Traverse on Curve

&XUYH 7UDY RQ
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:
5DGLXV
•
: is the distance from the radius point to the
curve.
'HOWD
•
: is the deflection angle.
'HJUHH $UF
•
: is the deflection angle that results in a
100-ft. arc length.
'HJUHH &KRUG
•
a 100-ft. chord length.
The second known part of the curve is defined by one of
the following:
'HOWD
•
: is the deflection angle.
/HQJWK
•
: is the arc length.
&KRUG
•
: is the chord length.
7DQJHQW
•
: is the distance from the PC or PT to the PI.
• 0LG 2UGLQDWH
the center of the curve's length.
([WHUQDO
•
: is the minimum distance between the PI and the curve.
3& 3RLQW
: is the point that defines the beginning of the curve (Point
of Curvature).
$]LPXWK %HDULQJ

of the curve.
Turn: specifies if the curve turns to the Left or Right as you face the
curve from the PC.
R-196
&XUYH
: is the deflection angle that results in
: is the distance between the curve and the chord at
: is the direction of the tangent at the beginning
