How we measured this

Confidence in this measurement: high.

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

47 of 47 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

Fix 02

Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).Likely your export tool

369 of 369 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

⏱ Often one default setting in your export.worth about +15 points

Agencies here usually clear this within about 1 week (based on 5 observed fixes).

Fix 03

Populate trip_headsign to match what the bus displays.Likely your export tool

369 of 369 trips have no headsign. Riders at the stop can't tell which direction a bus is going.

⏱ Usually a bulk edit in your scheduling software.worth about +15 points

Score by category

Correctness95.5 / 100

The MobilityData validator flagged 2 kinds of issue across 3 instances (0 error, 1 warning, 2 informational).

Freshness50.0 / 100

Service data covers the next 30 days.

Rider experience30.0 / 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

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

    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.

  • 41 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Campus View Dr at Sheppard Pratt (EB)", "Dulaney Valley Rd at Towson Town Center Mall - Macy's (NB)", "Dulaney Valley Rd at Towson Town Center Mall (Macy's) (SB)", 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.

Everything we checked

NTD certification readiness Needs attention

This feed is close to NTD-ready. Service data runs out in 30 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 30 days; renew before you certify.
agency_id matches your NTD ID Not checked yet
Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
shapes.txt covers your trips Ready
All 369 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 and confirm it once a year. This box is a heads-up on whether yours looks ready; it is not the official sign-off.

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). Aligning agency_id with your NTD ID lets the feed line up with your NTD record; the July 2025 final rule links the two on the P-50 form rather than requiring that feed change, and 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 30 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 30 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 105 checks over the last 16 days, with 3s 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 540 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

A data-quality lens, not a compliance determination. Each category shows this feed's score and the standards it relates to: the FTA National Transit Database GTFS requirement, the MobilityData grading scheme, and the Google Transit gate. Read the full standards crosswalk.

Correctness 96 / 100
GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading: stop locations, route names and colors. Google Transit: a feed must pass validation to stay in Maps.
Freshness 50 / 100
The FTA National Transit Database expectation of a valid, current feed. Google Transit: an expired calendar drops the agency from Maps.
Rider experience 30 / 100
GTFS Best Practices for rider-facing fields. MobilityData grading: stop names and headsigns.
Realtime quality 100 / 100
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/towson-loop/2026-07-09.json and never overwritten, pinning the grade, category scores, rubric version, validator version, and the scored feed's sha256 as they stood on 2026-07-09. Use it in a board packet, an NTD narrative, or a research citation instead of linking the live page, whose content will differ on your next visit.
