Roundabout Intersection Design and Traffic Flow Diagram #146108 (License: Personal Use)

This diagram depicts a typical single-lane roundabout at a four-way intersection, with asphalt roads, central island, and marked pedestrian crosswalks. Green directional arrows indicate clockwise vehicle movement, while white dashed lines denote lane boundaries and yield zones before entry. The design emphasizes safety, efficiency, and reduced conflict points compared to traditional intersections.

Used in transportation engineering resources, driver education materials, municipal planning websites, and traffic safety campaigns to explain roundabout operation and benefits to drivers, planners, and the public.
