The arithmetic mean delay of selected final provider predictions; negative values are early and positive values are late.
- 定義
- The arithmetic mean delay of selected final provider predictions; negative values are early and positive values are late.
- 公式
- AVG(settled delay seconds) for the route and published window.
- 單位
- seconds, displayed in minutes
- 對象群體
- The same selected final provider predictions used by the on-time percentage.
- 測量期間
- Rolling 30-day route-health window.
- 涵蓋範圍
- Matched published predictions only; each included settled final provider prediction has equal weight.
- 發布資格
- Regular comparable bus routes with publishable final provider-prediction evidence; excluded records follow the prediction-settlement method.
- 範圍
- Each route’s settled final provider predictions in the rolling 30-day route-health window.
- 這個數字可以說明什麼
- The mean signed schedule difference. Early and late values can offset each other, so it must be read beside on-time share and the upper-tail delay.

The final provider-prediction calculation is implemented in this source candidate. Public production verification for this corrected version is still not recorded.
排除項目
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.
不確定性與解讀
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.
