Concept explainers

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.

Expert Solution

Step 1

Given data

Design speed (v)=5 miles/hr

Design speed (v)= $5 \times 1.609$

Design speed (v)=8.047kmph

G=Deflection angle

$G = G_{1} - G_{2} G = (- 2.6) - 1.0 G = (-) 3.6 %$
