In September 2006, RTA partnered with the University of California, Riverside (UCR) to provide their students with an all-access bus pass. UC Riverside students get free rides on all fixed-route and CommuterLink buses by swiping their valid university identification cards through any RTA bus farebox when they board. The program, called U-Pass, is designed to help ease traffic congestion around campus, reduce parking problems and encourage ride-sharing. Additionally, RTA operates a trolley service called the Crest Cruiser that is free to UCR students and travels around the university to off-campus housing and retail outlets. Students of La Sierra University have also benefited from U-Pass since January 2009, and California Baptist University joined the program in August 2009.
