Deviation Angle Given Length of Valley Curve Less than Stopping Sight Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Deviation Angle = (2*Sight Distance)-(2*Driver Sight Height+(2*Sight Distance*tan(Inclination)))/(Length of Curve)
N = (2*S)-(2*h₁+(2*S*tan(α_angle)))/(L_s)
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

Deviation Angle - (Measured in Radian) - Deviation Angle is the angle between the reference direction and the observed direction.
Sight Distance - (Measured in Meter) - Sight Distance is s the minimum distance between two vehicles moving along a curve, when the driver of one vehicle can just see the other vehicle on the road.
Driver Sight Height - (Measured in Meter) - Driver Sight Height refers to the vertical distance between the driver's eye level and the road surface while seated in a vehicle.
Inclination - (Measured in Radian) - Inclination refers to the angle or slope of an object or surface concerning the horizontal plane.
Length of Curve - (Measured in Meter) - Length of Curve is the distance along the road where the alignment changes from upward to downward slope, creating a valley-shaped concave.

STEP 1: Convert Input(s) to Base Unit

Sight Distance: 3.56 Meter --> 3.56 Meter No Conversion Required
Driver Sight Height: 0.75 Meter --> 0.75 Meter No Conversion Required
Inclination: 2 Degree --> 0.03490658503988 Radian (Check conversion here)
Length of Curve: 7 Meter --> 7 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N = (2*S)-(2*h₁+(2*S*tan(α_angle)))/(L_s) --> (2*3.56)-(2*0.75+(2*3.56*tan(0.03490658503988)))/(7)

Evaluating ... ...

N = 6.87019487445983

STEP 3: Convert Result to Output's Unit

6.87019487445983 Radian --> No Conversion Required

FINAL ANSWER

6.87019487445983 ≈ 6.870195 Radian <-- Deviation Angle
