Abstract:

The Indiana Department of Transportation (INDOT) currently uses inertial profilers for quality assurance and quality control (QA/QC) of newly constructed pavement. However, these profilers face limitations in urban environments characterized by low speeds and stop-and-go traffic. Specifically, their accelerometers struggle to accurately model vehicle movement under these conditions, leading to errors such as artificial localized roughness. Currently, equipment vendors are developing new profiler platforms that incorporate improved temporal and spatial filters, additional sensors, and novel computational methods to enhance performance in urban environments. The purpose of this research is to evaluate the performance of these updated systems in low-speed, stop-and-go urban environments.
