"2005 study found that only 5% of pedestrians hit at 20mph were killed, compared to 50% hit at 30mph. Other studies have shown that a 1mph reduction in average traffic speed is associated with a 5%-6% drop in injury-causing collisions."
"There is evidence from across the world that vehicle speeds are one of the main reasons why people do not walk or cycle or do not allow their children to walk or cycle to school."
"However, in 20mph zones vehicles moved more smoothly, with fewer accelerations and decelerations, than in 30mph zones. This smoother driving style reduces particulate emissions from tyre and brake wear - which still represents a significant cause of air pollution from zero-emission vehicles."
"At 20 mph, as noted above, once the brakes are applied, it takes approximately 19 feet to stop. However, at 30 mph, the braking distance is not the expected 29 or 30 feet, but actually closer to 43 feet."
"The new speed limits will be introduced in stages over the next few months before the end of the year. Lowering speed limits is a key part of the Mayor's Vision Zero goal to eliminate death and serious injury from London's transport network and to enable more walking and cycling in the capital."
