Challenge Problems
Push your limits with challenges.
Question 1
A road is designed with a stopping sight distance of 200m. Calculate the length of the summit curve ensuring the height of obstruction is 0.2m.
💡 Hint: Use the geometry rules related to parabolas.
Question 2
If the driver's eye height is increased to 1.5m, how would this affect the length of the summit curves for roads where gradients vary significantly?
💡 Hint: Consider how the parabolic equation shifts with changes in height.
