What Are Vertical Curves?

Types of Vertical Curves

• Summit Curve.
• Valley Curve.

1. Summit Curve

2. Valley Curve

Application of Curves

1. Application of Horizontal Curve: The most important element of road geometry is a horizontal curve; the main function of a horizontal curve is to provide the smooth transition curve; that’s why it is widely used in highway curves. So, it is the application of horizontal curve.
2. Application of Vertical Curve: It is also a very important curve in road geometry. The vertical curve is mainly used where the gradient of the road is changed, so it is widely used in a mountain region. Another application of the vertical curve is the Hairpin bend the curve.

What Are Horizontal Curves?

Types of Horizontal Curves

1. Simple Curve: A simple arc provided in the road to impose a curve between the two straight lines.
2. Compound Curve: Combination of two simple curves combined together to curve in the same direction.
3. Reverse Curve: Combination of two simple curves combined together to curve in the same direction.
4. Transition or Spiral Curve: A curve that has a varying radius. Its provided with a simple curve and between the simple curves in a compound curve.
