Checked for changes 3 hours ago; last changed 16 hours ago.

Measured 4 of 4 score categories from the agency's own feed.

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 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

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

181 of 181 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

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

2753 of 2753 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

Fix 03

Add feed_info.txt with feed_start_date and feed_end_date to your export.Likely your export tool

feed_info.txt is missing its start/end dates Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.

⏱ Two fields, set once in export settings.worth about +15 points in its category

Rider view: what this feed publishes

A quick read of rider-facing information in this feed.

Schedule visibility
The feed states that service is published through 2099-12-31. This may be intentional or a placeholder; confirm current service with the transit operator.
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 80% 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.

Score by category

Correctness63.0 / 100

The MobilityData validator flagged 9 kinds of issue across 434 instances (0 error, 427 warning, 7 informational).

Freshness85.0 / 100

Service is published through 2099-12-31. It may be intentional, but confirm the end date before treating the feed as maintained.

Rider experience41.1 / 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

  • 3 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (4, 5, 66).

    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.

  • 130 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Route 66 / Thompson St (Mavrik) WB", "Route 66 / Railroad Springs Blvd WB", "Route 66 / Northwestern St (Hidden Hollow) WB", 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

15 findings, ordered by severity.

Show every finding
  • Warning2753 instances

    2753 of 2753 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)

  • Warning710 instances

    710 of 2753 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)

  • Warning398 instances

    On some trips the stop distances run a little past the end of the route line.

    The stop and shape distance values don't quite line up, so any math that uses them can drift.

    Fix: Re-generate shape_dist_traveled on export so stop and shape distances use the same units. (Usually an export-tool fix, not hand editing.)

    Finding code: trip_distance_exceeds_shape_distance_below_threshold · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning181 instances

    181 of 181 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)

  • Warning12 instances

    Some route lines list the same point twice in a row.

    Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.

    Fix: Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt. (Usually one export setting.)

    Finding code: equal_shape_distance_same_coordinates · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning7 instances

    Some stops sit far from the route line, going by the feed's own distance values.

    Trip planners may draw the route down the wrong streets or point riders to the wrong corner.

    Fix: Check the flagged stops' shape_dist_traveled against the route shape, and re-generate it on export if they disagree. (Usually an export-tool fix, not hand editing.)

    Finding code: stop_too_far_from_shape_using_user_distance · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning5 instances

    Some values have extra spaces at the start or end.

    A stray space can break a match, so a stop or route may fail to link across files.

    Fix: Trim leading and trailing spaces on export. The scorecard's auto-fixed copy already does this. (Usually one export setting.)

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

  • Warning3 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.)

    Finding code: expired_calendar · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning2 instances

    2 of 10 trips scheduled during the sampling window had no live predictions.

    Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

    Fix: Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs. (A vendor data-mapping question.)

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

  • Warning1 instance

    feed_info.txt does not state when this feed starts and ends.

    Without stated dates, apps can't warn anyone before your data goes stale; it just disappears one day.

    Fix: Fill in feed_start_date and feed_end_date in feed_info.txt. (Two fields, likely set once in your export settings.)

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

  • Warning1 instance

    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.)

    Finding code: missing_recommended_field · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning1 instance

    feed_info.txt is missing its start/end dates

    Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.

    Fix: Add feed_info.txt with feed_start_date and feed_end_date to your export. (Two fields, set once in export settings.)

    Finding code: scorecard_missing_feed_info_dates · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules 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 · See GTFS Best Practices (opens GTFS Best Practices on an external site)

  • Info4 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.)

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

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
The published window is current, but its service end date is unusually distant; confirm that date is intentional.
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 2753 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 0% of stops and 0% of trips; the mark needs 90% of each.

Valid Met
Passes validation with no errors.
Current Met
The published window is current, but its service end date is unusually distant; confirm that date is intentional.
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 over the last 34 days, 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.

Live predictions vs schedule

Arrival predictions ran a median 106s early versus the schedule, and stayed within 305s nine times in ten. They were on time (about a minute early to five late) 37.3% of the time. 95.7% 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 clears the four-week coverage window, but its service end date is unusually distant. Confirm that date is intentional before treating it as evidence of ongoing maintenance. 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.

Correctness 63 / 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 85 / 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 41 / 100
GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
Realtime quality 92 / 100
GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.
