Modern Roundabouts: What? Why? How?

Not all circular intersections are roundabouts!  This presentation is designed to discuss:

  • what a modern roundabout is (and what it is not)
  • why modern roundabouts are being planned, designed and constructed at record rates across the U.S.
  • show how roundabouts can best be utilized to meet various transportations challenges more efficiently and effectively than other intersection controls
  • examine some specific design parameters like location, size, bicycle and pedestrian accommodation and more

The speaker will also walk you through some project examples to further illustrate these points.
