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 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.

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 1328 days.
- Published accessibility data
- Accessibility information is stated for 83.3% of terminals and 0% of trips. This measures published data, not whether terminals or vessels are physically usable.
- Fare information
- No fare information is published in the feed.
- 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.

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
- 4 routes · 310 trips
- Terminal structure
- 12 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
- 83.3% of ferry boarding locations publish a value; 83.3% of all ferry boarding locations explicitly say allowed (10 of 12). Unstated values remain unknown. Unknown: none of the 310 ferry trips publish wheelchair_accessible. This reports published values, not verified physical usability.
- Bicycles
- 100% of ferry trips publish a value; 100% of all ferry trips explicitly say allowed (310 of 310). Unstated values remain unknown.
- Cars
- Unknown: none of the 310 ferry trips publish cars_allowed.
- Fares
- Whole feed: no applied fare data is published. This is not evidence that ferry service is free.
- Realtime
- Whole feed: no GTFS-Realtime endpoints are configured in this scorecard.
Descriptive only. This profile does not change the grade or verify vessels, terminal facilities, vehicle carriage, fares, or accessibility in the real world. Field meanings follow the GTFS Schedule reference.

Missing timepoint value (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'missing_timepoint_value' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

- Warning310 instances
310 of 310 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.)

- Warning51 instances
51 of 310 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)
- 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 vessel 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)
- Warning2 instances
Some terminals sit far from the route line they belong to.
Trip planners may draw the vessel route through the wrong path or point riders to the wrong terminal.
Fix: Check the flagged terminals' coordinates and the route shape in your scheduling software; re-snap whichever is misplaced. (A few minutes per flagged terminal.)

2 of 12 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.)
Finding code: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference 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.)

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

Same name and description for stop (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'same_name_and_description_for_stop' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

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.)

Service extends far in the future (flagged by the MobilityData validator).
See the linked rule for what this affects.

- 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)
- 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.)

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 1328 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 310 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 83% 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 1328 days.
- Accessible Not yet
- States wheelchair access on 83% 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 1413 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 71 / 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 100 / 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 56 / 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.
