Abstract: The purpose of this study was to develop and recommend a methodology for evaluating tactical support road situations which will assist in determining appropriate convoy speeds, evaluate the use of bypass routes around lost critical nodes in the infrastructure, and allow the computation of road capacities for determining the logistic vehicle requirements for various tactical scenarios. In this report, an innovative methodology using wavelet transforms is developed. These are used to characterize the vehicle’s vibrational response to ride conditions while traversing nondeformable areas of known surface roughness. Because the mathematical background necessary to understand the application of wavelets to vehicle vibrational response is relatively new, a short review of wavelet mathematics is also included in this report. The development of wavelet technology as an alternative means to characterize the surface roughness of the ride courses through use of the LSV in a similar manner is also described.
