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 v1.4, validator 8.0.1.
Checked for changes 3 hours ago; last changed 10 days ago.
Measured 3 of 4 score categories from the official feed URL on file.
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 official feed URL on file.
Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.

Top things to fix
Re-export with a validity window that reaches at least 60 days out.Likely your export tool
Service data runs out in 10 day(s). When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.
This one is about the feed as a whole, so there is no share of it to count.
⏱ One export setting.worth about +70 points in its category
Review the rule documentation for 'block_trips_with_overlapping_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Block trips with overlapping stop times (flagged by the MobilityData validator). See the linked rule for what this affects.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.
⏱ Varies.worth about +12 points in its category
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
1614 of 1614 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 1,614 stops in the feed.
⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 points in its category
Riders and need behind these fixes
- Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
- The served-area need overlays cover the United States and Canada, so none of them applies to this feed.
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 in 10 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
- 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 3 kinds of issue across 298 instances (1 error, 297 warning, 0 informational).
Service data runs out in 10 day(s). Publish an updated feed soon or riders will lose trip planning.
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.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.

- Error1 instance
Block trips with overlapping stop times (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'block_trips_with_overlapping_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Finding code: block_trips_with_overlapping_stop_times · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning6667 instances
6667 of 6667 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)
- Warning1614 instances
1614 of 1614 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)
- Warning296 instances
Some service calendars have no days of the week switched on.
Trips tied to these calendars never run; they are dead data that can mask real schedule problems.
Fix: Delete the empty calendars or set their service days. (A few minutes in your scheduling software.)
Finding code: service_has_no_active_day_of_the_week · Read the fix guide for service_has_no_active_day_of_the_week · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
A file GTFS asks for (usually feed_info.txt) is missing.
feed_info.txt tells apps who publishes the feed and when it expires; without it nobody is warned before data goes stale.
Fix: Add feed_info.txt with publisher name, URL, language, and feed_start_date/feed_end_date. (One small file, set once in export settings.)
Finding code: missing_recommended_file · Read the fix guide for missing_recommended_file · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
Service data runs out in 10 day(s).
When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.
Fix: Re-export with a validity window that reaches at least 60 days out. (One export setting.)
Finding code: scorecard_feed_expiring_soon · Read the fix guide for scorecard_feed_expiring_soon · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Warning1 instance
feed_info.txt is missing its start/end dates (the file itself is absent)
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 for scorecard_missing_feed_info_dates · 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 for scorecard_no_fare_data · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Info1 instance
feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).
App makers and state data programs have nobody to email when they spot a problem. Small errors then sit in the feed for months.
Fix: Add feed_contact_email to feed_info.txt. (One field.)
Finding code: scorecard_no_feed_contact · Read the fix guide for scorecard_no_feed_contact · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
Conformance mark Not yet
This feed does not meet the conformance requirements yet. Here is what the mark needs: 1 validator error to resolve. Service data runs out in 10 days; renew to qualify. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
- Valid Not yet
- 1 validator error to resolve.
- Current Not yet
- Service data runs out in 10 days; renew to qualify.
- 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.
At risk for the Google and Apple Maps four-week coverage bar. This feed has 9 days of service left. Maps needs at least four weeks (28 days) of upcoming service, so your agency will fall out of trip planners soon. Re-export with a longer calendar. The feed also carries 1 validator error, the other thing Maps checks at onboarding; the findings below name each fix.
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. Read the full standards crosswalk.
- 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.
- Freshness 2 / 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.
- Rider experience 38 / 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.

Cite this record
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/reading-buses/2026-10-15.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 2026-10-15. 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.
