20- 25% of all road accidents in rural areas occur at junctions. The corresponding figure for urban areas is 50- 60%. The purpose of this memorandum is to survey current knowledge of the influence of different design and control on traffic safety. Most attention has been devoted to at- grade junctions. Rural junctions have received more interest than urban junctions. The survey deals only to a limited extent with the road safety situation for pedestrians and cyclists.
