Derriford
Posted by Clive Sawers

This mini-roundabout serves Plymouth's Derriford Hospital; it can become quite busy at any time. The dominant movements are clear from the satellite view as are the predominant wheel tracks.
The downhill approach from the west uses a substantial build-out to control speed and anti-skid surfacing but is necessarily reduced to a single lane. Because the right turn out from the south is very low in volume the approach downhill does not queue much. The build-out creates a severe pinch-point for cyclists and on this occasion they are routed via a bypass.
