11.1.2 Flat Section Design Line
The flat section design supports the use of the intersection method and the line element method. The intersection
method is based on certain conventions (e.g. single intersection line defines the combination of line elements
within the intersection as gently-rounded-curved-gently), and has certain expression restrictions on the line shape;
while using the line element method, the line shape can be arbitrarily combined, and for complex curves, such as
ovoid lines, multi-intersection curves, virtual intersections, and other data, the line element method is available
to define the line, and the line element method defines the line to support the folded line.

Intersection: The intersection of two adjacent lines (JD1, JD2...)
ZH: the point where the line intersects the first easing curve, i.e. the starting point of the first easing curve.
HY: the point where the first easing curve intersects the circular curve, i.e. the end of the first easing curve.
YH: the point where the circular curve intersects the second easing curve, i.e. the starting point of the second
easing curve.
HZ: the point where the second easing curve intersects the straight line, i.e. the end of the second easing curve.
