This Note is to provide assistance to those in involved in the design and operation of signalised roundabouts. This includes roundabouts to which signals have been added as well as junctions designed as signalised roundabouts from the outset. The concept of a roundabout covers a wide range of junctions varying in size, complexity and traffic loading. When traffic signals are added , the number of design considerations increases and no two signalised roundabouts will be the identical. This Note will assist the designer by identifying the issues that need to be addressed and providing guidance on how they can be dealt with.
