New data released by Transport for London from 1 May 2020 to 30 June 2022 shows that there was a clear reduction in the number of casualties on roads with 20mph limits, even when accounting for the impact of the pandemic:
- Number of collisions has reduced by 25 per cent (from 406 to 304)
- Collisions resulting in death or serious injury have reduced by 25 per cent (from 94 to 71)
- Collisions involving vulnerable road users have decreased by 36 per cent (from 453 to 290)
- Collisions involving people walking have decreased by 63 per cent (from 124 to 46)
Lowering speeds is crucial to eliminating deaths and serious injuries. In London, currently over half of the roads have a 20mph speed limit, of which almost 110km is on TfL’s network. TfL is committed to expanding its lowering speed limits programme so more areas across London can benefit from safe speeds. They are now working to lower speeds on 220km of its roads by 2024 in inner and outer London and plans to introduce a new 20mph speed limit on over 28km of roads in Camden, Islington, Hackney, Tower Hamlets and Haringey in March 2023.
