A study of the feasibility of road substitution to accelerate the simulation of vehicle use has been conducted using an off-road test (OR test) at the Proving Grounds (PG) as a test case. The purpose of the study was to examine the possibility of accelerating and optimizing the testing conducted at the vehicle proving grounds. This was performed by investigating the similarities in vehicle responses collected from various roads included in the test. The goal was to ultimately reduce the data acquisition period, data analysis as well as the durability cycle replicated in the laboratory environment. The initial study was performed on the data collected for a vehicle durability project. There are ten roads included in the OR test. The vehicle responses collected from these roads were analyzed and compared using the following methods: (1) Time histories and statistical analysis; (2) Cyclic content based on "rainflow counted" histograms; (3) Probability density functions relating the amplitude distribution; (4) Power spectral density; (5) Fatigue analysis. In addition, road profile analyses from a report on the OR test course roughness comparison were used to further verify the results.
