Five years on: Active road studs at the Sheriffhall roundabout
Article in Highways reflects on research which Richard Llewellyn was involved in and the impact it has had 5 years on.
“Following the installation of active road studs at Sheriffhall Roundabout this research has found an improvement in lane discipline, a reduction in vehicle conflicts and a reduction in injury collisions exceeding the national average over the same period.”
Great work Richard and it’s great to see lasting casualty reduction being achieved.
