STEP 0: Pre-Calculation Summary
Formula Used
Length of Valley Curve = (Deviation Angle*Stopping Sight Distance^2)/(2*Average Head Light Height+2*Stopping Sight Distance*tan(Beam Angle))
LVc = (N*SSD^2)/(2*h1+2*SSD*tan(α))
This formula uses 1 Functions, 5 Variables
Functions Used
tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
Variables Used
Length of Valley Curve - (Measured in Meter) - Length of valley curve is the valley transition curve made fully transitional by providing two similar transition curves of equal length.
Deviation Angle - Deviation Angle of Vertical curve is the algebraic difference in grades or gradiests.
Stopping Sight Distance - (Measured in Meter) - Stopping Sight Distance is defined as distance provided on the road before a sharp turn.
Average Head Light Height - (Measured in Meter) - Average Head Light Height is the minimum height of the head light provided.
Beam Angle - (Measured in Radian) - Beam angle is the angle between the two directions for which the intensity is 50% of the maximum intensity as measured in a plane through the nominal beam centerline.
STEP 1: Convert Input(s) to Base Unit
Deviation Angle: 0.08 --> No Conversion Required
Stopping Sight Distance: 160 Meter --> 160 Meter No Conversion Required
Average Head Light Height: 0.75 Meter --> 0.75 Meter No Conversion Required
Beam Angle: 2.1 Degree --> 0.036651914291874 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
LVc = (N*SSD^2)/(2*h1+2*SSD*tan(α)) --> (0.08*160^2)/(2*0.75+2*160*tan(0.036651914291874))
Evaluating ... ...
LVc = 154.754460642456
STEP 3: Convert Result to Output's Unit
154.754460642456 Meter --> No Conversion Required
FINAL ANSWER
154.754460642456 154.7545 Meter <-- Length of Valley Curve
(Calculation completed in 00.020 seconds)
