Sources and identifiers

Exclusions

  • 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.

Uncertainty and interpretation

  • 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.
