Dear Editor,
It is good to know that 20mph speed limits make roads safer, even though they don’t have any more police enforcement than on 30mph roads.
New research from Transport for London has looked at the lives saved over a long-term period from 1989 to 2013. The direct effect of 20mph zones has led to a 40% reduction in the number of people killed. The improvements have been even better for children.
The analysis shows there are over 1,000 adults and children who would have been killed or injured in London if it were not for these road safety measures.
Many areas of Sheffield now have 20mph zones, after Green Party councillors successfully persuaded the council to start them in 2008. This is all part of making Sheffield a safe, pedestrian-friendly city.
