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 v1.3, validator 8.0.1.

Checked for changes 30 hours ago; last changed 1 days ago.

Measured 4 of 4 score categories from the feed URL on file (publisher not verified).

How we measured this

Confidence in this measurement: high.

  • All four score categories were measured this run.
  • Realtime was sampled in one bounded window of 9 snapshots.
  • The feed was downloaded from the configured feed URL. Publisher ownership of that URL is not verified.

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

225 of 225 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 in its category

Fix 02

Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out.

2 of 4 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.

⏱ A vendor data-mapping question.worth about +18 points in its category

Fix 03

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

120 of 120 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

⏱ A default or per-trip field in your export.worth about +15 points in its category

How to make and check these changes

Check the result on the published feed. Read the guide, make the change in your tool, and use the next comparable run to see whether the finding is still reported. Only an action or ticket record can attribute who made the change.

  1. Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. · Read the fix guide for scorecard_wheelchair_boarding_unknown

    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. See this feed's finding-clearance log.

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 1570 days.
Published accessibility data
Accessibility information is stated for 0% of stops and 0% of trips. This measures published data, not whether stops or vehicles are physically usable.
Fare information
No fare information is published in the feed.
Realtime information
Live-arrival data covered 50% of scheduled trips in the sampled window.

Important: This does not rate service reliability. Riders should confirm current service alerts, fares, and accessibility accommodations with the transit operator before traveling.

You may not control the GTFS export yourself. Copy this and send it to whoever runs your scheduling software export. It names each fix with the validator notice and a guide link.

Score by category

Correctness93.0 / 100

Freshness100.0 / 100

Service data covers the next 1570 days.

Rider experience45.0 / 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

  • 6 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (400, 500, 200, 100, 600, and more).

    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.

  • 217 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Goodrich Blvd & Olympic Blvd (SB)", "Union Pacific Ave & Goodrich Blvd", "Eastern Ave & Everington St", and more).

    Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.

Everything we checked

9 findings, ordered by severity.

Show every finding
  • Warning225 instances

    225 of 225 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 for scorecard_wheelchair_boarding_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning120 instances

    120 of 120 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 for scorecard_wheelchair_accessible_unknown · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning120 instances

    Some live predictions are more than 30 minutes away from the schedule.

    Differences that large usually mean predictions are keyed to the wrong trips, not that buses are that late.

    Fix: Spot-check the flagged predictions against what buses actually did; raise trip-matching with your AVL vendor. (A vendor data-mapping question.)

    Finding code: scorecard_rt_predictions_implausible

  • Warning7 instances

    Some route long names repeat the route's short name inside them.

    Apps show both names together, so riders see the number twice, like '5 5 Downtown'.

    Fix: Drop the short name from route_long_name and keep the long name descriptive, like 'Downtown via 5th Ave'. (One field per flagged route.)

    Finding code: route_long_name_contains_short_name · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning4 instances

    4 of 9 sampled vehicle positions were far from their assigned route (worst: 712 m).

    A bus shown off its route usually means a wrong trip assignment; riders watch their bus drive the wrong streets.

    Fix: Ask your AVL vendor to check vehicle-to-trip assignments for the flagged trips. (A vendor support ticket with the trip ids attached.)

    Finding code: scorecard_rt_vehicles_off_route

  • Warning2 instances

    2 of 4 trips scheduled during the sampling window had no live predictions.

    Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.

    Fix: Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out. (A vendor data-mapping question.)

    Finding code: scorecard_rt_trip_coverage · Read the fix guide for scorecard_rt_trip_coverage · See GTFS-Realtime reference (opens the GTFS-Realtime reference on an external site)

  • Warning1 instance

    The feed contains no fare information.

    Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

    Fix: Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead. (A small file for most flat-fare systems.)

    Finding code: scorecard_no_fare_data · Read the fix guide for scorecard_no_fare_data · See GTFS Best Practices (opens GTFS Best Practices on an external site)

  • Info3 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 for unknown_file · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Info2 instances

    Service extends far in the future (flagged by the MobilityData validator).

    See the linked rule for what this affects.

    Fix: Review the rule documentation for 'service_extends_far_in_the_future' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

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 1570 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 120 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

One requirement remains for this feed to earn the conformance mark. 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 Met
Service data covers the next 1570 days.
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 200 checks in the 31 days to 2026-09-15, with 0s median lag.

Sampled on a schedule between full scores, so this tracks uptime and freshness over time rather than at a single moment. The window ends at the newest observation, which is not always today: if the monitor stops, this window stops with it.

Live predictions vs schedule

Arrival predictions ran a median 260s early versus the schedule, and stayed within 15370s nine times in ten. They were on time (about a minute early to five late) 12.5% of the time. 66.7% of reported vehicle positions sat on or near the published route shape.

From the last full realtime sample: how far live arrival predictions sat from the schedule, and whether vehicle positions fell on the route. These feed the realtime score; they change no other category.

Clears the Google and Apple Maps four-week coverage bar. This feed has 1568 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.

The published guideline for this jurisdiction 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 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/commerce-municipal-bus-lines/2026-09-13.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 2026-09-13. 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.
