A stop’s record is counted from the buses that called there in the last 30 days.
This is how often buses were on time at this stop, hour by hour, and what we can say about why they were not.
What we count
- Every time a bus was due at this stop in the last 30 days, we judged it against the timetable. On time means from one minute early to five minutes late.
- A trip that never came counts as a miss. A call we could not judge is left out. Only days we captured in full are counted, and the page says how many.
The hour chart and the weak window
- The chart shows weekdays only. An hour with too few judged calls shows no bar and says it is not measured yet.
- The weakest window is the lowest short run of hours in a row, with enough judged calls between them. Worst and best route each need enough judged calls.
The main cause
- The main cause is explained, not measured. A rule-based classifier looks for patterns in this stop’s own counts and names a cause only when its tests pass with at least medium confidence.
- When the evidence does not support a cause, the page says so. We never name one by guessing.
What is left out
- Only timetable timepoints are stored. A stop that is not one has no record, and the page says it is not measured yet. A stop with too few judged calls gets no share and no grade.
数字の出どころ
