2.7. Vertical Curves

Try these first

1. 1.

   What is a summit curve?

   Hint

   Focus on how the slopes meet.

2. 2.

   What is the primary purpose of vertical curves?

   Hint

   Think about road safety.

3. 3.

   What type of curve is usually used for upward transitions?

   • Summit
   • Valley
   • Straight

   Hint

   Think about what happens when two slopes meet.

4. 4.

   True or False: Valley curves are more straightforward to design than summit curves.

   • True
   • False

   Hint

   Consider the safety aspects.

5. 5.

   Design a vertical curve connecting a 2% upgrade to a 0% downgrade with an ideal sight distance of 200 meters. Calculate the required length of the curve.

   Hint

   Apply the formula based on the gradients given.

6. 6.

   Evaluate the effect of a sharp valley curve on vehicle dynamics, especially during nighttime.

   Hint

   Consider real-world scenarios to explain.
