Roundabouts, which are circular intersections that allow vehicles to flow continuously, have been shown to be more efficient than traditional traffic lights. In Keene, the implementation of roundabouts has resulted in a decrease in idling and stop-and-go traffic, which are major contributors to air pollution and greenhouse gas emissions. The article suggests that the success of Keene's approach has drawn the attention of other municipalities seeking to address similar challenges.
