Perhaps you have noticed that when a road is straight, it is horizontal too. However, when a sharp turn comes, the surface of the road does not remain horizontal. This is called banking of the roads . The angle through which the road is banked is called angle of banking.
For frictionless road:
tan θ = v^2/rg
=> θ = tan^-1(v^2/rg)
For road with friction:
tan θ = (v2 - μrg)/(rg + μv2)
=> θ = tan^-1[(v2 - μrg)/(rg + μv2)]
