Time given Length of Valley Curve and Design Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time = Length of Curve/Design Speed
t = L_s/v
This formula uses 3 Variables

Variables Used

Time - (Measured in Second) - The time it takes for a vehicle or object to traverse the length of the valley curve while experiencing a specific rate of change of acceleration.
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.
Design Speed - (Measured in Meter per Second) - Design speed refers to the intended or planned operating speed for a particular section of a roadway or railway.

STEP 1: Convert Input(s) to Base Unit

Length of Curve: 12.71876 Meter --> 12.71876 Meter No Conversion Required
Design Speed: 5 Meter per Second --> 5 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t = L_s/v --> 12.71876/5

Evaluating ... ...

t = 2.543752

Design Speed given Length of Valley Curve

LaTeX Go Design Speed = (Length of Curve*Radius of Curve*Rate of Change of Acceleration)^(1/3)

Radius of Curve given Length of Valley Curve

LaTeX Go Radius of Curve = (Design Speed^3)/(Length of Curve*Rate of Change of Acceleration)

Rate of Change of Acceleration

LaTeX Go Rate of Change of Acceleration = (Design Speed^3)/(Length of Curve*Radius of Curve)

Length of Valley Curve given Time and Design Speed

LaTeX Go Length of Curve = Design Speed*Time

Time given Length of Valley Curve and Design Speed Formula

LaTeX Go

Time = Length of Curve/Design Speed
t = L_s/v

Length of the summit curve

The term "length of the valley curve" is usually used in the field of highway or railway engineering to describe a specific feature in the roadway design. It refers to the distance along the road or track where the alignment changes from an upward slope (crest) to a downward slope (sag), which creates a concave or valley-like shape.
