No RT Feed
This feed doesn't seem to include 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 useful analysis tools. Please contact us at [email protected] for guidance on how to offer a GTFS-RT feed, or let us know if you're already publishing one that we aren't aware of.

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
stop_without_stop_time A stop in stops.txt is not referenced by any stop_times.stop_id, so it is not used by any trip. 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
