Traverse on Curve

The Traverse on Curve screen will compute the PT and radius point

for a curve when the tangent azimuth at a PC point is known.

The first known part of the curve is defined by one of the following:

•

: is the distance from the radius point to the

curve.

•

: is the deflection angle.

•

: is the deflection angle that results in a

100-ft. arc length.

•

: is the deflection angle that results in

a 100-ft. chord length.

The second known part of the curve is defined by one of

the following:

•

: is the deflection angle.

•

: is the arc length.

•

: is the chord length.

•

: is the distance from the PC or PT to the PI.

•

: is the distance between the curve and the chord at

the center of the curve’s length.

•

: is the minimum distance between the PI and the curve.

: is the point that defines the beginning of the curve (Point

of Curvature).

/ : is the direction of the tangent at the beginning

of the curve.

Turn

: specifies if the curve turns to the

Left

Right

as you face the

curve from the PC.
