20mph = Safer speed?

20mph limits being trialled in London have shown initial success!
British Medical Journal reports show road injuries have been reduced by more than 40% in these areas. In a comparison to figures from 1986 to 2006, casualties were reduced by 41% with deaths and serious injuries to children reduced by half. Pedestrian injuries were reduced by nearly a third and cycling casualties by nearly 17%. With the zones preventing about 203 casualties a year in the current zones alone. If these zones were increased the reductions would also follow.
In addition the areas adjacent to the zones benefited from an average reduction of 8%.
