Mini-roundabouts have the same operational characteristics of regular size roundabouts. However, their defining feature is a traversable central island that helps improve vehicle, bicycle, and pedestrian safety, and reduce noise and emission levels. If properly designed, they can facilitate surface water drainage, accommodate snow plows, and improve visibility at night.
Learning Objectives:
1. Examine the benefits of mini-roundabout implementation.
2. Identify design opportunities to implement a mini-roundabout.
3. Estimate changes in intersection traffic flow with mini-roundabout implementation.
