First scorecard for this agency

Catalogued in Grand-Est, France.

Covers 60 daysAccessibility gaps

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 1 hours ago; last changed 1 hours ago.

Measured 4 of 4 score categories from the official feed URL on file.

How we measured this

Confidence in this measurement: high.

  • All four score categories were measured this run.
  • Realtime was sampled in one bounded window of 3 snapshots.
  • 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

Fix 01

Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out.

43 of 112 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.

⏱ A vendor data-mapping question.worth about +16 points in its category

Fix 02

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

14259 of 14259 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the transit vehicle itself can take them.

⏱ A default or per-trip field in your export.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

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 60 days.
Published accessibility data
Accessibility information is stated for 48.2% 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
Live-arrival data covered 61.6% of scheduled trips in the sampled window.

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

Correctness49.0 / 100

The MobilityData validator flagged 9 kinds of issue across 12567 instances (0 error, 11085 warning, 1482 informational).

Freshness100.0 / 100

Service data covers the next 60 days.

Rider experience34.9 / 100

48% of stops state wheelchair accessibility (48% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.

Accessibility30.1 / 100

48% of stops state accessibility (48% marked accessible). Reflects what the feed states, not verified physical usability.

3 accessibility depth signals

  • 19 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (E1, E3, E4, E7, O1, 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.

  • 45 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("ST BRICE GARE", "ST BRICE GARE", "ST BRICE GARE", 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.

Realtime quality83.7 / 100

Sampled 3 times: 1 of 1 configured feed healthy; 61.6% of scheduled trips had live predictions; predictions ran a median of 126s behind schedule.

Over time

This is the first scorecard for this agency. A trend and a "what changed" summary appear here once it has been checked more than once.

Everything we checked

17 findings, ordered by severity.

Show every finding
  • Warning14259 instances

    14259 of 14259 trips don't say whether the vehicle is wheelchair accessible.

    Even with accessible stops, riders need to know the transit vehicle 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)

  • Warning7930 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)

  • Warning2544 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 path or point riders to the wrong boarding location.

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

  • Warning638 instances

    638 of 1232 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)

  • Warning556 instances

    Equal shape distance diff coordinates distance below threshold (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

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

  • Warning43 instances

    43 of 112 trips scheduled during the sampling window had no live predictions.

    Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.

    Fix: Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out. (A vendor data-mapping question.)

    Finding code: scorecard_rt_trip_coverage · Read the fix guide · See GTFS-Realtime reference (opens the GTFS-Realtime reference on an external site)

  • Warning28 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 · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning15 instances

    Some route long names repeat the route's short name inside them.

    Apps show both names together, so riders see the number twice, like '5 5 Downtown'.

    Fix: Drop the short name from route_long_name and keep the long name descriptive, like 'Downtown via 5th Ave'. (One field per flagged route.)

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

  • Warning8 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 · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning3 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.)

    Finding code: route_color_contrast · Read the fix guide · 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.)

    Finding code: missing_feed_contact_email_and_url · 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)

  • 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 · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning1 instance

    Realtime data was up to 69 seconds old when sampled.

    Stale positions and predictions are worse than none: riders watch a transit vehicle that already left.

    Fix: Ask your AVL vendor to send updates at least every 20 seconds. That is the Caltrans guideline. (A vendor configuration question.)

    Finding code: scorecard_rt_stale

  • Info1482 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)

  • Info1207 instances

    About 1207 stop names are written in ALL CAPS.

    Mixed-case names are easier to read in apps and are read more naturally by screen readers.

    Fix: Rename stops to mixed case where the language has letter case (for example, 'Central Station'). (Often a bulk fix in your scheduling software.)

    Finding code: scorecard_stop_names_all_caps · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices 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.)

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

Conformance mark Not yet

One requirement remains for this feed to earn the conformance mark. States wheelchair access on 48% of stops and 0% of trips; the mark needs 90% of each.

Valid Met
Passes validation with no errors.
Current Met
Service data covers the next 60 days.
Accessible Not yet
States wheelchair access on 48% of stops and 0% 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.

Realtime reliability

The realtime feed responded on 100.0% of 5 checks over the last 1 day, with 53s median lag.

Sampled on a schedule between full scores, so this tracks uptime and freshness over time rather than at a single moment.

Live predictions vs schedule

Arrival predictions ran a median 126s late versus the schedule, and stayed within 1404s nine times in ten. They were on time (about a minute early to five late) 52.8% of the time.

From the last full realtime sample: how far live arrival predictions sat from the schedule, and whether vehicle positions fell on the route. These feed the realtime score; they change no other category.

Clears the Google and Apple Maps four-week coverage bar. This feed has 60 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 49 / 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 100 / 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 35 / 100
GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
Realtime quality 84 / 100
GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.
