Road injuries are among the leading causes of mortality and disability worldwide, disproportionately borne by poor pedestrians, particularly children and young adults.  Chris Grundy and his colleagues from the London School of Hygiene and Tropical Medicine investigate the effect of 20 mph (32 kph) speed zones on road casualties in London. They found that the introduction of 20 mph zones was associated with a 41.9% reduction in road casualties and that the percentage reduction was greatest in younger children and greater for the category of killed or seriously injured. In addition the researchers found that the areas adjacent to 20 mph zones, also had a reduction in casualties (8%) suggesting that there was no migration of casualties to nearby roads.
