IRI measurement using dynamic tire pressure sensor with an axle accelerometer

This paper develops a new method to estimate IRI using a dynamic tire pressure sensor (DTPS) inside the tire with an axle accelerometer. This method is based on a physical 2-D dynamic tire model. This paper verifies that speeds above 40 km/h (25 mph) are suitable for both highways and urban roads. Feasibility and repeatability tests were hereby conducted and reported on an airport runway through a certification test that was administered by the Massachusetts Department of Transportation (MassDOT), highways and urban roads. During testing, the accuracy of the new method was equivalent to IRI values measured using the laser profilometers and accelerometers. The newly developed method has the potential to be integrated into vehicle computer systems to form a network wide global health monitoring system of roadways to make the right repair, at the right time, in the right place.
