First scorecard for this agency
Catalogued in South Carolina.
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.

Make the change. Make this change in whatever tool produces your feed, then re-export.
Check the result. The next scorecard run checks this finding again. If a comparable check no longer reports it, the feed's clearance log records that result. This confirms feed state, not who made the change. Self-check a feed before you publish.
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 129 days.
- Published accessibility data
- Accessibility information is stated for 100% of terminals and 100% of trips. This measures published data, not whether terminals or vessels 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.

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
- 2 routes · 16 trips
- Terminal structure
- 3 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
- 100% of ferry boarding locations publish a value; 100% of all ferry boarding locations explicitly say allowed (3 of 3). Unstated values remain unknown. 100% of ferry trips publish a value; 100% of all ferry trips explicitly say allowed (16 of 16). Unstated values remain unknown. This reports published values, not verified physical usability.
- Bicycles
- 100% of ferry trips publish a value; 0% of all ferry trips explicitly say allowed (0 of 16). Unstated values remain unknown.
- Cars
- Unknown: none of the 16 ferry trips publish cars_allowed.
- Fares
- Whole feed: applied fare data is published using GTFS Fares v1.
- 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.

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 129 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 16 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 Awarded
This feed earns the conformance mark: valid, current, and stating wheelchair access on nearly every terminal and trip.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 129 days.
- Accessible Met
- States wheelchair access on 100% of terminals and 100% of trips.
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 129 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.

- Correctness 96 / 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 100 / 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.

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/fort-sumter-ferry/2026-07-19.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 2026-07-19. 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.
