This feed doesn't seem to include 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 useful analysis tools. Please contact us at hello@calitp.org for guidance on how to offer a GTFS-RT feed, or let us know if you're already publishing one that we aren't aware of.

About the December 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 hello@calitp.org with any questions.

About the December 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 hello@calitp.org with any questions.

Consistency with the California Transit Data Guidelines

The following checks measure adherence to the GTFS Compliance (Schedule) and GTFS Compliance (Realtime) portions of the California Transit Data Guidelines.

The following symbols are used to denote each check's outcome on the given date:

  • Pass
  • Fail
  • Not applicable/data unavailable

Checks marked with an asterisk (*) are periodically performed manually. We can update these on request, so let us know if one of them looks off. For agencies participating in a regional GTFS feed, such as the Bay Area 511 feed, the "No errors in MobilityData GTFS Schedule Validator" check may show a Fail if there are any validation errors present in the regional feed, even if the single-agency feed contains no errors. We believe this is unlikely to impact the rider experience.
