Georgia Tech Studies UAS for Monitoring Highway Traffic

Researchers at Georgia Tech are studying the potential use of UAS to monitor I-285 and other congested highways for backups or help with accident investigations to clear roads faster.The Tech study is part of a yearlong project exploring how UAS might help the Georgia Department of Transportation with its day-to-day mission, even though widespread use of them is still years away. GDOT is funding the $75,000 study with a combination of federal research funds and state funds.

“We can already see so many applications that would make things so much better for all of us,” said Georgia Tech assistant professor Javier Irizarry, a lead researcher in the study.

Atlanta traffic congestion is the seventh-worst in the nation, according to the Texas A&M Transportation Institute’s Urban Mobility report.

Irizarry thinks that UAS can improve the accuracy and timeliness of GDOT’s online Navigator map of highway congestion. Existing stationary cameras have a limited field of vision, he said, and sometimes “traffic managers can see backup, but they cannot see what the cause is.”

On the Navigator map or on dynamic highway signs, “that data could be more precise. … It could be more real-time.”

Georgene Geary, a GDOT research engineer, said she hopes that UAS might also be able to help with clearing accidents faster to reduce backups.

The study will also explore how they could be used in other GDOT areas ranging from construction to airports.

Geary hopes that UAS might help also with bridge inspections. Workers today get into “snooper trucks” that hang over the side of the bridge to inspect the underside of tall bridges. But an unmanned aircraft might be able to do the job more quickly, safely and at lower expense, she said.

Irizarry and his partner in the study, Eric Johnson, an associate professor of avionics integration at Georgia Tech’s School of Aerospace Engineering, are interviewing GDOT employees and plan to do a cost-benefit analysis of UAS usage at GDOT.

Other states such as Utah have done different tests of the aircraft for highway surveying and other uses.

Plans are to share the results of the Georgia Tech study with other state transportation departments, “so it may end up having influence beyond Georgia as well,” Johnson said.

The Association for Unmanned Vehicle Systems International estimates the unmanned aircraft industry will create more than 70,000 new jobs in the first three years after the FAA completes its guidelines using drones in U.S. airspace in 2015.

“It’s coming — it’s not a question of if, it’s a question of when,” said Steve Justice, director of Georgia’s Center of Innovation for Aerospace.

The FAA says unmanned aircraft systems can come in “a variety of shapes and sizes, and serve diverse purposes.” The aircraft can be “smaller than a radio-controlled model airplane” or have a wingspan the size of a Boeing 737, the agency said.

Justice thinks many of the UAS will probably fly at low altitudes — perhaps 300 to 400 feet — to inspect things such as crops, roadways and construction projects, and will be relatively small. “Most people would not even notice that they’re there,” Justice said.

The FAA plans to propose procedures, policies and standards for users of small unmanned aircraft — defined as under 55 pounds — later this year.

Meanwhile, Georgia is competing to be selected as one of six test sites for unmanned aircraft systems. An FAA decision is expected by the end of the year. A test site could be used to test potential capabilities of the UAS for GDOT.

As GDOT’s study proceeds, Geary said if the use of UAS is feasible, “we may go through another phase and actually test it out, do a pilot.” She envisions GDOT working with a consultant to use the aircraft, rather than the department managing its own fleet.

The reaction of GDOT employees to the possibility of using UAS in their jobs has varied, Geary said. But by studying the issue before the widespread use of of the aircraft comes, “that gives people time to think about it.”
