Roundabout intersections have been shown to

Position 1: These combined safety and environmental benefits have led many transport authorities to adopt roundabouts as a preferred design standard for new road projects.

Position 2: Their design forces drivers to slow down and yield to circulating traffic, thereby eliminating the high-speed right-angle collisions that frequently occur at signal-controlled crossings.

Position 3: Furthermore, because vehicles move continuously rather than stopping at red lights, roundabouts also decrease fuel consumption and carbon emissions.

Position 4: Roundabout intersections have been shown to significantly improve traffic safety compared with traditional signalised junctions.

Position 5: Studies conducted across multiple countries indicate that converting a standard intersection to a roundabout reduces fatal crashes by an average of 90 percent.
