Committee Scope

The Committee is concerned with all factors encompassing the planning, design and safe operation of modern roundabouts. Focus is on current issues, research dissemination and future research needs. We serve as a forum for discussions about roundabout research, projects, policy, and practices for all interested stakeholders. We identify research needs and prepare problem statements. We facilitate the exchange of research knowledge by various media, meetings, webinars and conferences.
