Versions

Transitland archives a new version of this feed whenever a fetch finds new contents. The latest version is the newest, and Transitland APIs serve the active version.

Each row is a version, newest first, and each square one week of its trips: their total trip hours, shaded as a share of a peak week across these versions, 117,019 trip hours, the 90th percentile of weeks with trips from 2026-01-05 to 2027-01-03. A version's row runs from its first date with trips, or its fetch if earlier, to its last, and 4 weeks past each end.
