Monthly GTFS Quality Report
San Joaquin Regional Transit District  ·  March 2023

This is a monthly report generated by the California Integrated Travel Project (Cal-ITP) and Caltrans. It summarizes progress towards the California Transit Data Guidelines, in addition to providing a snapshot of transit service characteristics such as service hours. This report is available for viewing by the general public to support continuous improvement of GTFS data and the experience of transit passengers.

Current GTFS Feed Info

Feed End Date
Days With No Service
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 March 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 March 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.

Changes from March 01 to March 31

Error Name Error Description Severity
missing_recommended_field The given field has no value in some input row, even though values are recommended. 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_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
stops_match_shape_out_of_order Two stop entries in stop_times.txt are different than their arrival-departure order as defined by the shape in the shapes.txt file. 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
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
