Route check
How route 644 is doing
A plain-language summary of the strongest evidence we have. We say when the data cannot answer a question.
Bottom line
We do not have enough evidence to rate this route yet.
Confidence in this summary: Still building
Problems to fix
These are repeated patterns, not one bad day or an unverified rider report.
No recurring problem time has cleared our evidence threshold yet.
Official notices cannot be confirmed right now.
Problem places
We do not yet have enough route-by-stop history to name a recurring problem stop. Rider reports are used as leads, not proof.
The questions riders ask
- Cancelled trips right now
- Cannot confirm right now
- Trips that may not have shown up
- No confirmed count yet
- Late service
- Not enough evidence yet
- Long gaps or bunching
- No route-level result meets the evidence threshold yet. This does not mean gaps did not happen.
Checks trips starting at route endpoints in the next 4 hours. This is not a historical cancellation rate.
The schedule-to-position check is unavailable, so we do not guess.
How this route is judged: Regular all-stop route
We compare observed arrivals with the official schedule. A result needs at least 200 arrivals. Within 5 minutes is the rider-facing target used here.
What this data cannot prove
The public feed does not provide dependable passenger counts or passed-up-rider events. A missing position does not by itself prove a cancellation, no-show, short turn or cause.
See the definitions, thresholds and evidence order
- Official current feed: explicit cancellations, skipped stops and active notices.
- Matched observations: vehicle positions and settled predictions tied to the official schedule.
- Official timetable: what was planned, kept separate from what was observed.
- Rider and operator reports: leads about routes, times and places to investigate—not numeric proof by themselves.

Fresh vehicle positions appear on the route below. A marker stops moving when the evidence runs out—we do not invent movement.
Route and live buses
The line is the official route. Dots show published stops, buses seen now and stops named in current notices.

The realtime prediction feed is unavailable or stale. Timetable times remain labelled as scheduled only.
Buses seen now
Current vehicle positions cannot be confirmed. No zero is shown.
Official notices
The operator notice feed is unavailable or stale, so no all-clear is claimed.
Planned changes
No safely matched planned change is recorded for this route.
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.

Data behind this result
This route has more than one official schedule record. We keep each record separate so the totals stay checkable and we do not invent a combined worst-case result.
Open any result below to see the hours, denominators, observed days, and position coverage behind it.
No reliability cohort can be safely matched to this public route. No representative schedule record is substituted.

Evidence behind this pageOpen the definition, method, sources, dates, coverage, and known limits.
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
1 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
- Sample
- No matching settled-arrival reliability sample is currently published for this public route.
- Coverage
- Published stop-pattern coverage is unavailable for this route.
- Method or data version
- last-prediction-within-ten-minutes-v1

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.
