What riders need to know about route 99
Current operator facts and historical observations are kept separate. Missing data is highlighted, but it is not automatically called a cancelled trip or no-show.
Current evidence band

83.4% within ±5 min · 21,491 settled arrivals
Service purpose
Conventional all-stop service
Schedule adherence is assessed at settled arrivals. The visible attention bands are: strong at 80% or more within ±5 minutes; watch at 65–79.9%; needs attention below 65%. At least 200 arrivals are required.

Upcoming route-origin departures in the current four-hour board; this is not a historical cancellation rate.
A skipped origin is kept separate from a cancelled trip. Either claim appears only from a current healthy provider relationship.
184 of 478 scheduled trips lacked a matched vehicle position over 7 service days (61.5% observed). These are investigation candidates, not confirmed no-shows.
95% were no later than 8.1 min after schedule in this cohort.
No route-level high-frequency regularity result meets the evidence gate. This does not mean gaps did not occur.
The public vehicle feed does not provide dependable passenger loads or pass-up events. Rider reports identify where to investigate, but are not turned into a rate.
A notice may explain a change, but it is not a historical short-turn count. Otranspo does not infer an unannounced route change from a missing position.
Recurring problem periods
Hours below 70% within ±5 minutes on at least three service days are surfaced for action. They describe timetable deviation, not proven service failure.
No recurring below-70% hour is established in the currently published route cohorts.
Evidence-backed problem locations
No route-by-stop historical cohort meets the publication contract yet. The route map below highlights current notice-affected stops and live buses, but rider reports are not turned into hotspot claims.
How claims earn confidence
- Official current feed: explicit cancellations, skipped stops and active notices.
- Matched observations: settled predictions and vehicle positions tied to the official schedule.
- Official timetable: what was scheduled, kept distinct from what was observed.
- Rider and operator reports: valuable leads for routes, times and places to investigate—not numeric proof by themselves.

What is happening on this route
Timetable, vehicle and notice evidence are kept separate so a missing live feed is never presented as no service.

Planned changes
The planned-change register is unavailable. No planned change is confirmed or ruled out.
These are Otranspo register records, separate from operator alerts. A record is attached only when its route label identifies one operator; ambiguous OC Transpo/STO number matches are withheld.

Reliability evidence by published route cohort
This public route groups more than one official schedule record. Percentiles and observed weekday sets cannot be safely merged from published aggregates, so each matching evidence cohort remains separate.
Observed evidence cohort 99
Provisional results, published evidence
When is this route reliable?
Every hour below is backed by this route’s settled arrivals. “On time” means no more than five minutes early or late, so a bus that leaves very early counts as a failure for the waiting rider.

Patterns by hour (0)
Not enough arrivals yet to split this route by hour.
No repeated pattern below 70% is yet established across at least three service days.
Scheduled bus, but not observed in realtime
294 / 478 scheduled trips published at least one position across 7 service days (61.5%).
This is not a confirmed no-show. A missing position can mean a cancelled or missed bus, but it can also mean an unassigned trip ID or an operator-feed gap. Otranspo publishes the gap because it matters to riders while keeping the conclusion honest.
Method: last prediction within ten minutes of each arrival; one arrival per trip, stop and service date. Trip coverage: GTFS schedule compared with any GTFS-RT position carrying the same trip and local service date. Sources and limitations.

What is being shown
The current public route group, its published schedule variants and stop patterns, current operations, and matching observed reliability where available.
How it was produced
2 current GTFS route record variants are grouped by operator and public route number. Stop patterns remain tied to their published variant; aggregated reliability records are not merged into an invented percentile.
Evidence dates
- Computed or assembled
- Sample
- 21,491 settled arrivals across 1 matching reliability records.

Limits to keep in mind
- Schedule variants can apply on different dates. A grouped route is not a claim that every pattern operates today.
- Accessibility fields report only what the operator publishes; an unknown value is not confirmation of access.
