Has RT Feed
This feed includes GTFS-Realtime (GTFS-RT). Realtime data contributes to a better rider experience by letting riders know exactly when their bus or train is coming, as well as detour and trip cancellation info. It also enables Cal-ITP to support transit agencies with analyses such as our California Transit Speed Maps, viewable by clicking the button above. Certain feeds may include RT data but not have a speed map available. To generate a speed map, we require GTFS-RT Vehicle Positions data that matches the rest of the GTFS feed. Additionally, we don't currently generate speed maps for rail service. Please contact us at [email protected] with any questions about GTFS-RT data or suggestions for analysis products.
  • This feed appears to be missing feed_info.txt.
  • Including feed info is important to help data users easily find technical contacts.

About the October Daily Service Level Charts

  • These charts show the total hours of transit service described by the active feed for each day.
  • Since service levels often vary by the day of the week, it is split into three charts for weekdays, Saturdays, and Sundays.
  • Flat lines indicate consistent levels of service throughout the month.
  • Short drops may indicate temporary reduced service, such as for holidays, gaps in feed publishing, or potential inaccuracies.
  • Please reach out to our help desk at [email protected] with any questions.

About the October Identifier Change Charts

  • These charts show the percentage of stop and route IDs that have changed since the previous month.
  • Stop and route IDs are important identifiers for GTFS feed consumers to correctly parse feeds.
  • It is a GTFS Best Practice to keep these consistent between feed versions whenever possible.
  • More than 5% being new or dropped is a cause for attention, especially if there hasn't been a major service or route change.
  • Please reach out to our help desk at [email protected] with any questions.
