- Metodologia dei dati
- On-time percentage
The share of selected final provider predictions no more than five minutes early or late relative to schedule; arrivals are not independently measured.
- Definizione
- The share of selected final provider predictions no more than five minutes early or late relative to schedule; arrivals are not independently measured.
- Formula
- 100 × COUNT(|settled prediction delay seconds| ≤ 300) ÷ COUNT(settled final provider predictions), rounded to one decimal place.
- Unità
- percent of selected final feed predictions
- Popolazione
- One last eligible provider prediction per scheduled trip, stop and Toronto calendar date; no independently measured arrival.
- Periodo di misurazione
- Route summaries: rolling 30 days. Route-hour evidence: recent 14-day scan.
- Copertura
- Matched published predictions only. Numerator and denominator describe selected final feed predictions, not measured arrivals or all scheduled or operated trips.
- Idoneità alla pubblicazione
- Regular comparable bus routes; a route-hour needs at least 100 observations across at least three service days. Rail and purpose-specific routes are excluded from ordinary rankings.
- Ambito
- Route summaries use a rolling 30-day window. Recurring route-hour evidence uses the recent 14-day scan and is published only with at least 100 observations over at least three service days.
- Cosa può sostenere questo numero
- Schedule difference in final eligible feed predictions, not independently measured punctuality. It is not OC Transpo’s 99.5% service-delivery target, a cancellation rate, or proof that every scheduled trip ran.

- Produzione pubblica
- La versione corretta della metrica è implementata nel codice sorgente. La messa in produzione pubblica e la verifica non sono registrate.
Legga lo stato prima di citare questo numero.
The final provider-prediction calculation is implemented in this source candidate. Public production verification for this corrected version is still not recorded.
Esclusioni
Predictions more than ten minutes before the scheduled arrival are excluded, and delays outside ±90 minutes are removed as timetable-wrap outliers.
OC Transpo rail is excluded because the operator does not publish realtime rail observations in the feed used by this method.
Incertezza e interpretazione
The result describes matched published predictions, not every operated trip. Feed gaps and trip-matching limits can reduce coverage.
Current network evidence is recomputed and is not stored here as an immutable historical snapshot.

Il metodo corretto conserva l'ultima previsione entro dieci minuti da ogni arrivo e usa una finestra di cinque minuti su entrambi i lati. | In attesa del verificatore indipendente indicato. Non risulta registrata alcuna prova di approvazione. | In attesa: non sono registrati un identificativo di rilascio in produzione né un'ora di verifica. |
