Request ID: FOI-2778-2324 Date published: 27 November 2023
You asked
NB Requested data and methods are similar to those used in FOI request FOI-0842-2122[1]
Scope
Bus journey time on Croxted Road north, as calculated by combining data from the 3 and 201 bus, between the following stops:
Northbound (NB): Thurlow Park Road (WT) to Brockwell Park (H)
Southbound (SB): Brockwell Park (G) to Croxted Road / Thurlow Park Road (WF)
Data
- Daily iBus data for the following four time windows
• 7 June 2022 to 30 June 2022
• 7 September 2022 to 13 December 2022
• 6 June 2023 to 29 June 2023
• 6 September 2023 to 12 December 2023 (or the most recent available at time of processing)
- calculate average journey times by route for the above road sections. These journey times should exclude dwell times at stops.
- calculate this separately for the following 2 time periods
• AM = 08:00 to 09:15
• PM = 15:15 to 16:15
Calculating corridor averages
- Journey times should first be summarised by route (i.e. 3 vs 201), by taking the total journey time across stop-to-stop links along the corridor and dividing by the length of these links, to give a minutes per kilometre figure.
- Corridor level figures should then be found by taking a weighted average across the route level figures, weighted by the route frequency.
Data to be returned
An excel sheet similar to that in the ‘Data’ tab of Spreadsheet A provided in TfL FOI-0842-2122, except at the day level. Columns headings would be as follows, with first rows filled in as examples
Day Corridor Dir Time Avg Weighted JT (min/km)

07/09/2022 Croxted north NB PM
08/09/2022 Croxted north NB AM
