TigerTransit
TigerTransit is the Princeton University shuttle bus service in and around its campus in Princeton, New Jersey and other nearby areas of Mercer County. TigerTransit operates nine routes within the campus and around the city of Princeton. WeDriveU operates the service.
Routes
All TigerTransit routes are free of charge and open to the public. Main routes only operate on during the daytime on weekdays, with two routes providing daily late night service and three routes providing weekend-only service. The Princeton Junction branch of Route 4 essentially functions as an alternative to the Princeton Branch. The Weekend Shopper route combines service around much of the Princeton campus with service along US-1 to shopping centers in Princeton, West Windsor, and Lawrenceville.Route list
