The aim of this research is to identify and quantify the changes to driver behaviour, with a specific emphasis on safety, that result from the installation of illuminated road studs when compared with conventional road marking technologies. This includes defining what safe driver behaviour means, how it is exhibited by drivers and assessing the impact of the installation of illuminated road studs in various different road scenarios.

Field trials of the road stud are being progressed in various locations on the Scottish trunk road network. Scenarios being tested include the use of studs at roundabouts, priority junctions and on highway link sections. Research is being undertaken using a combination of naturalistic study and driver behaviour questionnaires. The project is being progressed with partners in industry and the national trunk road authority, Transport Scotland.
