Focus on how speed relates to required super-elevation.
A national highway has a curve with a radius of 300 m and a design speed of 75 km/h. Calculate the maximum allowable super-elevation and confirm its adequacy.
Always remember to compare your calculated value to 0.07.
Given a curve on a local road with a radius of 200 m and mixed traffic conditions, derive a super-elevation approach suitable for safety.
