This is a callout box containing a diagrams, explanatory text, and a photo. The first diagram shows the conflict points for signalized intersections versus a roundabout. The signalized intersection has the four conflicts in each traffic direction:
The roundabout has two vehicle pedestrian conflicts at each road entering or leaving the roundabout, one for vehicles crossing into the roundabout and one for vehicles exiting the roundabout.
The text reads as follows: "Less conflict. Roundabouts have fewer conflict points. A single lane roundabout has 50% fewer pedestrian-vehicle conflict points than a comparable stop or signal controlled intersection. Conflicts between bicycles and vehicles are reduced as well."
The photo shows pedestrians and bicyclists safely crossing traffic into a pedestrian refuge at a roundabout.
