In 2014, following a Stage 4 Road Safety Audit which cited poor lane discipline as the prime cause of collisions at the roundabout, BEAR (Scotland), the contracted Operating Company for Transport Scotland at the time, proposed a new, more radical approach to improve the safety record of the roundabout. The Audit had suggested that lane transgression was likely to be due to the level of difficulty that certain drivers may experience in understanding and reacting to the complexity of the junction. Therefore, an LED-powered, intelligent road stud scheme was proposed. The intention being that the studs would encourage drivers to stay within their lane by drawing drivers’ attention to the delineation of the existing lane markings and guide them through the roundabout.

The selection of Clearview’s Intelligent Road Stud (IRS2) low profile stud was a major factor in the choice of technology as it minimises the hazard to powered two-wheelers and cyclists.
Independent evaluation by researchers from the Transport Research Institute at Edinburgh Napier University conducted a full ‘before and after’ study on driver behaviour at the roundabout with over 55,000 individual vehicle movements being analysed.

On behalf of Police Scotland’s Trunk Road Traffic Management team and our road patrol officers, the Intelligent Road Studs have clearly improved the lane discipline and driver behaviour of local and strategic users of Sheriffhall Roundabout. We would certainly advocate their implementation elsewhere.
