How is service doing

Cancelled trips, counted

Retained operator cancellation notices from the last four weeks; the counts below use the published timetable and available vehicle observations. Trips with no notice and no bus sighting are counted separately.

Two problems, side by side

Do not add these together. One is what the operator said. The other is what we measured.

OC Transpo publishes reasons only as weekly totals for the whole network, not per trip. They are shown on the explainer page, kept apart from these counts. See OC Transpo’s reasons

OC Transpo

Service days Wed, Sep 9 to Tue, Oct 6. Today is not included until it ends.

Scheduled trips with cancellation notices: 1,405; Scheduled trips marked cancelled without qualifying later matching vehicle observations in our archive. This does not prove the trip did not operate.
On a typical day: 53
Worst day: 101; Wed, Sep 23
All cancellation notices: 5,499; Every trip with a retained notice, including trips with qualifying later matching vehicle observations. Not a count of cancelled trips.

Not counted: 2,123 trips with qualifying later matching vehicle observations and 1,372 for trips not in that day’s timetable. 1 partial-capture day not counted.

By day

The dark bar is the count. The light bar is all notices. A day marked “unknown” had no notice we could check, so it is not shown as zero. A day marked “partly captured” is unknown too: we missed most bus positions that day, so we cannot reliably check later vehicle observations.

Routes with the most cancellations

Counted cancellations per route over the four weeks. Busy routes run more trips, so they can have more cancellations.

School routes and regular routes

23 on school routes, 1,382 on regular routes.

OC Transpo school routes are numbered 600 to 699. They run a few trips a day at bell times. A whole school day can be cancelled at once, which makes one day look very bad.

Week by week

Counted cancellations for each of the last four weeks, oldest first.

Did not come: no bus seen, no notice

A separate measure. These trips were in the timetable and no bus was ever seen on them, but the operator posted no cancellation.

Service days Wed, Sep 30 to Tue, Oct 6 (last seven days).

Did not come: 287; 287 of 31,039 trips we could check (0.9%).
Not seen, but cancelled: 197; No bus was seen and the operator did post a notice. These belong with cancellations above, not here.
We did not see this bus: 7,447; Trips where the live data was too thin to tell, or the trip numbers did not match. Unknown, left out.

A bus can run with its tracker off, or logged on the wrong trip. So a trip here may have run. It needs checking. It is not proof. Trains are not included: OC Transpo publishes no train positions.
