The share of back-to-back buses on a route that arrived much closer together than the timetable planned for those same two trips.
- تعریف
- The share of back-to-back buses on a route that arrived much closer together than the timetable planned for those same two trips.
- فورمول
- 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.
- واحدها
- percent of judged pairs, with the count of pairs
- جمعیت
- Pairs of buses on the same route and direction that arrived one after the other at the same stop, from settled final predictions.
- دورهٔ اندازهگیری
- The 28 most recent completed service days, by calendar date in Ottawa.
- پوشش
- 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.
- واجد شرایط بودن برای نشر
- 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.
- دامنه
- 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).
- این عدد چه چیزی را نشان داده میتواند
- A high share means buses often come together and then leave a longer wait behind them. It is not a count of late buses.

لطفاً پیش از ذکر این عدد، وضعیت آن را بخوانید.
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.
موارد مستثنا
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.
عدم قطعیت و تفسیر
Arrival times are the last prediction made no earlier than 10 minutes before the scheduled time, not a recorded door opening.
