Checked for changes 19 hours ago; last fetch returned HTTP 403.
Measured 3 of 4 score categories from the Mobility Database's mirror copy of the feed.
How we measured this
Confidence in this measurement: provisional.
- Realtime quality was not measured this run. It does not count against the grade.
- The agency's own feed URL was unreachable, so the Mobility Database's hosted mirror copy was scored instead.
Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.

- Error1 instance
Service data ended 882 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.)

- Warning14007 instances
14007 of 14007 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)
- Warning4754 instances
4754 of 4754 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)
- Warning45 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.)

- Warning5 instances
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.)

- Warning1 instance
This feed's service calendar runs out within the next 7 days.
When the calendar ends, Google Maps and other trip planners drop your agency entirely. Riders see no service at all.
Fix: Export and publish an updated GTFS feed that covers at least the next 30 days of service. (Usually a re-export from your scheduling software.)
Finding code: feed_expiration_date7_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
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
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)
- Info37 instances
The feed has a stretch of two weeks or more with no service running.
A long gap can mean dates were left out of the calendar. Apps then show no trips on those days.
Fix: Check whether the gap is real, like a seasonal break; if not, add the missing dates to the calendar. (A review of your calendar dates.)
Finding code: big_gap_in_service · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info34 instances
Some trip headsigns name a stop along the way, not the final destination.
The sign should tell riders where the bus ends up, so a midpoint name can send them the wrong way.
Fix: Set trip_headsign to the trip's last stop or its overall destination. (Usually a bulk edit in your scheduling software.)
Finding code: trip_headsign_matches_intermediate_stop · 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 882 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 882 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) Different (allowed)
- Your feed's agency_id is 1; your National Transit Database ID is 90014. A feed that serves several agencies (a shared regional feed) can legitimately carry more than one agency_id. The values do not need to equal the five-digit NTD ID, so this difference is allowed and carries no score. Confirm that P-50 crosswalks agency_id 1 to NTD ID 90014, and keep the feed value stable. Do not change it solely to make the two values equal.
- shapes.txt covers your trips Ready
- All 14007 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 882 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 882 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.
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.
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 0% of stops and 0% of trips.
- Meets shapes.txt with a shape for every trip
All 14007 trips have a shape in shapes.txt.
- Meets Fare data published, or the service marked fare-free
Fare data is published.
- Correctness 76 / 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 60 / 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.
