Speed , Distance & Time
Both the factors are directly related. Greater the speed (velocity), greater has to be the bending angle. Bike racing is the best example of this phenomena. Now similarly, this same concept applies to large vehicles like cars, bus , trucks , trains etc. But the problem here is these vehicles can't bend inward while taking curve turn. Only option left is slowing down of vehicle to minimum for smooth turning of vehicle. But this option is limited to small roads and with small vehicles. Slowing down of vehicles in every curve turn is not an appropriate solution for trains and vehilces in express highways. As you know that vehicles move is great speed in highways, i.e around 80-100 km/h.
The Banking of roads is only option left for smooth turning of vehicle without slowing down of the vehicle. Again we take the example of bike racing, they don't slow down their bike. Instead they bend inward in the direction of turning. This same technique is qpplied for large vehicle by lifting the outer part of roads or rails. As we know large vehicles can't bend like bikes and cycles to take turn. So , the Banking of Road is done for the smooth turning of vehicles.

Why do we need Banking of Roads ?
You must have heard the wordBanking, which is closely associated with finance and dealing with money. In this article we are not going to discuss about that banking. Banking of Roads or rails means tilting of roads from the outer side. You can see this Banking on highways or Railway tracts. The outer part of the road is tilted upward, which provides smooth turning of vehicle without skidding of vehicle out of road. Let's understand why do we need Banking of roads and rail tracks. When a cyclist or motor cyclist rides a two wheeler on the road. While taking a turn the cyclist bend towards inward or else he slow downs the vehicle. From here we come to the conclusion that inorder to take a curved turn, either speed of the vehicle has to be minimum or else increase the inward bending angle.

The Factors on which Banking of Roads depends :
- (i) Velocity (v):
- Speed of the Vehicle, while taking the curve turn.
- (ii) angle (tanΘ):
- angle at which the vehicle bends while taking turn.
- (iii) Radius of Curvature (r):
- The Radius of Curvature formed by arch along the path of moving vehicle.
