COVID 19 UPDATES: In accordance with NJ Governor Executive Orders for transit services and Princeton’s COVID-19 campus policies: All passengers will be required to wear a face covering unless approved for a medical accommodation (see EHS face covering policy) and maintain social distancing as much as possible. Frequent hand washing is highly recommended. All boarding and exiting are from the rear of the bus. TigerTransit ridership is being monitored during peak trips for crowding, and drivers will enforce 50% capacity limits. Extra buses will be added, if required, to accommodate high-demand routes like the Weekend Shopper. TigerTransit buses undergo more frequent cleaning/disinfecting. TigerTransit drivers are enrolled in the University's weekly COVID testing program.


Princeton University’s TigerTransit shuttle system operates on a fixed route schedule, providing safe, convenient and reliable transportation throughout the Princeton campus and surrounding community. There are TigerTransit stops located at most major academic and administrative buildings, commuter parking lots, and housing facilities. The system is free and open to the public, except for late-night on-demand service and service from Princeton Junction, when passengers must present a valid University ID to board.

Shuttle operations will be limited or suspended during University holidays and, rarely, during severe weather events. Check the TPS homepage for announcements regarding any major disruption to scheduled service.

TigerTransit routes and timetables are subject to change throughout the year. Check the TPS homepage and Twitter feed for news about changes.

Tiger Transit Service Design Guidelines
  • The purpose of TigerTransit is primarily to connect University buildings and facilities to one another, to parking and to public transit, at the times when students, faculty, and staff must travel among them.
  • Most routes will be expected to attract 20 boardings per service hour. This is because they are designed to:
    • Offer high frequencies where large numbers of people need to travel over distances too far to walk.
    • Provide for direct, non-circuitous travel among major destinations.
    • Serve two-way demand and overlapping markets with the same route when possible
  • Some routes will be needed even if they do not attract 20 boardings per service hour, in order to:
    • Connect students to classes that are not easily reachable by walking or bicycling.
    • Serve those who have difficulty walking or riding fixed-route transit.
    • Support student life by providing access to shopping and services.
  • Services that meet these guidelines may require people to walk up to 10 minutes from a University building to reach a TigerTransit stop.
  • For University buildings which are costly to reach with transit or where very few people can be expected to ride, the University will find other more cost-effective ways to help people commute and move around throughout the day.
