Driver Sight Height given Angle Grades Solution

STEP 0: Pre-Calculation Summary

Formula Used

Driver Sight Height = (Sight Distance-Length of Curve/2-The Height of The Obstruction/Negative Grade Angle)*Positive Grade Angle
h₁ = (S-L_s/2-h₂/n₂)*n₁
This formula uses 6 Variables

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.
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.
The Height of The Obstruction - (Measured in Meter) - The Height of The Obstruction refers to its vertical dimension, blocking a line of sight or path, often in transportation, construction or safety.
Negative Grade Angle - A negative grade angle indicates an incline slope.
Positive Grade Angle - (Measured in Radian) - A positive grade angle indicates an upward slope.

STEP 1: Convert Input(s) to Base Unit

Sight Distance: 4.536929 Meter --> 4.536929 Meter No Conversion Required
Length of Curve: 8.953859 Meter --> 8.953859 Meter No Conversion Required
The Height of The Obstruction: 0.36 Meter --> 0.36 Meter No Conversion Required
Negative Grade Angle: -0.402266 --> No Conversion Required
Positive Grade Angle: 45 Degree --> 0.785398163397301 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h₁ = (S-L_s/2-h₂/n₂)*n₁ --> (4.536929-8.953859/2-0.36/(-0.402266))*0.785398163397301

Evaluating ... ...

h₁ = 0.750000048498681

STEP 3: Convert Result to Output's Unit

0.750000048498681 Meter --> No Conversion Required

FINAL ANSWER

0.750000048498681 ≈ 0.75 Meter <-- Driver Sight Height
