How fast buses actually moved between two consecutive timepoints of a route, next to the speed the timetable planned for the same segment.

Kahulugan
How fast buses actually moved between two consecutive timepoints of a route, next to the speed the timetable planned for the same segment.
Pormula
Segment ends are the stops the timetable marks as timepoints. When it marks every stop, the trip is cut about every 1 kilometre. Observed time = arrival at the end minus arrival at the start. Speed = distance times trips divided by total time, in kilometres per hour. Slow trip: took at least 1.5 times the scheduled time.
Yunit
kilometres per hour, with the count of trips
Populasyon
Trips that reached both ends of a segment between two consecutive timepoints, from settled final predictions.
Saklaw na panahon ng pagsukat
The 28 most recent completed service days, by calendar date in Ottawa.
Saklaw
Only days the daily rollup computed. Days with partial feed capture and days when the live trip numbers did not match the timetable are left out and listed.
Pagiging karapat-dapat na ilathala
Segments shorter than 300 metres or 1 minute are not measured. A segment needs at least 20 trips before a speed is shown.
Saklaw
Every bus route segment with enough trips, by the same hour bands as bunching.
Ano ang masusuportahan ng numerong ito
Compare the observed speed with the scheduled speed on the same segment. Distance is a straight line between stops, so both speeds are lower than the road speed.

Katayuan ng implementasyon

Posibleng pinagmulan
Naipatupad sa kandidatong ito ng pinagmulan.
Pampublikong produksyon
Hindi pa napatunayan nang independiyente ang bersyon ng sukatang ito sa pampublikong production deployment.

Basahin po ang katayuan bago banggitin ang numerong ito.

The daily calculation is implemented in this source candidate (worker rollup, migrations 0396 and 0407, method settled-reliability-patterns-daily-v2). Public production verification for this version is not yet recorded.

Mga hindi kasama

OC Transpo O-Train lines are left out: the operator publishes no live train positions, so their arrivals repeat the timetable.

Times over 4 times the schedule plus 10 minutes are treated as data errors and left out. A stop a trip visits twice is never a segment end.

Kawalang-katiyakan at pagpapakahulugan

Arrival times are the last prediction made no earlier than 10 minutes before the scheduled time, not a recorded door opening.

Distance is the straight line between stops along the trip, not the road, so speeds are lower than true road speeds. Use them to compare segments, not to check speed limits.
