About the November 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 November 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.

Validation errors observed | |||
Error Name | Error Description | Severity | |
decreasing_or_equal_shape_distance | Two consecutive points in shapes.txt should have increasing values for shape_dist_traveled. If the values are equal, this is considered as an error. | ERROR | |
decreasing_or_equal_stop_time_distance | Two consecutive stop times in a trip should have increasing distance. If the values are equal, this is considered as an error. | ERROR | |
feed_expiration_date | At any time, the published GTFS dataset should be valid for at least the next 7 days, and ideally for as long as the operator is confident that the schedule will continue to be operated. If possible, the GTFS dataset should cover at least the next 30 days of service. | WARNING | |
invalid_url | A field contains a malformed URL. | ERROR | |
more_than_one_entity | A file that is expected to have only one row has more than one row. | WARNING | |
number_out_of_range | The values in the given column of the input rows are out of range. | ERROR | |
route_short_and_long_name_equal | Short and long name should not be identical. | WARNING | |
route_short_name_too_long | Short name of a route is too long (more than 12 characters). Note that major trip planning applications start truncating short names after seven characters. | WARNING | |
stop_time_timepoint_without_times | Any record with stop_times.timepoint set to 1 should define a value for stop_times.arrival_time and stop_times.departure_time fields. | WARNING |
