This study of dual-carriageway trunk roads of modern design quantifies the relationships between the numbers of injury accidents that occur, and the traffic and road layout variables that determine them. The study covers 112 new schemes, opened since 1968, on non-built-up-dual-carriageway trunk roads in England. The study used the technique of generalised linear modelling to develop predictive relationships between numbers of accidents, traffic flow and geometric features of the road. The main results of this study refer to road links, that is, the stretches of road between junctions. (A)
