Checked for changes 9 hours ago; last changed 41 days ago.

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

963 of 963 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

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

2325 of 2325 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

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

Fix 03

Remove retired stops from the export, or add them back to the trips that should serve them.Likely your export tool

Some stops exist in the feed but no trip ever stops at them. Riders may walk to a stop where no bus is scheduled to arrive.

⏱ A review pass in your scheduling software.worth about +8 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 31 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
Fare information is published using GTFS Fares v1.
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.

Freshness51.7 / 100

Service data covers the next 31 days.

Rider experience59.8 / 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 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 (BSU 5).

    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.

  • 836 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Belair St at 7-Eleven", "Belair St at 7-Eleven", "Belair St at Colonel Bell Drive", and more).

    Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.

Everything we checked

10 findings, ordered by severity.

Show every finding
  • Warning2325 instances

    2325 of 2325 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)

  • Warning963 instances

    963 of 963 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)

  • Warning173 instances

    Some stops exist in the feed but no trip ever stops at them.

    Riders may walk to a stop where no bus is scheduled to arrive.

    Fix: Remove retired stops from the export, or add them back to the trips that should serve them. (A review pass in your scheduling software.)

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

  • Warning11 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)

  • Warning1 instance

    This feed describes flexible (demand-responsive) service but has no booking_rules.txt.

    Riders can see the service area but not how or when to reserve a trip, so they can't actually use the service.

    Fix: Add booking_rules.txt saying how far ahead and how to book (phone, app, or web). (A small file; one rule often covers the whole service.)

    Finding code: scorecard_flex_no_booking_rules · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Info102 instances

    Some trip headsigns name a stop along the way, not the final destination.

    The sign should tell riders where the bus 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)

  • Info34 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.)

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

  • Info8 instances

    The feed includes a file that is not part of the GTFS spec.

    Apps ignore files they don't know, and a stray file can hide a misspelled standard file name.

    Fix: Check the flagged file name for a typo of a standard GTFS file. Remove it if it is a vendor extra. (A quick look at the flagged file.)

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

  • Info4 instances

    Some service dates fall outside the date window set in feed_info.txt.

    feed_info.txt should span every day your service runs, so apps know when the data applies.

    Fix: Widen feed_start_date and feed_end_date to cover all service dates, or fix the dates that fall outside. (Two fields in feed_info.txt, or one export setting.)

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

  • Info4 instances

    Stop without zone id (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

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

Beyond the grade

Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.

  • Flex zones are published but no booking_rules.txt is present.

    Consider: Add booking_rules.txt with how far ahead and how to reserve (phone, app, or web).

NTD GTFS readiness Ready

Published at a public URL, valid, current, and identified with agency_id: the four feed checks for RY2026 all hold here. Only your own D-10 and P-50 filings make that official; this is a heads-up, not a determination.

Published Ready
Published at a public URL.
Valid Ready
Passes validation with no errors.
Current Ready
Service data covers the next 31 days.
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 2325 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. 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 Met
Service data covers the next 31 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.

Can riders use it?

Checks beyond structural validation: places where the feed is valid but a rider still could not travel.

  • 173 of 963 boardable stops are never served by any trip. Riders see these stops in apps and on the map but can never catch anything there, which erodes trust in the data. Remove stops no route serves, or add the trips that should call at them.

These do not change the grade. They catch trips with no rideable leg and stops no trip serves, the kind of gap a trip planner trips over.

Clears the Google and Apple Maps four-week coverage bar. This feed has 31 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. Read the full standards crosswalk.

Correctness 82 / 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. FTA NTD readiness also checks that the published feed is valid.
Freshness 52 / 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. FTA NTD readiness also checks that the published feed is current.
Rider experience 60 / 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.
