Campus Area Bus Service (CABS) is a free public transportation system at the Ohio State University's Columbus campus. The system consists of five bus routes that connect various points of Ohio State's campus, and the immediate off-campus area. The system connects with the Central Ohio Transit Authority's bus routes at several points.
The system is one of the largest campus transit systems in the United States. Ridership has grown from 4 million passengers in 2003 to an estimated 5 million passengers in 2015.
