Surveyors and engineers have traditionally used the term vertical curve to describe the use of parabolic curves in design work. They are used for transitions from one straight grade to another in designing crowns for pavements, routes such as highways and railways, as well as dam spillways, landscape design and of course roller coasters. Preparing the calculations necessary to use vertical curves are based on a few principles, once those are clearly in mind vertical curves are a breeze. This online course teaches some of the calculations involved in creating and analyzing vertical curves. It is direct in its descriptions of the why and how of these parabolic curves.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
