First scorecard for this agency
Catalogued in California.
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.

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 167 days.
- Published accessibility data
- Accessibility information is stated for 15.6% of stops and 84.2% 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.

Score by category
The MobilityData validator flagged 3 kinds of issue across 41 instances (0 error, 1 warning, 40 informational).
Service data covers the next 167 days.
16% of stops state wheelchair accessibility (0% marked accessible, 16% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is published.
16% 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 (Lompoc, Santa).
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.
9 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Hollister at Cremona Dr.", "Hollister & Cremona", "Hollister & Los Carneros Way", 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.
Fares are applied to trips.
Not scored yet. Nothing here counts against the grade.
Routes and stops
Each route is drawn once, using the longest shape its trips follow; stops are the dots.

38 of 45 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.)

6 of 38 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.)

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

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.)

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 167 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 38 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 16% of stops and 84% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 167 days.
- Accessible Not yet
- States wheelchair access on 16% of stops and 84% 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.
Clears the Google and Apple Maps four-week coverage bar. This feed has 167 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.
In California, the published guideline is California Transit Data Guidelines. Caltrans' published quality guidelines and compliance checklist; this rubric is anchored to them.
California Minimum GTFS Guidelines checklist (5 of 6 measured items met)
The state's own Data Process Checklist, matched item by item to what this scorecard already measures. An item marked "not measured here" is real ground the checklist covers that this tool does not check; see the official checklist for the full picture.
- Meets Publish GTFS Schedule at a stable, automatically-fetchable URL
The published feed URL downloaded at the last check.
- Not measured here Implement required fields: Fares v2, text-to-speech stop names, shapes.txt, wheelchair_boarding, and Pathways where applicable
This scorecard measures wheelchair_boarding, shapes.txt coverage, fare data, and station pathways separately, below; it does not check the Fares v2 format specifically or text-to-speech stop names.
- Not measured here Achieve a passing score in every category of the MobilityData GTFS Grading Scheme v1
This scorecard automates a proxy for the Grading Scheme's rider-facing fields (see the standards crosswalk) rather than running the scheme itself, which grades by comparison to the real world by hand.
- Not measured here Publish changes to the base schedule at least one week ahead of every service change
This scorecard does not track a feed's publish history, so advance notice cannot be checked.
- Meets Produce no critical errors in the MobilityData GTFS Validator
Passes validation with no errors.
- Not measured here Publish Trip Updates, Vehicle Positions, and Alerts feeds
This scorecard checks realtime reachability and freshness overall; it does not check for all three feed types individually.
- Not measured here Update Trip Updates and Vehicle Positions at least every 20 seconds
This scorecard samples realtime freshness; it does not check this specific 20-second cadence.
- Not measured here Publish information for at least 99% of vehicles in service
This scorecard measures the share of scheduled trips represented in TripUpdates, a related but different figure than vehicle coverage.
- Not measured here Keep 100% of trip_ids consistent between Schedule and Realtime
This scorecard does not currently check trip_id consistency between the Schedule and Realtime feeds.
- Not measured here Produce no critical errors in the Center for Urban Transportation Research realtime validator
This scorecard does not run the CUTR realtime validator.
- Not measured here Publish accessible feed links on the agency or regional partner website
This scorecard does not check the agency's own website.
- Not measured here Register GTFS and GTFS-Realtime feeds with transit.land and the Mobility Database
This scorecard does not currently check aggregator registration for this section.
- Meets Designate a technical contact in feed_info.txt's feed_contact_email
feed_info.txt states a technical contact.
- Gap wheelchair_boarding stated on stops and trips
States wheelchair access on 16% of stops and 84% of trips.
- Meets shapes.txt with a shape for every trip
All 38 trips have a shape in shapes.txt.
- Meets Fare data published, or the service marked fare-free
Fare data is published.
- Correctness 95 / 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 76 / 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.
