Guardian visualises London buses' slowdown

newsSep 23, 20263266

The Guardian published an interactive visualisation showing London buses are slowing, becoming less reliable and carrying fewer passengers. Analysis of Transport for London data found the network average speed in 2025-26 was 9.18 mph, the lowest since comparable records began in 2013-14 and down 4.8% over that period. Passenger journeys have fallen by more than 300 million a year, or about 16% since 2013, with annual trips dropping from consistently over 2 billion in 2010, 19 to 1.8 billion in 2024. On high-frequency routes, passengers now wait 22% longer than scheduled, up from 18% in 2018, and the total distance travelled by TfL buses has declined from an average of 487 million km a year pre-2019 to roughly 460 million km over the past three years. Transport for London-cited research suggests a 10% fall in bus speed causes a 6% drop in demand, and the Confederation of Passenger Transport estimates a 10% speed increase would add £70m in fares and cut operating costs by £214m. London mayor Sadiq Khan warned lack of reliability is driving people away, industry figures warned of a "vicious circle of decline," and the piece notes similar slowdowns in Paris, Brussels and Lisbon. The Guardian highlights that slower, truncated services risk route and frequency cuts and that delays disproportionately affect poorer Londoners who rely on buses for shift work and lower-cost travel.
