Eastern Sierra Transit Authority  ·  December 2022

This is a monthly report, generated by the California Integrated Travel Project (Cal-ITP), summarizing issues discovered by MobilityData’s GTFS Validator. This report is available for viewing by the general public to support continuous improvement of GTFS data and the experience of transit passengers.

Has RT Feed
This feed includes 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 analyses such as our California Transit Speed Maps, viewable by clicking the button above. Certain feeds may include RT data but not have a speed map available. To generate a speed map, we require GTFS-RT Vehicle Positions data that matches the rest of the GTFS feed. Additionally, we don't currently generate speed maps for rail service. Please contact us at [email protected] with any questions about GTFS-RT data or suggestions for analysis products.

About the December 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 December 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.

Error Name Error Description Severity
unknown_file A file is unknown. INFO
unknown_column A column is unknown. INFO
fast_travel_between_far_stops A transit vehicle moves too fast between far consecutive stops (more than in 10 km apart). WARNING
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
fast_travel_between_consecutive_stops A transit vehicle moves too fast between two consecutive stops. The speed threshold depends on route type. WARNING
stop_time_timepoint_without_times Any records with stop_times.timepoint set to 1 must define a value for stop_times.arrival_time and stop_times.departure_time fields. 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
