Studies find that roundabouts reduce vehicle accidents by 40 percent at intersections and reduce vehicle accidents that cause injuries by 75 percent. Some towns and cities swear by these intersections; Keene, New Hampshire, installed its seventh roundabout in 2023. Besides saving $200,000 per stoplight they don’t have to install, a 2018 study found that the initial bout of roundabouts led to a decline of 40 percent in airborne particulates. By 2031, the city of Keene plans to install four more. In Carmel, Indiana, an engineer estimated that the city’s 150 roundabouts prevented the burning of 20,000 gallons of fuel annually.
