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 3 hours ago; last changed 42 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 6 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.

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 was 213 days ago.
- 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
- No realtime feed was reachable during sampling.
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
The MobilityData validator flagged 6 kinds of issue across 508 instances (0 error, 508 warning, 0 informational).
Service data ended 213 day(s) ago. Trip planners have likely already dropped this feed.
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.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.

Show every finding
- Error1 instance
Service data ended 213 day(s) ago.
When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.
Fix: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. (Usually one export setting; export on a schedule so it never lapses again.)
Finding code: scorecard_feed_expired · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Error1 instance
The trip updates realtime feed failed during sampling.
When this feed is down, riders see scheduled times presented as if they were live.
Fix: Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request. (Usually a vendor support ticket.)
Finding code: scorecard_rt_trip_updates_unreachable · Read the fix guide · See GTFS-Realtime reference (opens the GTFS-Realtime reference on an external site)
- Error1 instance
The vehicle positions realtime feed failed during sampling.
When this feed is down, riders see scheduled times presented as if they were live.
Fix: Check the vehicle positions endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request. (Usually a vendor support ticket.)
Finding code: scorecard_rt_vehicle_positions_unreachable · Read the fix guide · See GTFS-Realtime reference (opens the GTFS-Realtime reference on an external site)
- Warning2495 instances
2495 of 2495 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)
- Warning2218 instances
2218 of 2218 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)
- Warning285 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)
- Warning170 instances
Some route lines list the same point twice in a row.
Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.
Fix: Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt. (Usually one export setting.)
Finding code: equal_shape_distance_same_coordinates · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning48 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.)
Finding code: equal_shape_distance_diff_coordinates_distance_below_threshold · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- 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.)
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
A file GTFS asks for (usually feed_info.txt) is missing.
feed_info.txt tells apps who publishes the feed and when it expires; without it nobody is warned before data goes stale.
Fix: Add feed_info.txt with publisher name, URL, language, and feed_start_date/feed_end_date. (One small file, set once in export settings.)
Finding code: missing_recommended_file · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
Many of the feed's trips don't run at all in the next 7 days.
It usually means old service periods are still in the export, making the feed bigger and harder to check.
Fix: Trim past service periods the next time you export. (One setting in most export tools.)
Finding code: trip_coverage_not_active_for_next7_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
feed_info.txt is missing its start/end dates (the file itself is absent)
Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.
Fix: Add feed_info.txt with feed_start_date and feed_end_date to your export. (Two fields, set once in export settings.)
Finding code: scorecard_missing_feed_info_dates · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules 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)
- 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 Not ready
Resolve this before you certify on the D-10. Service data expired 213 days ago, so FTA would find the link out of date.
- Published Ready
- Published at a public URL.
- Valid Ready
- Passes validation with no errors.
- Current Not ready
- Service data expired 213 days ago, so FTA would find the link out of date.
- 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 2495 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 expired 213 days ago. 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 expired 213 days ago.
- 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 0.0% of 200 checks over the last 34 days, with lag not reported by the feed.
Sampled on a schedule between full scores, so this tracks uptime and freshness over time rather than at a single moment.
Below the Google and Apple Maps four-week coverage bar. This feed's last day of service has passed, so Google and Apple Maps will stop showing your agency. Re-export with a calendar that covers at least the next four weeks.
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 66 / 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 0 / 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 38 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
- Realtime quality 0 / 100
- GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.

The record below does not: it is the dated file this grade came from, published at https://gtfsscorecard.org/data/artifacts/suffolk-county-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.
