Question 1.
What is a parabolic vertical curve?
Show hintHide hint
Think about the shape and purpose of such curves.
Question 2.
Calculate the minimum length for overtaking if a design requires a parabolic curve.
Show hintHide hint
Refer to the design standards for guidance.
3Question 3.
What is the minimum length required for overtaking on a parabolic vertical curve?
- 800 m
- 1080 m
- 1200 m
Show hintHide hint
Think about safe driving regulations.
4Question 4.
Is stopping visibility less critical than overtaking visibility?
- True
- False
Show hintHide hint
Consider how each factor impacts driving.
Question 5.
Design a parabolic vertical curve that connects a +2.5% and -3.0% gradient considering visibility for both overtaking and stopping. Calculate the necessary lengths and justify your choices based on UK standards.
Show hintHide hint
Use the same formulas and standards discussed in class.
Question 6.
Evaluate a scenario where the suggested stopping visibility isn't reflected in the design. What could be the repercussions if drivers can't see an upcoming obstruction?
Show hintHide hint
Consider both regulatory and practical implications.
