Road design is the process of planning and creating roadways to ensure safe and efficient travel for vehicles and pedestrians. It involves considering factors such as traffic flow, road materials, and environmental impact. Engineers use various guidelines and standards to determine the best layout, including the width of lanes, placement of signs, and the design of intersections. Effective road design also takes into account the needs of different users, including cars, bicycles, and public transport. By incorporating features like bike lanes, crosswalks, and traffic signals, designers aim to enhance safety and accessibility. Good road design contributes to smoother traffic movement and reduces the risk of accidents.
