Challenge Problems
Push your limits with advanced challenges
You are tasked with designing a composite curve that connects two straights at a deflection angle of 15°30'. The central circular arc must have a radius of 600 m. Determine the lengths of the transition curves needed for comfort and safety.
💡 Hint: Refer to curve design standards for typical transition lengths.
A circular curve of radius 500 m needs to be replaced by two transition curves of equal lengths at each end. How do you determine the required new radius to ensure safe navigation?
💡 Hint: Use transition curve design equations to establish safe parameters.
