Roundabouts have started appearing at intersections that once relied on stop signs and traffic lights, changing how drivers move through cities in a noticeable way. These circular intersections are not random design experiments; they reflect a major shift in how planners think about traffic flow, safety, and long-term infrastructure costs. Drivers now encounter roundabouts in residential neighborhoods, busy commercial corridors, and even near highways where congestion used to build quickly.
The rise of roundabouts also connects to a broader effort to modernize road systems without constantly expanding them. Instead of widening intersections or adding more traffic lights, planners increasingly rely on roundabouts to manage vehicle movement more efficiently. This shift affects everyday driving habits, insurance risks, and even fuel consumption patterns across cities.
