Geometric Design is about planning and designing the physical features of roads, highways, and intersections to make them safe and efficient. It involves determining things like how wide roads should be, how sharp curves can be, how steep hills can be, and how intersections should be laid out. Think of it as creating a blueprint for roads that ensures cars, trucks, and pedestrians can move safely. This is a key skill in traffic engineering and civil engineering, similar to how an architect designs buildings, but for transportation systems instead. You might also see this referred to as "Highway Design" or "Roadway Design."
