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

Top things to fix
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.
This one is about the feed as a whole, so there is no share of it to count.
⏱ Two fields, set once in export settings.worth about +15 points in its category
Review the rule documentation for 'missing_bike_allowance' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Missing bike allowance (flagged by the MobilityData validator). See the linked rule for what this affects.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.
⏱ Varies.worth about +8 points in its category
Remove past service periods the next time you export the feed.Likely your export tool
Some service calendars in the feed have already ended. Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.

Riders and need behind these fixes
- Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
- The served-area need overlays cover the United States and Canada, so none of them applies to this feed.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.

- Terminal access
- Unknown: none of the 7 eligible child terminal locations publish stop_access.
- Published accessibility
- 100% of ferry boarding locations publish a value; 71.4% of all ferry boarding locations explicitly say allowed (5 of 7). Unstated values remain unknown. 100% of ferry trips publish a value; 60% of all ferry trips explicitly say allowed (4,743 of 7,899). Unstated values remain unknown. This reports published values, not verified physical usability.

Score by category
The MobilityData validator flagged 7 kinds of issue across 181905 instances (0 error, 7911 warning, 173994 informational).
Service data covers the next 91 days.
94% of stops state wheelchair accessibility (65% marked accessible, 29% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is published.
94% of stops state accessibility (65% marked accessible). Reflects what the feed states, not verified physical usability.
3 accessibility depth signals
30 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (1B, 2, 3B, 5, C1, and more).
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.
3 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Noë St Jean", "Noë St Jean", "Noë St Jean").
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
This feed models stations or entrances but has no pathways.txt and levels.txt.
Consider: Add pathways.txt connecting entrances, platforms, and elevators, and levels.txt for each floor, so the step-free route is described.
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.
Fares are applied to trips.

Missing bike allowance (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'missing_bike_allowance' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

221 of 3617 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.)

- Warning9 instances
Some service calendars in the feed have already ended.
Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
Fix: Remove past service periods the next time you export the feed. (One setting in most export tools.)

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)
- 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.)

- 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 for scorecard_missing_feed_info_dates · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
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.)

Trip with shape dist traveled but no shape distances (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'trip_with_shape_dist_traveled_but_no_shape_distances' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

- Info1391 instances
Some trip headsigns name a stop along the way, not the final destination.
The sign should tell riders where the transit vehicle ends up, so a midpoint name can send them the wrong way.
Fix: Set trip_headsign to the trip's last stop or its overall destination. (Usually a bulk edit in your scheduling software.)
Finding code: trip_headsign_matches_intermediate_stop · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info48 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.)

- Info1 instance
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.)

Conformance mark Awarded
This feed earns the conformance mark: valid, current, and stating wheelchair access on nearly every stop and trip.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 91 days.
- Accessible Met
- States wheelchair access on 94% 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 91 days of service ahead, clearing the four-week (28-day) window Maps asks for. No validator errors either, so riders keep seeing this agency in their trip planners; warnings lower the grade here but do not remove a feed from Maps.
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 75 / 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 91 / 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.

Show your grade
Put this badge on your agency site or feed README. It updates after each completed scoring check, shows the date of that check, and links back to this scorecard. When there is no current score it says so instead of showing an old one.

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/fr-pan-84101/2026-10-16.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 2026-10-16. 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.
