SPR-4617: Demonstration of Zero Speed Inertial Profilers

Indiana Department of Transportation (INDOT) pavement smoothness specifications utilize inertial profilers and IRI to evaluate newly constructed concrete pavement. The utilization of current inertial profilers is limited in low-speed zones that include stop signs and traffic lights. Currently, one vendor is producing a “Zero Speed” inertial profiler, and the two other major players in inertial profilers are developing Zero speed inertial profilers. The “Zero Speed” inertial profilers include additional hardware and updated software to better model the motion of the vehicle. This allows collecting more accurate profiles in urban areas that include stop signs and traffic lights. The purpose of this study is to demonstrate the utility of “Zero Speed” inertial profiler in urban areas.
