Length of Transition Curve by Empirical Formula for Plain and Rrolling Terrain Solution

STEP 0: Pre-Calculation Summary

Formula Used

Transition Curve Length for Terrain = (2.7*(Design Speed on Highways)^2)/Radius of Curve for Road
L_Terrain = (2.7*(v₁)^2)/R_t
This formula uses 3 Variables

Variables Used

Transition Curve Length for Terrain - (Measured in Meter) - Transition Curve Length for Terrain should be such that full super elevation is attained at the end of the transition curve and applied at a suitable rate.
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.
Radius of Curve for Road - (Measured in Meter) - Radius of Curve for Road can be defined as the radius at which the spiral is joined.

STEP 1: Convert Input(s) to Base Unit

Design Speed on Highways: 17 Meter per Second --> 17 Meter per Second No Conversion Required
Radius of Curve for Road: 300 Meter --> 300 Meter No Conversion Required
