A data-quality and completeness lens to help an agency improve its GTFS feed. Not an official compliance determination from any transit program. New to this? How to read your scorecard. Interactive view of this scorecard. Rubric v1.3, validator 8.0.1.

Checked for changes 55 minutes ago; last changed 55 minutes ago.

Measured 3 of 4 score categories from the feed URL on file (publisher not verified).

How we measured this

Confidence in this measurement: medium.

  • Realtime quality was not measured this run. It does not count against the grade.
  • The feed was downloaded from the configured feed URL. Publisher ownership of that URL is not verified.

Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.

Top things to fix

Fix 01

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

Block trips with overlapping stop times (flagged by the MobilityData validator). See the linked rule for what this affects.

⏱ Varies.worth about +24 points in its category

Fix 02

Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.Likely your team

2432 of 2432 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.

⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 points in its category

Fix 03

Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.Likely your export tool

4181 of 4181 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

⏱ A default or per-trip field in your export.worth about +15 points in its category

How to make and check these changes

Check the result on the published feed. Read the guide, make the change in your tool, and use the next comparable run to see whether the finding is still reported. Only an action or ticket record can attribute who made the change.

  1. Review the rule documentation for 'block_trips_with_overlapping_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

Rider view: what this feed publishes

A quick read of rider-facing information in this feed.

Schedule visibility
The feed's last published service date is in 365 days.
Published accessibility data
Accessibility information is stated for 0% of stops and 0% of trips. This measures published data, not whether stops or vehicles are physically usable.
Fare information
No fare information is published in the feed.
Realtime information
Realtime-feed availability and live-arrival coverage are not known from this scorecard.

Important: This does not rate service reliability. Riders should confirm current service alerts, fares, and accessibility accommodations with the transit operator before traveling.

Show every finding
  • Error184 instances

    Block trips with overlapping stop times (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

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

  • Warning4181 instances

    4181 of 4181 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.)

    Finding code: scorecard_wheelchair_accessible_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning2432 instances

    2432 of 2432 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.)

    Finding code: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning360 instances

    Some service calendars have no days of the week switched on.

    Trips tied to these calendars never run; they are dead data that can mask real schedule problems.

    Fix: Delete the empty calendars or set their service days. (A few minutes in your scheduling software.)

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

  • Warning75 instances

    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 · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning34 instances

    Some values have extra spaces at the start or end.

    A stray space can break a match, so a stop or route may fail to link across files.

    Fix: Trim leading and trailing spaces on export. The scorecard's auto-fixed copy already does this. (Usually one export setting.)

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

  • Warning4 instances

    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.)

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

  • Warning1 instance

    A file GTFS asks for (usually feed_info.txt) is missing.

    feed_info.txt tells apps who publishes the feed and when it expires; without it nobody is warned before data goes stale.

    Fix: Add feed_info.txt with publisher name, URL, language, and feed_start_date/feed_end_date. (One small file, set once in export settings.)

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

  • Warning1 instance

    feed_info.txt is missing its start/end dates (the file itself is absent)

    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 · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning1 instance

    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 · See GTFS Best Practices (opens GTFS Best Practices on an external site)

  • Info1615 instances

    The feed has a stretch of two weeks or more with no service running.

    A long gap can mean dates were left out of the calendar. Apps then show no trips on those days.

    Fix: Check whether the gap is real, like a seasonal break; if not, add the missing dates to the calendar. (A review of your calendar dates.)

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

Cite this record

This page updates on every check. The record below does not: it is the dated file this grade came from, published at https://gtfsscorecard.org/data/artifacts/plymouth-citybus/2026-09-01.json and never overwritten, pinning the grade, category scores, rubric version, validator version, reader archive profile, and the scored feed's sha256 as they stood on 2026-09-01. Use it in a board packet, a regulatory filing, or a research citation instead of linking the live page, whose content will differ on your next visit.
