Using intersection method define horizontal curve.
The intersection point includes coordinate, radius, parameter A1 and A2 of
transition curve. The radius and A1, A2 should not be negative. If radius not being
zero, it will insert an arc with input radius between current point and next point. If A1,
A2 not being zero, it will insert and transition curve with sepecified length between
straight line and the arc.
Don’t mix the intersection point with straight line, circular curve or transition
curve, otherwise the calculation will not be correct.
Follow is the intersection method for definition of horizontal curve steps.
