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 v1.4, validator 8.0.1.
Checked for changes 37 minutes ago; last changed 6 hours ago.
Measured 3 of 4 score categories from the official feed URL on file.
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.
About this feed
Réseau urbain TAG’s published feed lists 54 routes (tram / light rail and bus), 21,462 scheduled trips and 2,527 stops. The published file last changed on 2026-10-16.
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 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
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
838 of 2527 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.
Fixing this covers 838 of 2,527 stops, about 33% of them.
⏱ A column in stops.txt; your scheduling software likely has it.worth about +8 points in its category
Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt.Likely your export tool
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.
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.
⏱ Usually one export setting.worth about +8 points in its category
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.

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.
Fix 01 · Read the fix guide for scorecard_missing_feed_info_dates
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. See this feed's finding-clearance log.
Fix 02 · Read the fix guide for scorecard_wheelchair_boarding_unknown
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. See this feed's finding-clearance log.
Fix 03 · Read the fix guide for equal_shape_distance_same_coordinates
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. See this feed's finding-clearance log.
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 76 days.
- Published accessibility data
- Accessibility information is stated for 66.8% of stops and 100% of trips. This measures published data, not whether stops or vehicles are physically usable.
- Fare information
- Fare information is published using GTFS Fares v1.
- 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.
Send your vendor a fix request
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
The MobilityData validator flagged 10 kinds of issue across 771 instances (0 error, 130 warning, 641 informational).
Service data covers the next 76 days.
67% of stops state wheelchair accessibility (45% marked accessible, 22% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is published.
67% of stops state accessibility (45% marked accessible). Reflects what the feed states, not verified physical usability.
3 accessibility depth signals
37 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (C10, C14, 16, 17, 18, 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.
4 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Crolles, ST Microelectronics", "Crolles, ST Microelectronics", "Crolles, ST Microelectronics", and more).
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.

838 of 2527 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 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.)

- Warning14 instances
Some stops sit far from the route line they belong to.
Trip planners may draw the transit vehicle route through the wrong path or point riders to the wrong boarding location.
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.)

- Warning7 instances
On some trips the stops fall along the route line in a different order than the schedule lists.
Trip planners can draw the transit vehicle 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.)

- Warning4 instances
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)
- Warning3 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.)
Finding code: expired_calendar · Read the fix guide for expired_calendar · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
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.)

- Warning1 instance
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)
- 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.)
Finding code: scorecard_station_no_pathways · Read the fix guide for scorecard_station_no_pathways · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Info524 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)
- Info88 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.)

Unsorted stop times (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'unsorted_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Finding code: unsorted_stop_times · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info1 instance
Some files contain columns that are not part of the GTFS spec.
Harmless to riders, but apps ignore these columns and they can hide typos in real column names.
Fix: Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras. (A quick look at the flagged files.)
Finding code: unknown_column · Read the fix guide for unknown_column · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- 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.)

This feed includes flexible (demand-responsive) service, and riders are told how to book it.
Dial-a-ride and zone service are described for trip planners, not just fixed routes.
Fix: No action needed. (None.)

Conformance mark Not yet
One requirement remains for this feed to earn the conformance mark. States wheelchair access on 67% of stops and 100% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 76 days.
- Accessible Not yet
- States wheelchair access on 67% of stops and 100% of trips; the mark needs 90% of each.
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 76 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 65 / 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 84 / 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-83459/2026-10-16.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.
