорджия‘s program takes yet another approach, testing “Drone as First Responder” (DFR) capabilities along the I-85 corridor since August 2023. This application suggests how DOT drone programs might eventually expand beyond infrastructure management into real-time traffic and incident response.

These developments indicate that state transportation agencies are rapidly moving beyond viewing drones as merely supplementary tools. Instead, UAS technology is becoming integral to core operations, promising improved efficiency, enhanced safety, and reduced environmental impact across the transportation infrastructure sector.

The success of these programs may accelerate adoption across other state agencies, particularly as the Federal Aviation Administration continues to evolve regulations around beyond visual line of sight (BVLOS) operations and other advanced drone applications. For state DOTs, the question appears to be not whether to implement drone programs, but how quickly they can scale them.
