Compared with TfL's own figures
| Quarter | TfL | Ours |
|---|---|---|
| 2025/26 Q313 Sept – 2 Jan 2026 | 80% on time | no figure |
| 2026/27 Q11 Apr – 26 Jun 2026 | 88% on time | no figure |
TfL's figures come from its own tracking equipment and its own timetable; mine are computed from the buses' public position feed. They are the same calculation on independent data, so they should broadly agree and move together rather than match exactly.
About this data
- Data collected, week ending 17 October 2026
- 100% of the week. This is the share of the week for which we hold bus location data at all, across the whole of London rather than for this route. A week under 60% is not published; under 90% it is marked as thin.
- Departures observed
- Princess Royal University Hospital: 200 departures seen
- How it is measured
- Every day, 05:00–23:59. On time means leaving no more than 2.5 minutes early or 5 minutes late. A day with less than four hours of data collected shows no daily figure. How these figures are made.
