The RSP is capable of real-time, continuous, highway-speed measurements of longitudinal profile elevations, International Roughness Index (IRI), slab faulting, and texture. The longitudinal profile measurement of the RSP is based on the South Dakota method. The system allows the operator to view real-time profile data in both wheel paths in a graphical display allowing for verification of the data during collection.
Mandli recently collaborated with the Wisconsin Department of Transportation to test and certify the RSP against the SurPRO walking profiler. The results showed that the RSP exceeded the Critical Profiler Accuracy Requirements as established by the University of Michigan Transportation Research Institute.
