Definition
- Definition
- The number of connected official operator notices whose source-published active interval is active at the time of the snapshot.
- Formula
- COUNT(notices where published start ≤ now and published end is absent or > now), after source parsing and catalogue deduplication.
- Units
- official notices
- Population
- Connected official operator notices after source parsing and catalogue deduplication.
- Measurement window
- Point-in-time snapshot evaluated against each notice’s source-published active interval.
- Coverage
- OC Transpo and STO official notice sources, with each source’s availability and freshness attached.
- Publication eligibility
- Only notices whose published start is at or before the snapshot and whose end is absent or later. Planned, expired and unknown-timing notices remain separate.
- Scope
- The current connected OC Transpo official notice source and STO GTFS-Realtime alert source. Source availability and freshness are reported with the count.
- What this number can support
- Count of source records, not a standardized amount of service lost or rider impact. Regional completeness is withheld when a required source is stale or unavailable.

Exclusions
- Planned, expired, and unknown-timing notices are not counted as active. Detected operating conditions and rider reports remain separate.
- The count is withheld as a complete regional burden when any required operator source is unavailable or stale.
Uncertainty and interpretation
- Operators choose notice granularity and affected-entity detail, so one notice is not a standardized unit of rider impact or service lost.
