First scorecard for this agency

Catalogued in Auvergne-Rhône-Alpes, France.

Covers 160 daysAccessibility gapsRealtime not yet published

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 v1.2, validator 8.0.1.

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 '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.

⏱ Varies.worth about +18 points in its category

Fix 02

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

Equal shape distance diff coordinates (flagged by the MobilityData validator). See the linked rule for what this affects.

⏱ Varies.worth about +18 points in its category

Fix 03

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

51 of 51 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.

⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 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 'trip_distance_exceeds_shape_distance' 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 160 days.
Published accessibility data
Accessibility information is stated for 0% 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
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.

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

11 findings, ordered by severity.

Show every finding
  • Error44 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.)

    Validator rule: trip_distance_exceeds_shape_distance · See MobilityData GTFS Validator rules

  • Error8 instances

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

    See the linked rule for what this affects.

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

    Validator rule: equal_shape_distance_diff_coordinates · See MobilityData GTFS Validator rules

  • Warning93 instances

    93 of 93 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.)

    Validator rule: scorecard_wheelchair_accessible_unknown · Read the fix guide · See GTFS Schedule reference

  • Warning51 instances

    51 of 51 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.)

    Validator rule: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference

  • Warning49 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.)

    Validator rule: trip_distance_exceeds_shape_distance_below_threshold · Read the fix guide · See MobilityData GTFS Validator rules

  • Warning16 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.)

    Validator rule: stop_too_far_from_shape_using_user_distance · Read the fix guide · See MobilityData GTFS Validator rules

  • Warning3 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.)

    Validator rule: equal_shape_distance_diff_coordinates_distance_below_threshold · See MobilityData GTFS Validator rules

  • 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.)

    Validator rule: missing_feed_contact_email_and_url · 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.)

    Validator rule: scorecard_no_fare_data · Read the fix guide · See GTFS Best Practices

  • Info14 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.)

    Validator rule: big_gap_in_service · Read the fix guide · See MobilityData GTFS Validator rules

  • 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.)

    Validator rule: 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. 2 validator errors to resolve. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.

Service data covers the next 160 days.
Accessible Not yet
States wheelchair access on 0% 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.

Clears the Google and Apple Maps four-week coverage bar. This feed has 160 days of service ahead, clearing the four-week (28-day) window Maps asks for. The feed also carries 52 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. 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 43 / 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 38 / 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.
