THE DESIGN OF NON-SIGNALISED JUNCTIONS

This paper discusses the quantifiable factors of capacity, delay and safety, with the objective of highlighting recent research findings which can be widely applied. Concepts such as capacity, delay, and level of service are defined, and major/minor priority junctions are discussed. Gap acceptance and calculation of capacity and delay are outlined. Safety aspects are discussed and it is noted that junctions at which right-turning vehicles have to make a square or more acute angled turn from the major road, should be avoided, whereas for right-turning vehicles emerging from the minor road the square or more acute turn is preferable. The reconstruction of major/minor roads to provide necessary stagger is discussed as well as the traffic conflicts technique for studying junction safety. The principles of efficient and safe design of roundabout junctions of all types are described, and the way in which procedures for capacity and delay prediction will develop are indicated. Grade-separated and motorway junctions are discussed with special reference to parts of the interchange design task.
