Roundabouts can, under certain conditions, offer significant advantages regarding some health determinants (Bellefleur & Gagnon, 2011). Existing evaluations indicate that they produce effects that are of interest to those concerned with road injuries, active transport, ambient noise levels, air quality and energy-related issues, in particular.
This briefing note provides a frame of reference for public health actors by:
(1) Summarizing some of the significant characteristics of this intervention (history, design, reasons for and conditions of implementation);
(2) Briefly summarizing the evaluative literature concerning the effects of roundabouts on a few public health determinants;
(3) Identifying some potential courses of action for their promotion, along with some related considerations.
