Frequently asked questions
How often does UTA Tracker refresh live transit data?
UTA Tracker refreshes GTFS-RT vehicle, trip update, and alert data continuously and revalidates the live snapshot on a short server interval so vehicle positions, delays, and stop projections stay current without a full page reload.
Does UTA Tracker use official Utah Transit Authority data?
Yes. UTA Tracker uses Utah Transit Authority GTFS static data and GTFS-realtime feeds for route definitions, stops, scheduled times, vehicle positions, trip updates, and service alerts.
Can I view UTA timetables for a future date?
Yes. Route and stop timetable views can be derived from the published UTA schedule for future dates so you can inspect planned service beyond the current day.
What UTA services can I track here?
UTA Tracker covers UTA bus routes, TRAX light rail, FrontRunner commuter rail, the S-Line streetcar, and the BRT services UVX and OGX.
Why can a scheduled time differ from a live projected time?
The scheduled time comes from GTFS static timetables, while the projected time is adjusted from GTFS-realtime trip updates or server-side estimation based on the active vehicle position and trip progress.
Is UTA Tracker the official Utah Transit Authority website?
No. UTA Tracker is a third-party tracker built on public transit data. For official agency notices and rider information, consult Utah Transit Authority directly.
