Studs light the way

摘要

The first of its kind in the UK, this installation uses the IRS2 intelligent hardwired road stud to increase driver awareness and improve lane discipline on and off the roundabout.Located to the south of Edinburgh, the Sheriffhall roundabout provides a critical link between the A7 trunk road and the Edinburgh City Bypass, the A720, one of the main feeder routes into Edinburgh. The roundabout itself has four lanes with six arms off the roundabout two of which, both A720 approaches, also have four lane entries.Improvements and efficiencies made to Sheriffhall roundabout in recent years have dramatically increased its capacity. Bear Scotland, who manage this section of the road network on behalf of Transport Scotland, were eager to ensure safety measures were improved in line with the increased use of the roundabout. Upon investigation it was found that inadvertent lane drifting was a significant contributory factor in challenges to negotiating it safely.
