Sort selected final predicted delays from least to greatest. This is the delay where about 5 predictions in 100 were equally late or later in the published route window.
- 定义
- Sort selected final predicted delays from least to greatest. This is the delay where about 5 predictions in 100 were equally late or later in the published route window.
- 公式
- PERCENTILE_DISC(0.95) ordered by settled delay seconds.
- 单位
- seconds, displayed in minutes
- 人群
- The same selected final provider predictions used by the on-time percentage.
- 测量时段
- Rolling 30-day route-health window.
- 覆盖范围
- Matched published predictions only; the discrete percentile selects a final predicted delay value.
- 发布资格
- Regular comparable bus routes with publishable final provider-prediction evidence; merged route variants with incompatible distributions withhold this percentile.
- 范围
- Each route’s settled final provider predictions in the rolling 30-day route-health window.
- 这个数字可以说明什么
- An upper-tail final-prediction schedule difference: about five selected predictions in one hundred were this late or later. This is not an independently measured arrival.

引用这个数字之前，请先阅读状态说明。
The final provider-prediction calculation is implemented in this source candidate. Public production verification for this corrected version is still not recorded.
排除项
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.
不确定性与解读
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.
