This new roller coaster, as you will see, has distinct problems at x= 100.5, 137.5 and 149.5. At these points the track is uneven and has gaps or bumps. For these to be dealt with, the dimensions(functions) provided to construct the coaster must be altered. This is done by splining(see Appendix-Definitions). The functions that are being splined, in addition to, their first and second derivatives must be known. The derivatives are taken to match the slope(…showed first 75 words of 673 total…

The key to a successful coaster is to give the rider the sensation of velocity and acceleration. It, ultimately, boils down to velocity control. To achieve this, the hills, curves, dips, straight a ways, braking systems and loops are not randomly designed. This is what makes designing a roller coaster so challenging and interesting.
