Trenitalia's regional rail service in Sardegna, distinct from the Toscana Trenitalia record; counted as one feed record.

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

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

42 of 42 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

Fix 02

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

Fix 03

Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE').Likely your export tool

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.

⏱ Often a bulk fix in your scheduling software.worth about +8 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.

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 147 days.
Published accessibility data
Accessibility information is stated for 0% of stops and 51.5% of trips. This measures published data, not whether stops or vehicles are physically usable.

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

6 findings, ordered by severity.

Show every finding
  • Warning386 instances

    386 of 796 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.)

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

  • Warning95 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.)

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

  • Warning42 instances

    42 of 42 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

  • Warning1 instance

    Missing feed contact email and url (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

    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

  • 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.)

Conformance mark Not yet

This feed is close to the conformance mark. States wheelchair access on 0% of stops and 52% of trips; the mark needs 90% of each.

Valid Met
Passes validation with no errors.
Current Met
Service data covers the next 147 days.
Accessible Not yet
States wheelchair access on 0% of stops and 52% 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 147 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
