Methodology and Data Notes
- Progress is measured against the 2010-14 average baseline set in the Mayor's Transport Strategy. Baselines are rounded to whole numbers, while percentages use unrounded figures.
- Modal risk rates divide casualty numbers by journeys from Travel in London 2023. The document gives a motorcycle fatality risk of 0.18 per million journeys in 2022.
- Self-reported casualties made up 42 per cent of casualties recorded in London in 2023.
- The factsheet lists corrections to errors identified after publication.
