Driver Sight Height given Length of Valley Curve Less than Stopping Sight Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

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.
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.
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.
Inclination - (Measured in Radian) - Inclination refers to the angle or slope of an object or surface concerning the horizontal plane.

STEP 1: Convert Input(s) to Base Unit

Deviation Angle: 236.5494 Degree --> 4.1285658736163 Radian (Check conversion here)
Sight Distance: 3.56 Meter --> 3.56 Meter No Conversion Required
Length of Curve: 7 Meter --> 7 Meter No Conversion Required
Inclination: 2 Degree --> 0.03490658503988 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h₁ = (N*(2*S-L_s)-(2*S*tan(α_angle)))/2 --> (4.1285658736163*(2*3.56-7)-(2*3.56*tan(0.03490658503988)))/2

Evaluating ... ...

h₁ = 0.12339601302638

STEP 3: Convert Result to Output's Unit

0.12339601302638 Meter --> No Conversion Required

FINAL ANSWER

0.12339601302638 ≈ 0.123396 Meter <-- Driver Sight Height
