Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Use the same formulas and standards discussed in class.
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?
💡 Hint: Consider both regulatory and practical implications.
