Geometric design of roads

Geometric design of roads is the way that roads are designed so they are safe, easy to drive on, and look nice. Roads need to be designed in a certain way so that cars and other vehicles can drive on them safely. To do this, roads have certain features like curves and slopes that help guide people as they are driving. Additionally, roads have certain signs and markings painted on them like white lines and stop signs to ensure people stay safe and obey the rules of the road. Finally, roads are designed to look nice, so engineers make sure to add features like streetlights, trees, and other decorations. All of these design elements combine to form a geometric design, which makes the roads look nice, keeps people safe, and makes sure people can drive comfortably.
