To get around the University area, there is the OCCT bus
Off Campus College Transport (OCCT) is the student run transportation service for Binghamton University students, faculty and staff. OCCT offers safe, reliable, convenient, consistent and courteous transportation around the Binghamton University community.
Simply show your Binghamton University ID card and ride. OCCT routes go to the University Downtown Center (UDC), Innovative Technology Center (ITC), Walmart, Wegmans, Target, Oakdale Mall, Downtown Binghamton, NYSEG Stadium and many more destinations. OCCT also has campus shuttles that transport students, faculty and staff around campus. The campus shuttles are green and run on a continuous loop of campus Monday - Friday. On weekends, the campus shuttle is performed by a blue bus and runs on a set schedule.
