Challenge Problems
Push your limits with advanced challenges
Design a reverse curve for a highway segment connecting two lines. The first has a radius of 900m, and the second radius should allow for a smooth transition given a deflection angle of 45°. Calculate the required parameters.
💡 Hint: Apply trigonometric functions and verify your design against safety standards.
A reverse curve connects two roads with an initial radius of 500m and an ending radius of 300m. How would you calculate the external distance and length of the curve?
