About the September 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 September 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.
