Why a roundabout?
MDT considered several options for improving the Lincoln Road and Applegate Drive intersection including traffic signals and a four-way stop. The improvement options were evaluated on the basis of how well they reduce the number and severity of crashes, and improve traffic operations. Based on statewide safety data, a traffic analysis, and input from the community, MDT determined that the intersection would benefit most from a roundabout design.
Roundabouts have been shown to achieve up to a 90% reduction in fatal collisions over stoplights or stop signs. Roundabouts also have a number of benefits including:
- Improved efficiency and smoother traffic flow.
- Increased safety due to a reduction of conflict points and a reduced speed throughout the intersection.
- Up to an 89% reduction in delays and a 56% reduction in stops.
- A 40% reduction in pedestrian collisions.
