The share of back-to-back buses on a route that arrived much closer together than the timetable planned for those same two trips.

Kahulugan
The share of back-to-back buses on a route that arrived much closer together than the timetable planned for those same two trips.
Pormula
At each stop, buses of one route and direction are put in the order they arrived. For each pair, the observed gap is compared with the scheduled gap between the same two trips. Bunched: observed gap under 0.25 times the scheduled gap. Long gap: over 1.75 times. Share = bunched pairs divided by judged pairs.
Yunit
percent of judged pairs, with the count of pairs
Populasyon
Pairs of buses on the same route and direction that arrived one after the other at the same stop, 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
A pair is judged only when the timetable planned 2 to 30 minutes between those two trips. A route needs at least 30 judged pairs before a share is shown.
Saklaw
Every bus route with judged pairs, by hour band: early 4 to 6, morning rush 6 to 9, midday 9 to 15, afternoon rush 15 to 18, evening 18 to 22, night 22 to 4 (Ottawa time).
Ano ang masusuportahan ng numerong ito
A high share means buses often come together and then leave a longer wait behind them. It is not a count of late buses.

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.

Comparing each pair with its own planned gap means an unseen bus in between, or a bus passing another, does not create a false bunch.

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.
