PRM_CURV_RAD

The radius of horizontal curvature, entered in feet with positive values being curves to the right in the direction of increasing stations (i.e., Primary Direction) and negative values being curves to the left in the direction of increasing stations.   The default value is tangent.   The RSAPv3 keyword is "PRM_CURV_RAD" and real number between -10,000 and 10,000 are accepted.   Curve radii larger than 10,000 are assumed to be for all intents and purposes to be tangent since the Encroachment Adjustme n t factor for radii greater than 10,000 ft is one.
