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

STEP 0: Pre-Calculation Summary
Formula Used
Driver Sight Height = ((Length of Curve-2*Sight Distance)*Deviation Angle+2*Sight Distance*tan(Inclination))/2
h1 = ((Ls-2*S)*N+2*S*tan(αangle))/2
This formula uses 1 Functions, 5 Variables
Functions Used
tan - Trigonometric tangent function, 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.
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.
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.
Deviation Angle - (Measured in Radian) - Deviation Angle is the angle between the reference direction and the observed direction.
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
Length of Curve: 7 Meter --> 7 Meter No Conversion Required
Sight Distance: 3.56 Meter --> 3.56 Meter No Conversion Required
Inclination: 2 Degree --> 0.03490658503988 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
h1 = ((Ls-2*S)*N+2*S*tan(αangle))/2 --> ((7-2*3.56)*0.88+2*3.56*tan(0.03490658503988))/2
Evaluating ... ...
h1 = 0.0715179393905984
STEP 3: Convert Result to Output's Unit
0.0715179393905984 Meter --> No Conversion Required
0.0715179393905984 0.071518 Meter <-- Driver Sight Height

## < 4 Length of Valley Curve Less than Stopping Sight Distance Calculators

Deviation Angle Given Length of Valley Curve Less than Stopping Sight Distance
Deviation Angle = (2*Sight Distance)-(2*Driver Sight Height+(2*Sight Distance*tan(Inclination)))/(Length of Curve)
Inclination Angle given Length of Valley Curve Less than Stopping Sight Distance
Inclination = atan(((Length of Curve-2*Sight Distance)*Deviation Angle+2*Driver Sight Height)/(2*Sight Distance))
Length of Valley Curve Less than Stopping Sight Distance
Length of Curve = 2*Sight Distance-(2*Driver Sight Height+(2*Sight Distance*tan(Inclination)))/(Deviation Angle)
Driver Sight Height given Length of Valley Curve Less than Stopping Sight Distance
Driver Sight Height = ((Length of Curve-2*Sight Distance)*Deviation Angle+2*Sight Distance*tan(Inclination))/2

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

Driver Sight Height = ((Length of Curve-2*Sight Distance)*Deviation Angle+2*Sight Distance*tan(Inclination))/2

## Length of Valley Curve Less than Stopping Sight Distance

The "Length of Valley Curve Less than Stopping Sight Distance" refers to the segment of a road that forms a downward slope or depression (valley) and is shorter than the stopping sight distance required for safe driving. This length indicates a section where the road curvature is such that a driver can see the road ahead within a distance that is less than the stopping sight distance, potentially posing a visibility challenge and requiring caution.

## How to Calculate Driver Sight Height given Length of Valley Curve Less than Stopping Sight Distance?
