Length of Transition Curve given Centrifugal Acceleration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Transition Curve = Velocity^3/(Rate of Change of Centrifugal Acceleration*Radius for Transition Curve)
L_c = v_vehicle^3/(C*R_trans)
This formula uses 4 Variables

Variables Used

Length of Transition Curve - (Measured in Meter) - Length of Transition Curve is a curve in plan which is provided to change the horizontal alignment from straight to circular curve.
Velocity - (Measured in Meter per Second) - Velocity is the rate of change of distance of the vehicle with respect to time.
Rate of Change of Centrifugal Acceleration - (Measured in Meter per Cubic Second) - Rate of Change of Centrifugal Acceleration should be such that it will not cause discomfort to passengers.
Radius for Transition Curve - (Measured in Meter) - Radius for Transition Curve is the radius at the point of transition curve of roadways.

STEP 1: Convert Input(s) to Base Unit

Velocity: 28.23 Meter per Second --> 28.23 Meter per Second No Conversion Required
