The type of crossing and use of traffic lights depends on the type of roundabout and its location. The local highway authority is responsible for deciding the most appropriate type of crossing and junction control.
Department for Transport advice on pedestrian crossings is given in two Local Transport Notes, LTN 1/95 The Assessment of Pedestrian Crossings and LTN 2/95 The Design of Pedestrian Crossings. LTN 2/95 provides advice on pedestrian crossings on the approaches to roundabouts and at traffic light controlled junctions. This advice includes the need to consider linking crossings with other nearby traffic lights to co-ordinate when the lights change and ease traffic flow.
The Department has commissioned research to examine options for traffic lights at roundabouts. We will consider the need for further guidance when that research is complete.
