What is road banking?
Banking of Roads . The phenomenon of raising outer edge of the curved road above the inner edge is to provide necessary centripetal force to the vehicles to take a safer turn and the curved road is called Banking of Roads....
explanation:
Fig. (1) Vehicle moving on level road
In fig (1), it is shown that a vehicle of weight ‘mg’ (acts vertically downwards) is moving on a level curved road. R1 and R2 are the forces of normal reaction of the road on the wheels. These are vertically upward since road is leveled. Hence,
R1 + R2 = mg
Let F1 & F2 are forces of frictions between tyre and road directed towards centre of curved road.
∴ F1 = μ R1
And
F2 = μ R2
where μ is coefficient of friction between tyres and road.
If ‘v’ is the velocity of the vehicle while rounding the curve, the centripetal force required is mv²/r. As this force is provided by the force of friction therefore

Hence the maximum velocity with which a vehicle can go round a level curve; without skidding is
Answer:
Banking of roads is defined as the phenomenon in which the edges are raised for the curved roads above the inner edge to provide the necessary centripetal force to the vehicles so that they take a safe turn. ... The angle at which the vehicle is inclined is defined as the bank angle.
