Program TRC_TRACCUR adds or removes designed track geometry to a track-file. Input and output to program TRC_TRACCUR are trac- or trax-files.
Input data is read in free format, valid separators between the input values are <space>, <comma>, <tab>, <equal sign> or <carriage return>. The commands can be written both in lower and upper case letters. The operation of the program is controlled by the commands described below; some of the commands also need arguments.
|'R'||Clothoid type of transition curve, the curvature is a linear function of chainage.|
|'S'||Helmert type of transition curve, the curvature has the shape of two second-degree parabolas such that the curvature and its derivative are continuous functions (The Helmert curve is in Germany also known as the Schramm curve).|
Following example: Master.trc_traccurf can be used as a master file:
## ## Input data for program trc_traccur ## INFIL= $gentrc/K0_4a21-n-k.trac UTFIL= test/curv.trac # NXCURV = 4, XCURVE = 20, 64, 75, 85. TCURVE = 'r', 'r', HCURVE = 0,140,-140, ZCURVE = 0, 70, -70,
