Action Vision Zero campaigners in London were given an update on 20mph sped limits in London. This presentation included status of London Boroughs, TfL roads and enforcement.

New data from Transport for London echoes what 20’s Plenty have been finding in recent 20mph implementations - that speed reductions on major and faster roads are resulting in substantial reductions in speeds and casualties for vulnerable road user casualties. TfL has just published research into the impact of the introduction of 20mph limits across a range of sites on the roads that it controls (typically London's arterial roads - the "Red Routes") which shows that, after speed limits were lowered, collisions involving a vulnerable road user have decreased by 36% (from 453 to 290), while collisions resulting in death or serious injury have decreased by 25% (from 94 to 71). The number of collisions involving people walking have decreased by 63% (from 124 to 46).
