Preliminary assessment of ALOS/PALSAR images for the international roughness index estimation
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015This article evaluates the relationship between SAR backscattering coefficients and the International Roughness Index (IRI). We used full-polarized ALOS/PALSAR amplitude images and field data gathered using laser sensors on-board of vehicles. We also evaluated LANDSAT-5/TM images for comparison.

Effects of the International Roughness Index and Rut Depth on Crash Rates
Transportation Research Record: Journal of the Transportation Research Board, 2018Pavement distresses directly affect ride quality, and indirectly contribute to driver distraction, vehicle operation, and accidents. In this study, analysis was performed on highways in the states of Arizona, North Carolina, and Maryland to investigate the relationship between accident rate and pavement ride quality (roughness) and rut depth.

Estimating International Roughness Index from noisy profilograph measurements
2009 IEEE Intrumentation and Measurement Technology Conference, 2009In this paper, we propose a method for estimating the international roughness index (IRI) of a pavement profile using data collected by a computerized profilograph making noisy measurements. We begin by modeling the pavement as a nonstationary stochastic process and show that, despite this nonstationarity, we can exploit the design of the profilograph ...

Relation Between Seated Person Vibrations and the International Roughness Index
Transportation Research Record: Journal of the Transportation Research Board, 2023Vertical vehicle feet/floor interface vibrations are typically not used to indirectly estimate road roughness. The relation for vehicle floor vibrations, the International Roughness Index (IRI), vehicle speed, and road roughness vertical displacement spectrum according to the ISO 8608: 2016 standard was previously derived only for the simulation of a ...

Using the International Roughness Index for Profilograph Trace Reduction
Transportation Research Record: Journal of the Transportation Research Board, 1996Current Louisiana acceptance specifications for 100 percent payment require Profile Indexes (PIs) completed pavement surface to as low as 3.0 in./mi for flexible pavements and 6.0 in./mi for rigid pavements. These acceptance specifications are currently among the most stringent in the United States. Requiring an acceptance PI value of less than 7.0 in./

Investigation and Analysis of International Roughness Index at National Freeway in Taiwan
Applied Mechanics and Materials, 2015Taiwan's National Freeway plays an important role in Taiwan's transportation, it is convenient to go to anywhere through a series of north-south and east-west road networks, from this we can see, the freeway road quality is a project that always need to be concerned, and how to enhance the pavement quality of National Freeway will be the main subject ...

Feasibility of Modernizing the Acceptable International Roughness Index Value
Transportation Research Record: Journal of the Transportation Research BoardThe U.S. National Highway System has set a standard for acceptable pavement roughness, measured by the international roughness index (IRI) at less than 2.68 m/km (170 in./mi). This value corresponds to a present serviceability rating (PSR) of 2.5, where half of the highway drivers perceive the pavement ride quality as unacceptable with a repair need ...

Developing Spectrum-Based Models for International Roughness Index and Present Serviceability Index
Journal of Transportation Engineering, 2001This paper presents a theoretical model for determining international roughness index (IRI) and present serviceability index (PSI) in term of power spectral density (PSD) roughness. Frequency response functions of quarter-car model and CHOLE-type profilometer are obtained by means of stochastic process theory.
