CRTM — Red de Autobuses Urbanos (Madrid regional urban bus)

Stop time with arrival before previous departure time (flagged by the MobilityData validator).

See the linked rule for what this affects.

Fix: Review the rule documentation for 'stop_time_with_arrival_before_previous_departure_time' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

Equal shape distance diff coordinates (flagged by the MobilityData validator).

See the linked rule for what this affects.

Fix: Review the rule documentation for 'equal_shape_distance_diff_coordinates' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

Some rider-facing names are in ALL CAPS or all lowercase.

ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.

Fix: Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE'). (Often a bulk fix in your scheduling software.)

15490 of 15490 trips don't say whether the vehicle is wheelchair accessible.

Even with accessible stops, riders need to know the bus itself can take them.

Fix: Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip. (A default or per-trip field in your export.)

Some route lines list the same point twice in a row.

Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.

Fix: Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt. (Usually one export setting.)

Some stops exist in the feed but no trip ever stops at them.

Riders may walk to a stop where no bus is scheduled to arrive.

Fix: Remove retired stops from the export, or add them back to the trips that should serve them. (A review pass in your scheduling software.)

Finding code: stop_without_stop_time · Read the fix guide for stop_without_stop_time · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

2452 of 8406 stops don't say whether a wheelchair user can board there.

Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.

Fix: Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. (A column in stops.txt; your scheduling software likely has it.)

Some scheduled trips move faster between stops than a bus can.

Usually a typo'd stop time; riders get arrival times no bus can meet.

Fix: Check the flagged stop times for transposed minutes. (A few minutes per flagged trip.)

Finding code: fast_travel_between_consecutive_stops · Read the fix guide for fast_travel_between_consecutive_stops · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

Between two distant stops, the times imply a speed no bus reaches.

A rider gets a trip plan that cannot happen. Live systems then report delays that are not real.

Fix: Check the two stop times for a wrong digit first. Then check whether a stop sits at the wrong coordinates, or a stop between them is missing. (Minutes per flagged trip once you open it.)

Equal shape distance diff coordinates distance below threshold (flagged by the MobilityData validator).

See the linked rule for what this affects.

Fix: Review the rule documentation for 'equal_shape_distance_diff_coordinates_distance_below_threshold' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

Some files leave out fields that GTFS asks for but does not require.

Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.

Fix: Review the flagged fields and fill in the ones your riders would use. (A field at a time; not urgent.)

Finding code: missing_recommended_field · Read the fix guide for missing_recommended_field · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

Some stops sit far from the route line they belong to.

Trip planners may draw the bus route through the wrong streets or point riders to the wrong corner.

Fix: Check the flagged stops' coordinates and the route shape in your scheduling software; re-snap whichever is misplaced. (A few minutes per flagged stop.)

Finding code: stop_too_far_from_shape · Read the fix guide for stop_too_far_from_shape · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

feed_info.txt lists no contact email and no contact URL.

Without a contact, apps like Google Maps can't reach you when they find a problem in the feed.

Fix: Add feed_contact_email or feed_contact_url to feed_info.txt. (One field, set once in export settings.)

Finding code: missing_feed_contact_email_and_url · Read the fix guide for missing_feed_contact_email_and_url · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

Some route long names repeat the route's short name inside them.

Apps show both names together, so riders see the number twice, like '5 5 Downtown'.

Fix: Drop the short name from route_long_name and keep the long name descriptive, like 'Downtown via 5th Ave'. (One field per flagged route.)

Finding code: route_long_name_contains_short_name · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

On some trips the stops fall along the route line in a different order than the schedule lists.

Trip planners can draw the bus doubling back or skipping ahead, which confuses riders reading the map.

Fix: Check the stop order and the shape direction in your scheduling software; the shape is often drawn backwards. (A few minutes per flagged trip.)

Finding code: stops_match_shape_out_of_order · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

More than one entity (flagged by the MobilityData validator).

See the linked rule for what this affects.

Fix: Review the rule documentation for 'more_than_one_entity' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

Finding code: more_than_one_entity · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

feed_info.txt is missing its start/end dates

Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.

Fix: Add feed_info.txt with feed_start_date and feed_end_date to your export. (Two fields, set once in export settings.)

Finding code: scorecard_missing_feed_info_dates · Read the fix guide for scorecard_missing_feed_info_dates · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

The feed contains no fare information.

Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

Fix: Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead. (A small file for most flat-fare systems.)

Finding code: scorecard_no_fare_data · Read the fix guide for scorecard_no_fare_data · See GTFS Best Practices (opens GTFS Best Practices on an external site)

This feed models stations or entrances but has no pathways.txt.

Trip planners can't guide riders through the station, and there is no step-free route information for wheelchair users.

Fix: Add pathways.txt to link entrances, platforms, and elevators. Give each one a level. (Worth it for multi-level or large stations; flat stops don't need it.)

About 8396 stop names are written in ALL CAPS.

Mixed-case names are easier to read in apps and are read more naturally by screen readers.

Fix: Rename stops to mixed case where the language has letter case (for example, 'Central Station'). (Often a bulk fix in your scheduling software.)

feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).

App makers and state data programs have nobody to email when they spot a problem. Small errors then sit in the feed for months.

Fix: Add feed_contact_email to feed_info.txt. (One field.)
