The design element provided to ensure safety of a vehicle travelling at a prescribed design speed along the curved segment of a highway is
-
- shoulder
- super-elevation
- median
- footpath
Correct Option: B
Super elevation is the amount by which the outer edge of a curve on a road or railway is banked above the inner edge. It helps to offset centripetal forces developed as the vehicle goes around a given curve. Along with the friction, on the road, super-elevation keeps vehicle from going off the road.
