Length of Transition Curve according to Rate of change of Centrifugal Acceleration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Transition Curve = Design Speed on Highways^3/(Rate of Change of Centrifugal Acceleration*Radius of Curve)
L_s = v₁^3/(C*R_t)
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.
Design Speed on Highways - (Measured in Meter per Second) - Design Speed on Highways is the maximum limit of speed of vehicle that can be arrived in highways.
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 of Curve - (Measured in Meter) - The Radius of Curve is defined as the horizontal curve with a specific radius which quantifies smoothness and ease of vehicle movement through a curve.

STEP 1: Convert Input(s) to Base Unit

Design Speed on Highways: 17 Meter per Second --> 17 Meter per Second No Conversion Required
Rate of Change of Centrifugal Acceleration: 0.45 Meter per Cubic Second --> 0.45 Meter per Cubic Second No Conversion Required

Length of Transition Curve according to Rate of change of Centrifugal Acceleration Formula

LaTeX Go

Length of Transition Curve = Design Speed on Highways^3/(Rate of Change of Centrifugal Acceleration*Radius of Curve)
L_s = v₁^3/(C*R_t)

Why is the rate of change of centrifugal acceleration introduced?

At the tangent point the centrifugal acceleration is zero and infinity at radius R. Hence the centrifugal acceleration is distributed over transition curve.

Explanation of introduction of centrifugal acceleration

The centrifugal acceleration should be developed at such a low rate that it will not cause discomfort for passengers of a vehicle travelling at a design speed.
