About the April 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 April 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 April 01 to April 30
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.
