Point and Line Features,blication. Lines and curves, much like points, they too can be generated by fairly much the same means as points. Thus, the procedures to be presented in this chapter are those that pertain to the points and lines that can be created by various constructions with the aide of coordinate geometry. Curves are to be presented in subsequent chapters.

Spiral Transition Curves,n the direction of the turn. Since an automobile or train cannot lean in such a manner, the engineers and contractors elevate one end of the travel path to induce such a tilt to the traveling vehicle.

Vertical Parabolic Curves,eatures), the real earth within the confines of this plane is not flat. Thus, provision must be made to account for a third dimension Z (elevation). Thus, in this chapter we are to present certain computing procedures that address the vertical positioning of routes along a horizontal alignment.

Tobias Kollmann,Andreas Kuckertz the . subroutine addressed in Chap. ., and in which the argument . should be set to 3 for a quadratic, and to 4 for a cubic curve. This procedure may also be used to create other curve shapes by increasing the number of points.

Online Shopping and Human Factors point with the rotational direction remaining the same, clockwise or counterclockwise, these curves are referred to as compound curves. If the rotational direction from one curve into another curve changes direction, these curves are referred to as reversed curves.
