2.39. What are different types of vertical curves? What is the use of having a vertical curve as parabola and not a circle?

Try these first

1. 1.

   What are the two main types of vertical curves?

   Hint

   Think about the shapes and their characteristics.

2. 2.

   What is a primary benefit of parabolic curves?

   Hint

   Consider how drivers might feel in a vehicle.

3. 3.

   What type of curve is generally preferred for high-speed roads?

   • Circular
   • Parabolic
   • Linear

   Hint

   Think about the acceleration and comfort during high speeds.

4. 4.

   True or False: Circular curves are suitable for high-speed roads due to their simplicity.

   • True
   • False

   Hint

   Consider the impacts of sudden changes on high speeds.

5. 5.

   Design a roadway incorporating both parabolic and circular curves, providing the rationale for your selections based on traffic volume and speed.

   Hint

   Consider safety and comfort for various vehicle speeds.

6. 6.

   Considering environmental impacts, discuss how the choice of vertical curves can accommodate natural terrain without compromising safety and visibility.

   Hint

   Think about a road that must move with the ground's natural flow.
