An intersection is a location where two or more roads meet or cross each other, requiring traffic control measures to manage vehicle and pedestrian movements safely. Intersections range from simple two-road crossings to complex multi-road junctions with traffic signals, turn lanes, and pedestrian crosswalks. Municipal transportation departments design intersections based on traffic volumes, safety data, and surrounding land uses. Modern intersection design considers all road users including cyclists and people with disabilities. Roundabouts, traffic circles, and signalized intersections each have advantages depending on traffic patterns and available space.
