Thank you for your request received by Transport for London (TfL) on 7 April 2017 asking for information about bus performance.

Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. I can confirm that we do hold the information you require.

Please see the attached zip files which contain the latest 13 finalised performance periods. For Low Frequency routes we record the percentage late. The percentage not running can be calculated from the on-time, early and late figures.

Notes:

Only data scheduled/actual between 05:00:00 and 23:59:59 is included for "Day" routes statistics.

Only data scheduled/actual between 00:00:00 and 04:59:59 is included for "Night" routes statistics.
