20mph Limit Reduces London Road Deaths

The 20mph speed limit imposed on London streets has brought down the road fatalities by 40%, according to a new study.

The number of casualties has dropped by 41.9%, pedestrian injuries have come down by just under a third and cycling casualties have dropped by 16.9%.

In particular, the move has saved the lives of young children with the numbers of children killed or seriously injured halved in the zoned areas, says the study conducted by the London School of Hygiene & Tropical Medicine.

Over the last two decades, many 20mph speed limit zones has been established in London using speed limit signs and traffic-calming measures such as road humps and chicanes.
