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 5 hours ago; last changed 1 days ago.

The latest run did not download this feed: the host's robots.txt asks automated tools not to request it, and this scorecard follows that. The grade shown was measured on 2026-10-22.

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 Coralie’s published feed lists 42 bus routes, 2,692 scheduled trips and 560 stops. The published file last changed on 2026-10-16.

Top things to fix

Fix 01

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

Trip distance exceeds shape distance (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 +24 points in its category

Fix 02

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.

Stop time with arrival before previous departure time (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 +24 points in its category

Fix 03

Re-generate shape distances in your export; flag to your vendor if it persists.Likely your export tool

Some trips have stop times whose distances along the route go backwards. Apps can show buses jumping backwards or mis-order stops.

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.

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.

Finding handoff

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. Fix 01

    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.

  2. Fix 02

    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.

  3. Fix 03

    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 2647 days.
Published accessibility data
Accessibility information is stated for 13.9% of stops and 99.2% 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.

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

Correctness0.0 / 100

The MobilityData validator flagged 15 kinds of issue across 2771 instances (363 error, 2338 warning, 70 informational).

Freshness85.0 / 100

Service data covers the next 2647 days.

Rider experience55.9 / 100

14% of stops state wheelchair accessibility (14% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.

Accessibility45.9 / 100

14% of stops state accessibility (14% marked accessible). Reflects what the feed states, not verified physical usability.

2 accessibility depth signals

  • 10 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (4, 14, 12, 13, 16, 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 ("Collège St Michel", "Rd Pt Rue de Pont-aven", "St Mathieu").

    Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.

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

20 findings, ordered by severity.

Show every finding
  • Error181 instances

    Trip distance exceeds shape distance (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

  • Error174 instances

    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.)

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

  • Error8 instances

    Some trips have stop times whose distances along the route go backwards.

    Apps can show buses jumping backwards or mis-order stops.

    Fix: Re-generate shape distances in your export; flag to your vendor if it persists. (Usually an export-tool fix, not hand editing.)

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

  • Warning1817 instances

    On some trips the stop distances run a little past the end of the route line.

    The stop and shape distance values don't quite line up, so any math that uses them can drift.

    Fix: Re-generate shape_dist_traveled on export so stop and shape distances use the same units. (Usually an export-tool fix, not hand editing.)

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

  • Warning482 instances

    482 of 560 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 for scorecard_wheelchair_boarding_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning366 instances

    Some stops sit far from the route line, going by the feed's own distance values.

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

    Fix: Check the flagged stops' shape_dist_traveled against the route shape, and re-generate it on export if they disagree. (Usually an export-tool fix, not hand editing.)

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

  • Warning70 instances

    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)

  • Warning69 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 for stop_too_far_from_shape · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning21 instances

    21 of 2692 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 for scorecard_wheelchair_accessible_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning9 instances

    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.)

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

  • Warning2 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 for mixed_case_recommended_field · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning2 instances

    Some route colors don't contrast with their text color.

    Route badges get hard to read, most of all for riders with low vision.

    Fix: Pick a darker/lighter route_text_color for the flagged routes. (One field per route.)

  • Warning2 instances

    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.)

  • 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.)

  • 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.)

  • Info44 instances

    Service extends far in the future (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

  • Info21 instances

    Some trip headsigns name a stop along the way, not the final destination.

    The sign should tell riders where the bus 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)

  • Info5 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.)

Accessible Not yet
States wheelchair access on 14% of stops and 99% 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 2647 days of service ahead, clearing the four-week (28-day) window Maps asks for. The feed also carries 363 validator errors, 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.

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-81476/2026-10-22.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 2026-10-22. 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.
