In the last 20 years roundabouts have been successfully added to hundreds of intersections in North Carolina to improve safety and mobility. However, one challenge has been the construction cost. “Modular” roundabouts offer a novel way to implement these intersection improvements with significantly lower costs and impacts; the first one has now been installed in the western part of our state.
RTA Leadership Team member Bolton & Menk created a research report for RTA in fall 2022 that summarizes the benefits and opportunities of modular roundabouts. You can also download a presentation delivered in November 2022 at the NC Section ITE annual meeting.
