Inattentional Blindness and road safety: the potential role of intelligent road studs in reducing accidents

Llewellyn, Richard; Ladyman, Stephen

Abstract

In-vehicle distraction is often the subject of debate in relation to road safety. Distractions outside of the vehicle, however, are often overlooked. Both situations result in cognitive capture, a form of 'Inattentional Blindness'. This paper investigates the lesser understood external distractions to drivers, and how intelligent transport systems such as illuminated road studs can improve road safety. A case study of a busy roundabout on the Edinburgh City Bypass is described. Using before and after videos surveys, it is demonstrated that the installation of intelligent road studs significantly reduces the number of lane transgressions at the roundabout. Results were found to be valid across all vehicle types, in both daylight hours and at night. The study suggests that the studs have a positive impact on driver behaviour and reduce the incidence of inattentional blindness, thereby improving road safety at such junctions.
