Observed reliability publishes after 20 weekdays of observation. The archive holds 8; 12 to go. The countdown is automatic — nobody flips it by hand.
How on-time is measured — and why the number fell
Until 4 August 2026 we counted every prediction the agency archived. A single arrival is predicted dozens of times, and 42.23% of those records carried a delay of exactly zero — not because the bus was on time, but because the agency republishes the timetable for a vehicle it has not yet located.
We now count one observation per arrival: the last prediction made within ten minutes of the scheduled time. Measured both ways over the same archive, that is 86.7% against 77.4%. The figure fell because the method was corrected, not because service got worse.
Scope: buses only. The agency publishes no realtime data for the O-Train, so no rail line appears in the archive at all. At 25 of the 61 stations, served by both bus and rail, the figure describes only part of what stops there.
Our data
Every City dataset we use is recorded in the registry with its licence, cadence and last import. The map’s Data panel renders that registry live.
