FDOT has adopted the NCHRP Report 672, Roundabouts: An Informational Guide, (TRB, 2010) as the primary reference for roundabout design criteria, subject to requirements specific to Chapter 213 of the FDOT Design Manual. Links to these reference materials are provided below:
Current FDOT policy on roundabouts states the following:A roundabout alternative must be evaluated on new construction and reconstruction projects. Evaluation is also required for all other types of projects that propose new signalization or require a change in an un-signalized intersection control. An evaluation is not required for minor operational improvements such as changes to signal phasing, or for signal replacement projects where the primary purpose is to upgrade deficient equipment and installations.

While roundabouts may provide a community enhancement, they are not be constructed on state roads solely for this purpose.
This policy recognizes the many potential safety, operational, and capacity benefits afforded by roundabouts and strives to promote their use throughout the state when appropriate.
