Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for calculating super-elevation?
- h = (bv^2) / (gR)
- h = (gbR^2) / v^2
- h = (vg) / (bR)
💡 Hint: Look for the formula that includes v, g, and R effectively.
Question 2
True or False: Transition curves can negatively impact vehicle stability if designed inadequately.
- True
- False
💡 Hint: Think about what happens when vehicles approach a sudden curve.

Question 1
Design a roadway with a transition curve for a vehicle speed of 60 m/s and a curve radius of 150 m. Determine the length needed for a smooth transition.
💡 Hint: Refer to design guidelines for safe transitions and adjust measurement accordingly.
Question 2
A vertical curve is designed to connect two road segments with gradients of +2% and -2%. Determine the ideal length of the vertical curve for smooth transition.
💡 Hint: Review how changing gradients affect visibility and comfort.
