Scheduled trips with cancellation notices

—

No retained notice returned; this does not prove zero cancellations.

Trips needing investigation

0 of 30 trips with a usable feed window (0%) had no matching position.

These counts may overlap; do not add them. A missing position confirms neither cancellation nor a no-show.

30 with position · 0 to investigate · 0 excluded · 30 scheduled trips

Current feed. No explicit notice for this route in the current feed; this does not guarantee service. Observed: Nov 5, 2026, 10:00 a.m..

Coverage, exclusions and sources

0 scheduled trips were excluded from the position check for feed or identity gaps.

Published position coverage: 30 / 30 (100%). This is not a delivered-service rate. 7 service days in this source.

Timetables retained before the service day: 7 / 7 requested days · 0 missing days.

Historical calculation: Nov 5, 2026, 8:49 a.m.

Method: explicit provider notices, archived trip windows and retained timetables. Predictions and positions alone do not prove that a bus ran or was missed.

Predictions against the timetable

No comparable percentage published

This service purpose needs a different method. A general percentage could give a misleading picture.

Predictions in the source: 320
Weekdays with evidence: 18
Evidence window: Oct 7, 2026 – Nov 4, 2026

These are provider predictions, not independently measured arrivals. Missing evidence is not counted as on-time service.

Calculated: Nov 5, 2026

2 partial-capture days not counted.

What about time of day?

The general hourly comparison is not suitable for this service purpose. Source records remain available.

Improvement or decline requires comparable periods. This single result cannot establish a trend.

Buses arriving bunched

Last 28 days, October 8, 2026 to November 4, 2026: 26 days counted.

2 days left out because the live feed was only partly recorded or its trip numbers did not match the timetable: October 8, 2026, October 15, 2026.

Too few buses were measured to judge bunching: 0 pairs checked, 30 needed.

What this route needs

Median provider predictions are 4.2 min later than the timetable in 1 hours of the day.

Matched public positions cover 100% of scheduled trips. This is a lower bound on operated service, not an audited delivery result.

Scenario: 4 min more running time on 10 trips. The schedule-block model adds no buses; fleet and workforce feasibility are unverified.

Assumptions: published departure times, trip blocks and service pattern stay fixed while running time changes. A scheduler must test headways, transfers, recovery, fleet circulation, operator shifts, labour rules and cost before use.

Route check

How route 539 has been running

A short summary of what we know. We say so when we cannot answer a question.

Bottom line

We need to know where this express route picks people up before we can rate it.

Prediction sample size: Moderate sample

Based on 320 eligible provider predictions over 18 measured days, from Oct 7, 2026 to Nov 4, 2026.

Updated Nov 5, 2026, 9:32 a.m.

Where and when did predictions differ repeatedly?

These are repeated prediction-to-timetable differences, not independently measured service failures. They use the same eligible predictions as the result above, but group by stop rather than hour, so the lists need not match line for line.

Problem times are not ranked because this service needs a purpose-specific test.

No current official notice matches this route.

Prediction differences by stop

We do not yet have enough route-by-stop history to name a recurring problem stop. Rider reports are used as leads, not proof.

What riders want to know

Is any trip cancelled right now?: No trips start in the next 4 hoursChecks trips starting at route endpoints in the next 4 hours. This is not a historical cancellation rate.
Possible no-shows after checking feed gaps?: 0 of 30 checked trips need a closer look0 of 30 trips with enough public-feed evidence had no matching position over 7 days. 0 of 30 scheduled trips were excluded because the feed record was incomplete. These are cases to investigate, not confirmed no-shows.
How did provider predictions differ from the timetable?: Not enough evidence yet
What wait did provider predictions imply?: No route-level result meets the evidence threshold yet. This does not mean gaps did not happen.

Checksums let anyone verify which retained timetable produced the counts. A changed count does not identify a cause, cancellation, operator decision, or passenger impact.

How this route is judged: Express / commuter route

Inbound performance must be checked at pickup points. Early outbound running after pickups are finished is not treated like early service on a regular route.

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.

Provisional results, published evidence

Data behind this result

An ordinary on-time grade is not appropriate for this service without checking its purpose. The route check above explains the pickup, community-service or event evidence needed. You can still inspect the recorded trips and data gaps below.

Eligible predictions checked: 320
Weekdays with data: 18

Scheduled bus, but not observed in realtime

30 / 30 scheduled trips published at least one position across 5 service days (100.0%).

18:000 / 5 trips without a position100.0%

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.

Prediction check: the last eligible provider prediction no earlier than ten minutes before the scheduled arrival, counted once per trip, stop and scheduled Toronto calendar date. It is compared with the timetable, not an independently measured arrival. Trip-position check: the timetable kept before each service day, matched to recorded positions. Exact IDs are preferred; an OC timetable suffix is matched only to one trip on the same route and date with an overlapping time window. Missing timetables, ambiguous matches and feed gaps stay labelled; they are not confirmed no-shows. Sources and limitations.
