Challenge Problems
Push your limits with advanced challenges
A curve has a radius of 200 m. With a design speed of 60 km/h and a friction factor of 0.15, calculate the required superelevation using the IRC guidelines.
💡 Hint: Begin by converting speed to m/s and apply the formula for e.
Evaluate the impact of increasing truck traffic on existing urban road curves if currently designed for lower speeds, and suggest design changes.
💡 Hint: Consider how heavier vehicles affect road design.
