Question 1.
What is super-elevation?
Show hintHide hint
Think of how banks are built at curves.
Question 2.
Define a transition curve.
Show hintHide hint
Consider what happens when a straight road suddenly turns.
3Question 3.
What is the formula for calculating super-elevation?
- h = (bv^2) / (gR)
- h = (gbR^2) / v^2
- h = (vg) / (bR)
Show hintHide hint
Look for the formula that includes v, g, and R effectively.
4Question 4.
True or False: Transition curves can negatively impact vehicle stability if designed inadequately.
- True
- False
Show hintHide hint
Think about what happens when vehicles approach a sudden curve.
Question 5.
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.
Show hintHide hint
Refer to design guidelines for safe transitions and adjust measurement accordingly.
Question 6.
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.
Show hintHide hint
Review how changing gradients affect visibility and comfort.
