Covers 262 daysAccessibility gapsRealtime not yet published

Naruto City's municipal ferry (市営渡船) service, scored on the same GTFS Schedule rubric as any fixed-route feed; 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 terminal. A field survey can start with the busiest terminals.Likely your team

6 of 6 terminals 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

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

118 of 118 trips don't say whether the vehicle is wheelchair accessible. Even with accessible terminals, riders need to know the vessel itself can take them.

⏱ A default or per-trip field in your export.worth about +15 points in its category

Fix 03

Only change the flagged IDs if an app needs basic ASCII values. Update each place that uses the ID. Keep all names and headsigns in their original language.

Some internal IDs use characters outside the basic text set. These IDs are valid UTF-8 data. This warning is only about support in older apps. It does not mean that names in other languages are wrong.

⏱ A planned ID change, not a quick text cleanup.worth about +8 points in its category

How to make and check these changes

Ferry data profile

A ferry-specific view of what this GTFS feed publishes. Schedule measurements use ferry routes and trips only; fare and realtime facts are labelled as whole-feed. Unknown values are not treated as no.

Ferry service
3 routes · 118 trips
Terminal structure
6 ferry boarding locations; no parent-station hierarchy is published.
Terminal access
Not applicable: no ferry boarding location is linked to a parent station, so stop_access is not permitted here.
Published accessibility
Unknown: none of the 6 ferry boarding locations publish wheelchair_boarding. Unknown: none of the 118 ferry trips publish wheelchair_accessible. This reports published values, not verified physical usability.
Bicycles
Unknown: none of the 118 ferry trips publish bikes_allowed.
Cars
Unknown: none of the 118 ferry trips publish cars_allowed.
Fares
Whole feed: applied fare data is published using GTFS Fares v1.

  • Warning509 instances

    Some internal IDs use characters outside the basic text set.

    These IDs are valid UTF-8 data. This warning is only about support in older apps. It does not mean that names in other languages are wrong.

    Fix: Only change the flagged IDs if an app needs basic ASCII values. Update each place that uses the ID. Keep all names and headsigns in their original language. (A planned ID change, not a quick text cleanup.)

    Validator rule: non_ascii_or_non_printable_char · See MobilityData GTFS Validator rules

  • Warning118 instances

    Missing bike allowance (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

    Validator rule: missing_bike_allowance · See MobilityData GTFS Validator rules

  • Warning118 instances

    118 of 118 trips don't say whether the vehicle is wheelchair accessible.

    Even with accessible terminals, riders need to know the vessel 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

  • Warning6 instances

    6 of 6 terminals 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 terminal. A field survey can start with the busiest terminals. (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

  • Warning3 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

  • 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

    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.)

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

  • Info2 instances

    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.)

    Validator rule: unknown_column · 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.)

Conformance mark Not yet

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

Valid Met
Passes validation with no errors.
Current Met
Service data covers the next 262 days.
Accessible Not yet
States wheelchair access on 0% of terminals 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 terminal and trip is wheelchair accessible.

A pass credential for a feed that is valid, current, and states wheelchair access on nearly every terminal and trip. Accessibility here measures what the feed publishes, not whether a terminal is physically usable. How the conformance mark works.

Clears the Google and Apple Maps four-week coverage bar. This feed has 262 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 72 / 100
