Monthly GTFS Quality Report
City of Beaumont  ·  October 2023

This is a monthly report generated by the California Integrated Travel Project (Cal-ITP) and Caltrans. It summarizes progress towards the California Transit Data Guidelines, in addition to providing a snapshot of transit service characteristics such as service hours. This report is available for viewing by the general public to support continuous improvement of GTFS data and the experience of transit passengers.

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 below. 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.

About the Realtime Completeness Charts

  • These charts show the percentage of Scheduled Trips with at least one Trip Update or Vehicle Position message assigned to that trip.
  • High percentages with flat lines are best and indicate large amounts of realtime information for customers.
  • Short drops may indicate schedule inaccuracies, missed runs (buses not on schedule), or hardware failures.

Trip Updates Completeness by Day

Vehicle Positions Completeness by Day

About the Median Message Age Charts

  • These charts show the daily average age of the median message for Trip Updates and Vehicle Position messages over time.
  • The charts provides insights into how long it takes to get messages from the vehicles to riders. Lower latencies are better.
  • Higher latencies may indicate outdated hardware or technical failures.

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.

Changes from October 01 to October 31


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.
