Challenge Problems
Push your limits with advanced challenges
Given a roadway that needs to connect two straight paths with a deflection angle of 30° and a point 150m from the start, derive the necessary tangent length and total curve length assuming a radius of 600m.
💡 Hint: Ensure to convert degrees into radians before calculating.
You have an existing curve that needs adjustment. If the deflection angle is decreased to 18° while keeping the radius constant, how will that affect the tangent lengths and overall curve length?
💡 Hint: Predict how curvature changes influence roadway alignment.
