of the Comprehensive Plan. He noted that Marion County is looking at the possibility of more roundabouts, with their residents. oMatt Reinhart discussed how Volusia County is advancing roundabouts and that their use of slip lane roundabouts seems to help people more easily understand how to use the roundabouts and be more comfortable with roundabouts. oChris Thibodeau discussed how there are numerous roundabouts, communities requesting roundabouts now that they are getting accustomed to them. Brett noted

on physics. Examples include roundabouts, splitter medians (horizontal deflection), and raised, Roundabouts Roundabouts are effective as a transition from a higher speed context to a lower speed context. On the State Highway System (SHS), modern roundabouts are standard, but smaller roundabouts (sometimes referred to as “mini-roundabouts”) may be appropriate in contexts where operating speeds of 25 mph or less are desired. See FDM 213 for roundabout design criteria. When used
