Could Pittsburgh International Airport Soon See Driverless Buses?

Self-driving buses may seem like the product of a science fiction writer’s imagination, but for visitors to Pittsburgh International Airport, they may soon become reality.

Allegheny Airport Authority officials have proposed the Autonomous Vehicle Shuttle Project in a 14-page document detailing the ins and outs of bringing a driverless shuttle bus to the newly renovated airport’s landside terminal. 

The system would modernize the terminal’s transportation system and replace a manually operated shuttle bus fleet with an automated, fixed-guideway Automated Transit Network, according to the report. 

The report details how an autonomous vehicle shuttle system could enhance passenger mobility between remote parking, nearby hotels, the garage and the terminal. It could also provide faster trip times, shorter waiting times and have scheduled and on-demand operational flexibility as well as zero-emission airport circulation and 24/7 all-weather service. 

“This constitutes a fundamental modernization of PIT’s internal circulation system and supports ongoing objectives for improved technology and elevated customer experience,” the report reads.

Initial construction costs include an estimated $30 million for civil infrastructure and an additional $32 million for the autonomous vehicles, although the report claims the benefits of a new driverless system outweigh the cost through the creation of new jobs in construction and site improvements during the building process, as well as permanent roles in system monitoring, fleet maintenance, technology management and administrative functions once the new infrastructure is in place. 

In addition, the proposed shuttles would be battery-electric, as opposed to the current fleet’s diesel- and CNG-powered engines, leading to a reduction in greenhouse gas emissions and further compliance with the ACAA’s net zero commitments and Airport Carbon Accreditation goals.

“Overall, the AV shuttle system represents a step toward a cleaner and more efficient landside transportation system,” the report reads. 

Pittsburgh is already home to a handful of driverless vehicles. Since December 2025, travelers throughout the city may have seen Waymo cabs — the driverless taxis with large LIDAR devices on top — shuttling passengers around the city. While some riders on social media praise the accessibility, safety and novelty of the autonomous vehicles, others worry whether a driverless vehicle can accurately navigate the city’s confusing traffic landscape, including infamous congestion zones like the Fort Pitt and Squirrel Hill tunnels. 

According to the airport’s report, traffic concerns need not be a problem for the proposed shuttles. They would operate on a fixed track designed for magnet-guided movement.

Pennsylvania’s P3 law requires PennDOT to make the detailed project analysis available for public review and comment in advance of any official consideration. A public comment period began on March 15 and runs until April 14. 

Residents are invited to share their thoughts and opinions on the proposed shuttle project through an online comment form, through emailing www.pa.gov/P3comment or through sending mail to PennDOT P3 Office, 400 North St., 6th Floor, Harrisburg PA 17120. All feedback received during the comment period will be collected, summarized and considered prior to any action.
