Source
Transport for London (TfL), Network demand data, and the Network Demand Dashboard. The package distributes an aggregated and reshaped version of TfL's daily Journeys files and classifies dates with the UK business calendar. TfL's Transport Data Service terms require the attribution: Powered by TfL Open Data. This package is not affiliated with or endorsed by TfL.
Details
The business-day flag uses the QuantLib/UnitedKingdom calendar from
RQuantLib: 1 identifies a business day and 0 identifies a Saturday,
Sunday, or UK holiday. The underlying counts are derived from TfL's
ticketing system and should not be interpreted as an absolute measure of
passenger numbers or journeys made. They are approximate, rounded to the
nearest thousand, and exclude passengers who did not tap in or out.
The version bundled with trendseries covers daily source records from
2019-01-01 through 2025-12-27. December 2025 is therefore a partial month.
TfL may revise historical rows when its source files are refreshed.
