Road design refers to the planning and creation of roadways to ensure safe and efficient transportation. It involves considering factors such as traffic flow, vehicle types, and environmental impact. Engineers use various techniques to determine the best layout, materials, and features, such as curves, intersections, and drainage systems. Effective road design also prioritizes the needs of all users, including pedestrians, cyclists, and motorists. This includes implementing features like crosswalks, bike lanes, and proper signage. By focusing on safety and accessibility, road design aims to reduce accidents and improve overall travel experience.
