Heads-up: Days until the service window ends dropped by 26749 between 2026-10-06 and 2026-10-07, but only 1 day(s) passed. The feed's calendar appears to have moved backward, which can happen when an older export is republished. Worth confirming the latest export is the one being served. (checked 2026-10-07). This can be a brief vendor export glitch; watch the next update before acting.

Checked for changes 32 minutes ago; last changed 12 hours 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.

About this feed

Mountain Line Transit’s published feed lists 12 bus routes, 1,509 scheduled trips and 191 stops. Its service dates run from 2026-10-06 through 2026-10-07. It publishes realtime trip updates, vehicle positions and service alerts; when we checked, all of them answered. The published file last changed on 2026-10-07.

Top things to fix

Fix 01

Re-export the feed with a calendar that reaches further out. Set feed_end_date in feed_info.txt past your next service change.Likely your export tool

Service data ended 0 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.

This one is about the feed as a whole, so there is no share of it to count.

⏱ Usually one export setting; export on a schedule so it never lapses again.worth about +100 points in its category

Fix 02

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

191 of 191 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.

Fixing this covers all 191 stops in the feed.

⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 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

1509 of 1509 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

Fixing this covers all 1,509 trips in the feed.

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

Riders and need behind these fixes

  • This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
  • Arizona as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-05.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.

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 today.
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 93.3% 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.

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

  • 131 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).

Show every finding
  • Error1 instance

    Service data ended 0 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. Set feed_end_date in feed_info.txt past your next service change. (Usually one export setting; export on a schedule so it never lapses again.)

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

  • Warning1509 instances

    1509 of 1509 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)

  • Warning542 instances

    542 of 1509 trips have no headsign, the text that tells riders where the bus is going. A trip counts when it has trip_headsign or a stop_headsign at every stop.

    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 for scorecard_missing_headsigns · See GTFS Best Practices (opens GTFS Best Practices on an external site)

  • Warning191 instances

    191 of 191 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)

  • Warning134 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 for trip_distance_exceeds_shape_distance_below_threshold · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning9 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 for equal_shape_distance_same_coordinates · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning9 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 for stop_too_far_from_shape_using_user_distance · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning7 instances

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

  • Warning7 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 for stop_without_stop_time · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning6 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)

  • Warning2 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)

  • Warning2 instances

    Same name and description for route (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

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

  • 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 for feed_expiration_date7_days · See MobilityData GTFS Validator rules (opens the validator rules on an external site)

  • Warning1 instance

    Route short name too long (flagged by the MobilityData validator).

    See the linked rule for what this affects.

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

    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.)

  • 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.)

  • Warning1 instance

    1 of 15 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.)

  • 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.)

NTD GTFS readiness Not ready

Resolve this before you certify on the D-10. Service data expired 0 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 0 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) 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 1509 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

Two requirements remain for this feed to earn the conformance mark. Service data expired 0 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 0 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.

Can riders use it?

Checks beyond structural validation: places where the feed is valid but a rider still could not travel.

  • 7 of 191 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.

Realtime reliability

The realtime feed responded on 100.0% of 200 checks in the 25 days to 2026-10-07, 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 15s late versus the schedule, and stayed within 307s nine times in ten. They were on time (about a minute early to five late) 70.8% of the time. 96.0% 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.

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 42 / 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 40 / 100
GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
Realtime quality 97 / 100
GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.
