Where do the time predictions come from in OneBusAway?

King County Metro

Pierce Transit

GPS-based tracking system

Other Agencies

Other agencies use time predictions based on schedule data they provide to OneBusAway.

My results show a bunch of colors. What do the colored numbers mean?

  • Green - means the bus is on time
  • Blue - means the bus is late
  • Red - means the bus is early
  • Black - means no real-time info is available (this is the scheduled arrival time)
