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 44 minutes ago; last changed 2 days ago.

Measured 3 of 4 score categories from the agency's own feed.

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 agency's own URL.

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 'invalid_row_length' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

Invalid row length (flagged by the MobilityData validator). See the linked rule for what this affects.

⏱ Varies.worth about +12 points in its category

Fix 02

Add feed_info.txt with feed_start_date and feed_end_date to your export.Likely your export tool

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.

⏱ Two fields, set once in export settings.worth about +15 points in its category

Fix 03

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.

The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

⏱ A small file for most flat-fare systems.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 'invalid_row_length' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Make the change. Make this change in whatever tool produces your feed, then re-export.

    Check the result. The next scorecard run checks this finding again. If a comparable check no longer reports it, the feed's clearance log records that result. This confirms feed state, not who made the change. Self-check a feed before you publish.

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 151 days.
Published accessibility data
Accessibility information is stated for 100% of stops and 100% 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.

You may not control the GTFS export yourself. Copy this and send it to whoever runs your scheduling software export. It names each fix with the validator notice and a guide link.

Score by category

Correctness66.0 / 100

The MobilityData validator flagged 6 kinds of issue across 11 instances (1 error, 10 warning, 0 informational).

Freshness85.0 / 100

Service data covers the next 151 days.

Rider experience77.5 / 100

100% of stops state wheelchair accessibility (100% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.

Accessibility100 / 100

100% of stops state accessibility (100% marked accessible). Reflects what the feed states, not verified physical usability.

1 accessibility depth signal

  • 1 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (BREST-OUESSANT).

    Consider: Adjust route_color or route_text_color so each pair clears 4.5:1. Often switching the text between black and white is enough.

Opportunities to strengthen the data, not deductions from the sub-score above. States what the second accessibility lens can check from the feed, not verified physical usability.

Everything we checked

9 findings, ordered by severity.

Show every finding
  • Error1 instance

    Invalid row length (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

    Finding code: invalid_row_length · See MobilityData GTFS Validator rules

  • Warning6 instances

    Some internal IDs use characters outside the basic text set.

    These IDs are valid UTF-8 data. This warning is only about support in older apps. It does not mean that names in other languages are wrong.

    Fix: Only change the flagged IDs if an app needs basic ASCII values. Update each place that uses the ID. Keep all names and headsigns in their original language. (A planned ID change, not a quick text cleanup.)

    Finding code: non_ascii_or_non_printable_char · See MobilityData GTFS Validator rules

  • 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

  • Warning1 instance

    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

  • Warning1 instance

    Route short name too long (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

    Finding code: route_short_name_too_long · See MobilityData GTFS Validator rules

  • Warning1 instance

    Unexpected enum value (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

    Finding code: unexpected_enum_value · See MobilityData GTFS Validator rules

  • 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

  • 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

  • Info1 instance

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

    Trip-planning apps and regional data coordinators have nobody to email when they spot a problem with your feed, so problems linger.

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

    Finding code: scorecard_no_feed_contact · Read the fix guide · See MobilityData GTFS Validator rules

Conformance mark Not yet

This feed is close to the conformance mark. 1 validator error to resolve.

Valid Not yet
1 validator error to resolve.
Current Met
Service data covers the next 151 days.
Accessible Met
States wheelchair access on 100% of stops and 100% of trips.

In plain words: earn this mark when your feed passes validation, has not expired, and says whether nearly every stop and trip is wheelchair accessible.

A pass credential for a feed that is valid, current, and states wheelchair access on nearly every stop and trip. Accessibility here measures what the feed publishes, not whether a stop is physically usable. How the conformance mark works.

Clears the Google and Apple Maps four-week coverage bar. This feed has 151 days of service ahead, clearing the four-week (28-day) window Maps asks for. The feed also carries 1 validator error, the other thing Maps checks at onboarding; the findings below name each fix.

How this agency maps to the standards

The scorecard is a data-quality lens, not a compliance determination. Its universal references describe good GTFS and useful rider information. Useful references here are GTFS Schedule Best Practices, GTFS-Realtime Best Practices, MobilityData grading scheme, Google Transit publication guidance. Read the full standards crosswalk.

Correctness 66 / 100
GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading covers stop locations, route names, and colors. Google Transit requires a feed to pass validation for publication.
Freshness 85 / 100
GTFS Schedule best practices call for a dataset that stays current. An expired calendar can remove service from Google Transit and other rider trip planners.
Rider experience 78 / 100
GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
Realtime quality Not yet published
GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.

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/fr-pan-82872/2026-08-02.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 2026-08-02. 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.
