Prediction-to-timetable match coverage
- Version
- realtime-prediction-timetable-match-v1
- ID
- network-quality:prediction-timetable-match-coverage
Definition
- Definition
- The share of published realtime prediction points that can be joined to an official scheduled trip and stop time.
- Formula
- 100 × matched prediction points ÷ all prediction points. The current value uses the trailing 30 minutes; the historical quality window aggregates completed service days.
- Units
- percent of realtime prediction points
- Scope
- The connected OC Transpo and STO realtime prediction observations and the matching currently imported static GTFS timetable.

Exclusions
- This is an evidence-pipeline quality measure, not a punctuality, cancellation, or operated-service score.
- A prediction that cannot be joined is not treated as proof that the associated trip or stop service did not operate.
Uncertainty and interpretation
- Static and realtime identifiers can diverge during schedule transitions, partial feed failures, or operator changes; those gaps reduce coverage without describing rider outcomes.
