ROAD EDGELINING AND ACCIDENTS: AN EXPERIMENT IN SOUTH-WEST ENGLAND

A before-and-after study of the effects of road edgelining on accident frequency was carried out using 600 kilometres of unlit rural roads in south-west England. Two alternative patterns of edgemarking were used, and the accident reduction at marked sites compared with that at unmarked control sites. The design and results of the study are described, and previous British studies of edgelining are also summarised. It is concluded that results to date are inconclusive as to whether edgemarking is a reliable accident prevention measure. (Author/TRRL)
