CVG and UC put AI to work to shorten airport lines
UC engineering student's algorithm helps airport predict crowding
The University of Cincinnati is teaming up with Cincinnati/Northern Kentucky International Airport to address crowding.
UC College of Engineering and Applied Science doctoral student Javier Viaña used airport technology that identifies the number of people entering the terminals to build a custom algorithm that can help the airport predict surges of travelers in 15-minute increments.
This information could help the Transportation Security Administration anticipate when to open new lines, Viaña said.

“The main objective of this work is to improve the passenger experience and inform operational decision-making at the airport," said Candace McGraw, CEO of Cincinnati/Northern Kentucky International Airport.
“The modelling done by Javier provides the airport and our business partners reliable data to prepare our operations based on passenger arrival predictions, potentially reducing crowding and wait times along the travel journey from parking and check-in to security screening and concessions.”
UC used an artificial intelligence based on fuzzy logic, a type of computer decision making that relies on degrees of truth rather than a binary true-false dichotomy. As a result, the algorithm is explainable and transparent, Viaña said.
“A lot of AI algorithms we use are opaque. They’re a black box,” he said. “Neural networks are difficult to understand from a human perspective. We understand the mathematical logic behind them, but they’re difficult to visualize. And that lack of transparency can create suspicion.”
This collaboration led to the Nov. 17 signing of a three-year memorandum of understanding between UC and the Kenton County Airport Board to collaborate on research and technology projects. Among other projects, UC is studying driverless vehicles, autonomous drones and autonomous robots that might prove useful for future applications at the airport.
Airports already know how many passengers to expect from flight reservations. But Viaña said that doesn’t tell them how many people to expect in a terminal at any given time.
“There’s a big difference between the flight schedule and the actual flow of people,” he said. “You might be able to say 10,000 people will be taking off at 10 a.m. But they don’t show up at 10 a.m. Some might show up at 8:45 or 9:20.”
His algorithm more precisely predicts how many people will filter through check-in and security in 15-minute intervals, Viaña said.
“It’s an exciting project. We’ve been getting good results,” Viaña said.

UC’s work is funded in part through a grant from the Airport Cooperative Research Program, an industry-driven network that develops near-term practical solutions to airport challenges.
“Everyone else who has gotten this grant award has gone on to great success, so there is a lot of pressure,” Viaña said. “But it’s a nice feeling to be counted among them.”
Knowing more about whom is in the building at any time also could help advertisers in the airport target particular groups of travelers on digital billboards, Viaña said.
“If you know at some point in the airport you’ll have passengers traveling to Hawaii, you could make better advertisements targeting those passengers based on their destinations,” he said.
Viaña and the airport plan to offer UC’s predictive algorithm to other airports interested in improving their efficiency and their passengers’ travel experience.
