Sight Distance More than Length of Summit Curve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sight Distance = Length of Curve*Deviation Angle+((sqrt(2*Driver Sight Height)+sqrt(2*The Height of The Obstruction))^2)/2
S = L_s*N+((sqrt(2*h₁)+sqrt(2*h₂))^2)/2
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

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.
Deviation Angle - (Measured in Radian) - Deviation Angle is the angle between the reference direction and the observed direction.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Length of Curve: 7 Meter --> 7 Meter No Conversion Required
Deviation Angle: 0.88 Radian --> 0.88 Radian No Conversion Required
Driver Sight Height: 0.75 Meter --> 0.75 Meter No Conversion Required
The Height of The Obstruction: 0.36 Meter --> 0.36 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = L_s*N+((sqrt(2*h₁)+sqrt(2*h₂))^2)/2 --> 7*0.88+((sqrt(2*0.75)+sqrt(2*0.36))^2)/2

Evaluating ... ...

S = 8.30923048454133

STEP 3: Convert Result to Output's Unit

8.30923048454133 Meter --> No Conversion Required

FINAL ANSWER

8.30923048454133 ≈ 8.30923 Meter <-- Sight Distance

< 3 Length of Summit Curve Less than Sight Distance Calculators

Deviation Angle given Length of Summit Curve Less than Sight Distance

Go Deviation Angle = 2*Sight Distance-((sqrt(2*Driver Sight Height)+sqrt(2*The Height of The Obstruction))^2)/Length of Curve

Length of Summit Curve Less than Sight Distance

Go Length of Curve = 2*Sight Distance-((sqrt(2*Driver Sight Height)+sqrt(2*The Height of The Obstruction))^2)/Deviation Angle

Sight Distance More than Length of Summit Curve

Go Sight Distance = Length of Curve*Deviation Angle+((sqrt(2*Driver Sight Height)+sqrt(2*The Height of The Obstruction))^2)/2

Sight Distance More than Length of Summit Curve Formula

Sight Distance = Length of Curve*Deviation Angle+((sqrt(2*Driver Sight Height)+sqrt(2*The Height of The Obstruction))^2)/2
S = L_s*N+((sqrt(2*h₁)+sqrt(2*h₂))^2)/2
