Curve Solution
&XUYH &XUYH 6ROXWLRQ or ,
Curve - Horizontal
The Curve Solution screen provides detailed information on a curve
when two parts of the curve are 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 : 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:
• '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 : is the distance between the curve and the chord at
the center of the curve’s length.
• ([WHUQDO : The minimum distance between the PI and the curve.
6ROYH : Computes the details for the horizontal curve.
/D\RXW« : Accesses the Horizontal Curve Layout screen (Page R-189)
where points can be created so the curve can be staked in the field.
7UDYHUVH« : Accesses the Traverse on Curve screen (Page R-196).
