UA’s electric bus fleet connects research to transit operations

TUSCALOOSA, Ala. - The University of Alabama is putting research into service with the launch of its new electric bus fleet.

Funded through a federal grant secured by UA researchers and campus partners, the buses provide quieter, energy-efficient transit while creating a real-world research platform for evolving transportation technologies.

While the buses will serve riders across campus, the impact will reach even further. The data generated through these buses is already supporting research into vehicle-to-grid technology and energy systems that will benefit the wider region.

"This is a project that offers emission-free transportation and advanced mobility technologies for the community," said Dr. Bharat Balasubramanian, executive director of the Center for Advanced Vehicle Technologies and chief mobility research and development officer at the Alabama Transportation Institute. "At the same time, it creates a living laboratory where students and faculty can study electric mobility in real-world operations."

The University was among a small number of universities to receive federal funding typically awarded to public transit agencies. According to Balasubramanian, UA operates one of the largest transit systems in Alabama, with nearly 50 buses in its fleet, providing free public transportation on the UA campus and to some nearby locations.

A Classroom on Wheels

UA's new electric buses will operate daily while simultaneously generating data for research and education.

Through a collaboration with bus manufacturer New Flyer, researchers have access to detailed operating data from the vehicles, including battery performance, energy consumption, charging behavior and vehicle systems.

That information will allow faculty and students to study questions facing transit agencies across the country.

Researchers will study how Alabama's summer heat affects battery range and air conditioning demand, along with charging strategies, route optimization and long-term vehicle performance. Future student projects will explore ways to improve efficiency in extreme weather.

"There are all sorts of operational questions we can now answer with data these buses are generating," Balasubramanian said. "How much energy does a bus use on real routes? What happens on extremely hot or cold days? How do we optimize range and efficiency? Those are questions that can only be answered through real-world experience."

The buses are also supporting additional federally funded research involving C-V2X, a wireless platform that lets vehicles communicate with traffic signals, energy systems, vehicle-to-grid technologies and campus energy management. Researchers are exploring ways electric buses could one day help stabilize electrical grids and integrate with renewable energy resources.

Bringing Research and Operations Together

Campus transportation leaders say one of the project's most important outcomes is the collaboration it has created between researchers and the operational teams responsible for moving thousands of riders each day.

"I like how collaborative it is," said Chris D'Esposito, assistant vice president of enterprise services. "It involves the research side and the operations side. They brought the bus into real-world operations where we're moving students every day while researchers learn from how the technology performs."

D'Esposito said the partnership allows the campus operations teams to draw on expertise already available at the University, giving students opportunities to engage directly with emerging transportation technologies and solve real operational challenges.

The Road Ahead

Since entering service, the buses have attracted attention across campus for their distinctive appearance and nearly silent operation.

"The first thing people notice is how quiet they are," Balasubramanian said. "There is no diesel noise. The ride is incredibly smooth, and the air conditioning stays at a constant level."

For Balasubramanian, the launch represents the beginning of a much larger vision.

"My definition of success is the day The University of Alabama operates an entirely zero-emission transit fleet," he said. "The long-term goal is to create a transportation system that benefits not only the campus but the entire region with safe and clean mobility."
