THE DISPLACED RIGHT TURN JUNCTION - PUTTING THEORY INTO PRACTICE

The concept of the Displaced Right Turn (DRT) is not new and has been considered as an alternative junction design to traditional at-grade and grade separated junctions since the 1950s. It enables one or more conflicting movements to take place away from the main intersection at a new 'crossover junction', reducing the number of conflicts at the central node. Tests have shown junction capacity can increase with a footprint similar to a large roundabout with only a small increase in costs The DRT concept is an innovative traffic signal junction being developed for the UK highway network by the Highways Agency. This paper summarises the research, undertaken on behalf of the Highways Agency. (A)
