Challenge Problems
Push your limits with advanced challenges
A highway curves with a radius of 400 m. Calculate the required transition length for a vehicle traveling at 90 km/h. Discuss how terrain impacts the formula you’d use.
💡 Hint: Make sure to convert speed to appropriate units for calculation.
Analyze a road design where superelevation starts at zero and needs to reach 0.08 over a length defined by 1 in 100. How would you determine the transition length?
💡 Hint: Pay attention to the equation structure for calculating superelevation changes.
