The potential impact of a 20mph speed limit on urban roads in Scotland

This paper was developed to provide evidence in relation to the forthcoming Scottish Parliament Member’s Bill proposing the introduction of a 20mph limit in urban settings across Scotland. In the paper, estimates are made of the likely reductions in casualties associated with the introduction of a 20mph speed limit on urban roads, based on evidence of speed reductions from existing schemes.

Reducing road speed is likely to save lives and reduce road injuries, particularly among more vulnerable road users like pedestrians and cyclists. A lower speed road environment will help encourage more people to walk and cycle in our towns and cities.
