The university is developing a comprehensive master plan that partially aims to reduce the number of single- ccupant vehicles on campus. A comprehensive shuttle bus program includes vehicles that run on compressed natural gas (CNG), waste vegetable oil, and biodiesel. The motor pool includes such alternative technologies as CNG, hybrid, flex-fuel, and biodiesel. Students, faculty, and staff ride public transportation free through the Utah Transit Authority Education Pass Program. The university has experienced increased mass transit ridership recently due to expanded public transportation.
