Length of Curve given Change in Grade where S is more than L Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Curve = 2*Sight Distance SSD-(800*Height of Vertical Curves/Change in Grade)
L_c = 2*SD-(800*h/N)
This formula uses 4 Variables

Variables Used

Length of Curve - (Measured in Meter) - Length of Curve is determined by the permissible rate of change of grade or from centrifugal consideration as appropriate.
Sight Distance SSD - (Measured in Meter) - Sight Distance SSD 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.
Height of Vertical Curves - (Measured in Meter) - Height of Vertical Curves is the distance between the lowest and highest points of a person standing upright.
Change in Grade - Change in grade is the algebraic sum of two grades in the vertical curve. It is expressed in percentage.

STEP 1: Convert Input(s) to Base Unit

Sight Distance SSD: 490 Meter --> 490 Meter No Conversion Required
Height of Vertical Curves: 1.7 Meter --> 1.7 Meter No Conversion Required
Change in Grade: 3.6 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_c = 2*SD-(800*h/N) --> 2*490-(800*1.7/3.6)

Evaluating ... ...

L_c = 602.222222222222

STEP 3: Convert Result to Output's Unit

602.222222222222 Meter --> No Conversion Required

FINAL ANSWER

602.222222222222 ≈ 602.2222 Meter <-- Length of Curve

FAQ

What is Length of Curve given Change in Grade where S is more than L?

The Length of Curve given Change in Grade where S is more than L is defined for the condition where the sight distance is more than length of curve. The change in grade is the algebraic sum of both upgrade and downgrade and is represented as L_c = 2*SD-(800*h/N) or Length of Curve = 2*Sight Distance SSD-(800*Height of Vertical Curves/Change in Grade). Sight Distance SSD 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, Height of Vertical Curves is the distance between the lowest and highest points of a person standing upright & Change in grade is the algebraic sum of two grades in the vertical curve. It is expressed in percentage.

How to calculate Length of Curve given Change in Grade where S is more than L?

The Length of Curve given Change in Grade where S is more than L is defined for the condition where the sight distance is more than length of curve. The change in grade is the algebraic sum of both upgrade and downgrade is calculated using Length of Curve = 2*Sight Distance SSD-(800*Height of Vertical Curves/Change in Grade). To calculate Length of Curve given Change in Grade where S is more than L, you need Sight Distance SSD (SD), Height of Vertical Curves (h) & Change in Grade (N). With our tool, you need to enter the respective value for Sight Distance SSD, Height of Vertical Curves & Change in Grade and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Length of Curve?

In this formula, Length of Curve uses Sight Distance SSD, Height of Vertical Curves & Change in Grade. We can use 3 other way(s) to calculate the same, which is/are as follows -

Length of Curve = ((Upgrade)-(Downgrade))*Vehicle Velocity^2/(100*Allowable Centrifugal Acceleration)
Length of Curve = 2*Sight Distance SSD-(200*(sqrt(Height of Observer)+sqrt(Height of Object))^2)/((Upgrade)-(Downgrade))
Length of Curve = 2*Sight Distance SSD-(800*Height of Vertical Curves/((Upgrade)-(Downgrade)))
