TfL Network Demand: Average Daily Journeys

Description

Monthly averages of TfL's reported daily journey counts for London's bus and Tube networks, split by mode and UK business-day status. The average is calculated over the daily observations in each month and group; it is not a monthly total.

Usage

transit_london_avgs

Format

A tibble with monthly observations:

date_month

First day of the calendar month (Date).

transit_mode

Transit mode: "bus" or "tube".

is_business_day

1 for a UK business day and 0 for a weekend or UK holiday.

avg_daily_journeys

Arithmetic mean of the reported daily journey counts for the month, mode, and business-day group.

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.
