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 79 minutes ago; last changed 41 days ago.

Measured 4 of 4 score categories from the agency's own feed.

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 9 snapshots.
  • 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

Re-export with a validity window that reaches at least 60 days out.Likely your export tool

Service data runs out in 28 day(s). When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.

⏱ One export setting.worth about +52 points in its category

Fix 02

Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs.

1 of 1 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

⏱ A vendor data-mapping question.worth about +41 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

1510 of 1510 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

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 28 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
Live-arrival data covered 0% 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.

Score by category

Correctness70.0 / 100

The MobilityData validator flagged 6 kinds of issue across 918 instances (0 error, 918 warning, 0 informational).

Freshness46.7 / 100

Service data runs out in 28 day(s). Publish an updated feed soon or riders will lose trip planning.

Rider experience22.5 / 100

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

Accessibility0 / 100

0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.

2 accessibility depth signals

  • 1 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (GreenLine).

    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.

  • 1441 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("04 St & 10 AE", "Superior St & 12 AE", "Superior St & 13 AE", and more).

    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.

Realtime quality58.8 / 100

Sampled 9 times: 3 of 3 configured feeds healthy; 0.0% of scheduled trips had live predictions; vehicle position plausibility was not measurable.

Everything we checked

13 findings, ordered by severity.

Show every finding
  • Warning4385 instances

    4385 of 4385 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 · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning4385 instances

    4385 of 4385 trips lack rider-facing destination or direction text.

    When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.

    Fix: Add the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign. (Usually one value per route pattern in your scheduling source.)

    Finding code: scorecard_missing_headsigns · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)

  • Warning1510 instances

    1510 of 1510 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)

  • Warning898 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 · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning7 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 · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning5 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)

  • Warning4 instances

    On some trips the stops fall along the route line in a different order than the schedule lists.

    Trip planners can draw the bus doubling back or skipping ahead, which confuses riders reading the map.

    Fix: Check the stop order and the shape direction in your scheduling software; the shape is often drawn backwards. (A few minutes per flagged trip.)

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

  • Warning3 instances

    Some service calendars have no days of the week switched on.

    Trips tied to these calendars never run; they are dead data that can mask real schedule problems.

    Fix: Delete the empty calendars or set their service days. (A few minutes in your scheduling software.)

    Finding code: service_has_no_active_day_of_the_week · 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

    Service data runs out in 28 day(s).

    When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.

    Fix: Re-export with a validity window that reaches at least 60 days out. (One export setting.)

    Finding code: scorecard_feed_expiring_soon · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices 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

    1 of 1 trips scheduled during the sampling window had no live predictions.

    Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

    Fix: Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs. (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)

  • 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.)

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

NTD GTFS readiness Needs attention

This feed is close to NTD-ready. Service data runs out in 28 days; renew before you certify.

Published Ready
Published at a public URL.
Valid Ready
Passes validation with no errors.
Current Needs attention
Service data runs out in 28 days; renew before you certify.
agency_id provided Ready
agency.txt provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk each value on the P-50 form.
agency_id equals your NTD ID (optional) Not checked yet
This feed provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk it on the P-50 form. The value does not need to equal the five-digit NTD ID; we do not have that ID on file, so the optional equality comparison is not checked yet.
shapes.txt covers your trips Ready
All 4385 trips have a shape in shapes.txt.

In plain words: if you report to the federal transit database, you have to publish a working, up-to-date feed, provide a stable agency_id for each represented reporter, and confirm the feed and P-50 crosswalk each year. This box is a heads-up; your filings are the official check.

A readiness signal mapping this feed to the FTA National Transit Database GTFS requirement (Report Year 2023 onward: a public, valid, current feed, certified annually on the D-10). For RY2026, each represented reporter needs a stable agency_id, unique within the feed and crosswalked to its five-digit NTD ID on P-50; the values do not need to be equal. FTA also requires shapes.txt in the published GTFS: Full Reporters from Report Year 2025, and Reduced, Rural, and Tribal Reporters from Report Year 2026. Not an official determination; your certification is the official check.

Conformance mark Not yet

This feed is close to the conformance mark. Service data runs out in 28 days; renew to qualify. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.

Valid Met
Passes validation with no errors.
Current Not yet
Service data runs out in 28 days; renew to qualify.
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.

Realtime reliability

The realtime feed responded on 100.0% of 200 checks over the last 34 days, with 14s median lag.

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

Clears the Google and Apple Maps four-week coverage bar. This feed has 28 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, FTA National Transit Database GTFS requirement.

Cite this record

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/duluth-transit/2026-08-01.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 2026-08-01. 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.
