Checked for changes 72 minutes ago; last changed 33 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.
Top things to fix
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
196 of 203 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.

Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.Likely your export tool
181 of 181 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

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 153 days.
- Published accessibility data
- Accessibility information is stated for 3.4% of stops and 0% 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 5 kinds of issue across 116 instances (0 error, 66 warning, 50 informational).
Service data covers the next 153 days.
3% of stops state wheelchair accessibility (3% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is published.
3% of stops state accessibility (3% marked accessible). Reflects what the feed states, not verified physical usability.
2 accessibility depth signals
5 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (Red Line, Blue Line, 2, 4, 5).
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.
37 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Greenspot Blvd & Standford Way", "Greenway Dr & North Shore Dr", "Greenway Dr & Arbor Ln - Natures Inn", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.

Show every finding
- Warning196 instances
196 of 203 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)
- Warning181 instances
181 of 181 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)
- Warning65 instances
Some stops exist in the feed but no trip ever stops at them.
Riders may walk to a stop where no bus is scheduled to arrive.
Fix: Remove retired stops from the export, or add them back to the trips that should serve them. (A review pass in your scheduling software.)
Finding code: stop_without_stop_time · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning38 instances
38 of 181 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)
- Warning1 instance
Some trips serve fewer than two stops.
A trip with one stop can't be ridden; planners ignore it and it may signal an export problem.
Fix: Check the flagged trips in your scheduling software; remove them or restore their missing stops. (Worth a vendor question if it appears often.)
Finding code: unusable_trip · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
This feed describes flexible (demand-responsive) service but has no booking_rules.txt.
Riders can see the service area but not how or when to reserve a trip, so they can't actually use the service.
Fix: Add booking_rules.txt saying how far ahead and how to book (phone, app, or web). (A small file; one rule often covers the whole service.)
Finding code: scorecard_flex_no_booking_rules · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Info34 instances
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.)
Finding code: unknown_column · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info8 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)
- Info8 instances
The feed includes a file that is not part of the GTFS spec.
Apps ignore files they don't know, and a stray file can hide a misspelled standard file name.
Fix: Check the flagged file name for a typo of a standard GTFS file. Remove it if it is a vendor extra. (A quick look at the flagged file.)
Finding code: unknown_file · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
Beyond the grade
Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.
Flex zones are published but no booking_rules.txt is present.
Consider: Add booking_rules.txt with how far ahead and how to reserve (phone, app, or web).
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 153 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 Needs attention
- 180 of 181 trips have a shape; 1 do not. Fill in shapes.txt and trips.shape_id for the remaining trips so every trip has a path. Reduced, Rural, and Tribal NTD reporters need full coverage by Report Year 2026.
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 3% of stops and 0% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 153 days.
- Accessible Not yet
- States wheelchair access on 3% 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.
Can riders use it?
Checks beyond structural validation: places where the feed is valid but a rider still could not travel.
- 1 of 181 trips list fewer than two stops. A trip with one stop has no leg a rider can ride; trip planners can't route anyone on it, so the service effectively does not exist. Check your scheduling export: every trip should list each stop it calls at, in order, with times.
- 65 of 203 boardable stops are never served by any trip. Riders see these stops in apps and on the map but can never catch anything there, which erodes trust in the data. Remove stops no route serves, or add the trips that should call at them.
These do not change the grade. They catch trips with no rideable leg and stops no trip serves, the kind of gap a trip planner trips over.
Clears the Google and Apple Maps four-week coverage bar. This feed has 153 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 (4 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 3% of stops and 0% of trips.
- Gap shapes.txt with a shape for every trip
180 of 181 trips have a shape; 1 do not.
- Meets Fare data published, or the service marked fare-free
Fare data is published.
- Correctness 86 / 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 58 / 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.

The record below does not: it is the dated file this grade came from, published at https://gtfsscorecard.org/data/artifacts/mountain-transit/2026-08-01.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 2026-08-01. 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.
