Coverage overview.
How the public transit feeds in this site's current coverage are changing and whether the comparable covered corpus is getting better. This is not a census of any country or of the world. An absent scorecard is simply not covered yet.
Absolute score rankings and individual percentiles are not published. Named changes compare a feed only with its own prior check when the rubric, scoring profile, validator, and measured category set are unchanged. Corpus aggregates use rubric 1.4, scoring profile gtfs-scorecard-1.4, MobilityData gtfs-validator 8.0.1, reader archive profile raw-v1, and measured categories Correctness, Freshness, Rider experience; records with unresolved duplicate identities are excluded.
Feeds with measured realtime are not in this average. 251 feeds were scored on four categories this run, and a four-category score is not the same measurement as a three-category one. Their realtime results are on the realtime page. A feed leaves this average by publishing realtime, not by getting worse.

Covered-corpus average score
By date
| Date | Avg score | Feeds | Expired |
|---|---|---|---|
| 2026-10-08 | 70.3 | 1926 | 4.7% |
| 2026-10-07 | 70.2 | 1926 | 4.8% |
The series carries each agency's most recent score forward to each date and averages, so it is smooth even though agencies are checked on different days. It never changes a grade. The same data is at the trend API (trend.json).
In plain words: this page tracks the covered corpus at once, not any single agency. The most common problems page names the recurring fixes behind these numbers. Writing about this data? Start with the reporter's page.
Following a group of agencies rather than one? The program rollups group these same numbers by program. A program can collect that group's board reports into one archive, with prices on that page. Scoring is free for every agency, and each agency keeps a free, printable board one-pager on its own page. A purchase buys no influence over grades, methodology, or which agencies are listed.
