Length of Transition for Curve Plain and Rolling Terrain Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Transition Curve = (35*Velocity^2)/Radius for Transition Curve
L_c = (35*v_vehicle^2)/R_trans
This formula uses 3 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.
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
Radius for Transition Curve: 300 Meter --> 300 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_c = (35*v_vehicle^2)/R_trans --> (35*28.23^2)/300

Evaluating ... ...

L_c = 92.975505

STEP 3: Convert Result to Output's Unit

92.975505 Meter --> No Conversion Required

FINAL ANSWER

92.975505 ≈ 92.9755 Meter <-- Length of Transition Curve

< Design of Transition Curves and Setback Distances Calculators

Length of Transition Curve given Super-Elevation

Go Length of Transition Curve = Allowable Rate of Super Elevation*Rate of Super Elevation*(Total Widening Needed at Horizontal Curve+Normal Width of Pavement)

Length of Transition Curve given Centrifugal Acceleration

Go Length of Transition Curve = Velocity^3/(Rate of Change of Centrifugal Acceleration*Radius for Transition Curve)

Rate of Change of Centrifugal Acceleration

Go Rate of Change of Centrifugal Acceleration = Velocity^3/(Length of Transition Curve*Radius for Transition Curve)

Rate of Change of Centrifugal Acceleration given Empirical Formula

Go Rate of Change of Centrifugal Acceleration = 80/(75+3.6*Velocity)
