This formula uses 4 Variables
Variables Used
Centrifugal Ratio - Centrifugal Ratio is defined as the ratio of centrifugal force to weight of vehicle.
Vehicle Velocity - (Measured in Kilometer per Hour) - Vehicle Velocity can be described as the amount of distance vehicle travelled in a perticular time.
Curve Radius - (Measured in Meter) - Curve Radius is the radius of a circle whose part, say, arc is taken for consideration.
Acceleration due to Gravity - (Measured in Meter per Square Second) - The Acceleration due to Gravity is acceleration gained by an object because of gravitational force.
STEP 1: Convert Input(s) to Base Unit
Vehicle Velocity: 80 Kilometer per Hour --> 80 Kilometer per Hour No Conversion Required
Curve Radius: 200 Meter --> 200 Meter No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
PWratio = V^2/(RCurve*g) --> 80^2/(200*9.8)
Evaluating ... ...
PWratio = 3.26530612244898

What is a Transition Curve?

For high-speed traffics over alignment on which the curves are circular arcs, an abrupt change from a straight path to a circular path is required at the point of curvature. It is obviously impossible to make this change instantaneously. A curve of varying radius and varying curvature, introduced between the tangent length and a circular curve or between two branches of a compound curve, or a reverse curve to provide such a transition is known as a transition or an easement curve.

What are the Advantages of Transition Curve?

1. It allows a gradual transition of curvature from the tangent to the circular curve or from the circular curve to the tangent.
2. The radius of curvature increases or decreases gradually.
3. It is provided for the gradual change in super elevation in a convenient manner.
4. It eliminates the danger of derailment, overturning or side slipping of vehicles, and discomfort to passengers.
