To us instructions

To use enter the design speed and emax. The running speed and fmax will be calculated using the regression equations on sheet 2. The radius minimum and radius at the running speed will be calculated. Enter the actual degree of curve and the eact will be calculated. The tangent runout and runoff will be calculated using the transition gradient% calculated by regression show on sheet 2. The stations of the various points on the transition are calculated on the second page of sheet 1.
