What is Vertical Curve Design in Highways about?

Vertical curves provide a gradual slope transition between two sections of roadway with different grades. There are two types: crest curves for downhill transitions and sag curves for uphill. The design is based on factors like speed, drainage, and sight distance to ensure safety and comfort. Sag curves are used for positive grade changes like valleys, while crest curves are used for negative grade changes.
