Total super elevation E= e * W.

Superelevation is directly proportional to velocity of the vehicle because for particular curve on the road radius of curve remains constant for that curve.

Super-elevation = v^2/2r.
Hence, it should be directly proportional to square root of velocity and inversely proportional to the radius of curvature.
Hence, it should be directly proportional to square root of velocity and inversely proportional to the radius of curvature.

e is the rate of superelevation.
h = e * B is the super elevation (which is proportional to width).
h = e * B is the super elevation (which is proportional to width).

e is directly proportional to v^2 and also inversely proportional to R.

No @Mr. Prasanna,
Total super elevation = e*W.
Where e - rate of SE.
W - Width of pavement.
Total super elevation = e*W.
Where e - rate of SE.
W - Width of pavement.

e = WV^2/gR.
V^2 is direct proportional.
V^2 is direct proportional.

I think answer should be option (a), because question asking for incorrect statement.

Super elevation is directly proportional to the square of the velocity and inversely proportional to the acceleration due to gravity, radius of the curvature.

e+f=(v*v)/gR
So directly prop to v.
Indirectly prop to radius and gravity.
Hence option A would be the answer.
