Cayuga Motor Speedway
The Cayuga Motor Speedway received a major face lift and upgrade in 2016, including new infield, grandstands and track expansion. We were approached by our client to produce a high precision TIN model to be used with millimeter accuracy GPS grading equipment. The vertical geometry of the track was based on a profile of control at the base of the track with varying degrees of embankment used to determine the outside edge of the track. We found that by using standard terrain modelling practices, the TIN surface transitions were “too rough” to adhere to the tight tolerances required for a high speed race track. This problem was overcome with use of Civil 3D to densify the TIN information and produce smoother transitions between vertices and adhere to the minimal tolerances required on the project.
We received feedback from our client on the excellent quality and smoothness of the TIN model. The high precision model helped guide our client to work within the tight tolerances and timeline of the project.
