  • Service hours per day in the active feed:

Changes from May 01 to May 31

  • Percentage of stop and route IDs that have changed since the previous month.
  • More than 5% being new or dropped is a cause for attention.

Validation errors observed
Error Name Error Description Severity
block_trips_with_overlapping_stop_times Trips within the same block have overlapping stop times, which is not allowed. ERROR
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
duplicate_route_name All routes of the same route_type with the same agency_id should have unique combinations of route_short_name and route_long_name. WARNING
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
stop_too_far_from_trip_shape Per GTFS Best Practices, route alignments (in shapes.txt) should be within 100 meters of stop locations which a trip serves. WARNING
too_fast_travel As implemented in the original Google Python GTFS validator, the calculated speed between stops should not be greater than 150 km/h (42 m/s SI or 93 mph). WARNING
wrong_parent_location_type Value of field location_type of parent found in field parent_station is invalid. Stops, Platforms, Entrance/exit, and generic nodes can only have a Station as a parent. Boarding Area can only have Platform as a parent. Stations cannot have a parent. All other combinations are prohibited. ERROR
