Tuyến 687: Merivale H.S ⇄ Merivale Gardens

Estimated: this is worked out from final predictions, not from seeing each bus.

Cách chúng tôi tính

1. We pair buses on the same route and direction that arrive one after the other at the same stop.
2. We judge a pair only when the timetable planned a gap between them, as the method page defines it.
3. A pair counts as bunched as the method page defines it.
4. The share is the bunched pairs over the judged pairs, for the latest completed service days. A route with too few judged pairs shows no share.

Worked example

Mức độ chắc chắn của chúng tôi

This is an estimate: it rests on predictions, not on independently measured arrivals. It is not a count of late buses.

Limits, and what would change it

• A high share means buses come together and leave a long wait behind, not that they are late.
• Only completed days count.
• A pair the timetable did not plan a gap for is not judged.
