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.

| Validation errors observed | |||
| Error Name | Error Description | Severity | |
| unknown_file | A file is unknown. | INFO | |
| unknown_column | A column is unknown. | INFO | |
| foreign_key_violation | A foreign key references the primary key of another file. A foreign key violation means that the foreign key referenced from a given row (the child file) cannot be found in the corresponding file (the parent file). The Foreign keys are defined in the specification under "Type" for each file. | ERROR | |
| duplicate_key | The values of the given key and rows are duplicates. | ERROR | |
| missing_recommended_field | The given field has no value in some input row, even though values are recommended. | WARNING | |
| stop_too_far_from_shape | Per GTFS Best Practices, route alignments (in shapes.txt) should be within 100 meters of stop locations which a trip serves. | WARNING | |
| stop_too_far_from_shape_using_user_distance | A stop time entry that is a large distance away from the location of the shape in shapes.txt as defined by shape_dist_traveled values. | WARNING | |
| duplicate_fare_rule_zone_id_fields | The combination of fare_rules.route_id, fare_rules.origin_id, fare_rules.contains_id and fare_rules.destination_id fields should be unique in GTFS file fare_rules.txt. | ERROR | |
| invalid_currency_amount | A currency amount field has a value that does not match the format (e.g. expected number of decimal places) of its corresponding currency code field. The number of decimal places is specified by ISO 4217. | ERROR | |
| stop_without_zone_id | If fare_rules.txt is provided, and fare_rules.txt uses at least one column among origin_id, destination_id, and contains_id, then all stops and platforms (location_type = 0) must have stops.zone_id assigned. | ERROR | |
| fare_transfer_rule_with_forbidden_transfer_count | A row from GTFS file fare_transfer_rules.txt has from_leg_group_id not equal to to_leg_group_id, but has transfer_count specified. Per the spec, transfer_count is forbidden if the two leg group ids are not equal. | ERROR | |
| equal_shape_distance_diff_coordinates | When sorted by shape.shape_pt_sequence, the values for shape_dist_traveled must increase along a shape. Two consecutive points with equal values for shape_dist_traveled and different coordinates indicate an error. | ERROR | |
| equal_shape_distance_same_coordinates | When sorted by shape.shape_pt_sequence, the values for shape_dist_traveled must increase along a shape. Two consecutive points with equal values for shape_dist_traveled and the same coordinates indicate a duplicative shape point. | WARNING | |
