When vehicle go through turnings, they travel along a nearly
circular arc. There must be some force to produce the required centripetal
acceleration. Centripetal force is provided to the vehicle by following three
ways1.By friction only2.By banking of roads only3.By friction and banking of
roads both.
By banking of roads only:
To avoid friction outer part of road is some what lifted compared to the inner
part.
NSin
= 
and NCos = mg
From this we get, Tan = 
At two speeds car does not slide down even if track is smooth.
