Directly proportional to the velocity and also inversely proportional to the radius of curvature.

e+f = (0.278V)'2/9.8R.
So, option A is correct.
So, option A is correct.

Super elevation is inversely proportional to the radius.
E!=e B where e is the super-elevation.
E!=e B where e is the super-elevation.

Super elevation doesn't depends on road width, The E value (height of outer edge of road at super-elevation) depends upon e (rate of super-elevation).

Guys. Question is actually trick you. B is Right.
E=eB.
e=v*v/gR.
SO,
E=v*v*B/gR.
From the final equation.
E directly proportion to width, the square of the velocity and, inversely proportional to the g and R.
here, superelevation does not directly proportional to the velocity of vehicles, but the only square of the velocity.
SO, answer B IS RIGHT.

e=v^2/Rg so directly proportional to the square of thè velocity.

How?

It is directly proportionel to quare of velocity not directly proportionl to single velocity.

For the total amount of superelevation, A, C, and D are correct.
So, incorrect can only be B as it is proportional to the square of the speed and not the speed only.
So, incorrect can only be B as it is proportional to the square of the speed and not the speed only.
