The Ins and Outs of Roundabouts

 

ERRATUM

 

There is a small error on page 9. In the legend of the graph on page 9, the colors for "Uncontrolled" and "Roundabouts" have become transposed. The "Uncontrolled" should be the purple color and the "Roundabout" should be the blue color. Please can you amend the legend to correct this error?

 

Thank you.
