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

التعريف

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

الصيغة

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.

الوحدات

percent of judged pairs, with the count of pairs

الفئة المشمولة

Pairs of buses on the same route and direction that arrived one after the other at the same stop, from settled final predictions.

نافذة القياس

The 28 most recent completed service days, by calendar date in Ottawa.

التغطية

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.

أهلية النشر

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.

النطاق

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).

ما الذي يمكن أن يدعمه هذا الرقم

A high share means buses often come together and then leave a longer wait behind them. It is not a count of late buses.
