Engineers consider the following characteristics when determining the best solution for a particular intersection: Do you feel anxious at the thought of driving a roundabout? But in the United States, one- and two-lane roundabouts are far more common because as you increase the number of lanes going around a roundabout, it gets more complicated, especially at the exit lanes, explains Lalani.

Improper Roundabout Design Citing several studies involving U.S. traffic crashes, the IIHS site reports a 72 to 80 percent decline in vehicular crashes that cause injuries and a 35 to 47 percent reduction in all crashes after an intersection is converted to a modern roundabout. With respect to fixed objects within the central island, the context of the site matters, says Johnson. The Highway Loss Data Institute (HLDI) shares and supports this mission through scientific studies of insurance data representing the human and economic losses resulting from the ownership and operation of different types of vehicles and by publishing insurance loss results by vehicle make and model. An Indiana city has the most roundabouts in the country.
