WebJun 1, 2024 · Other researchers have focused on the use of smartphone sensors for evaluating the roughness of the pavement surface and by using the vertical acceleration recorded by a mobile device in a car , . The International Roughness Index (IRI) was the more investigated parameter and the road surface condition classified by IRI-proxy factors. WebThe development of roughness meters was followed with considerable interest by road authorities in Australia, and in 1969 the National Association of Australian State Road Authorities (NAASRA) and ARRB established a joint subcommittee to report on currently available systems with a view to adopting a system for use in Australia.
The IRI is calculated from the road profile. This profile can be measured in several different ways. The most common measurements are with Class 1 instruments, capable of directly measuring the road profile, and Class 3 instruments, which use correlation equations. Using World Bank terminology, these correspond to Information Quality Level (IQL) 1 and IQL-3 devices, representing the relative accuracy of the measurements. A common misconception is that the 80 km/h used i… WebThe World Bank established the International Road Roughness Index (IRI) as a standard to measure road roughness. ... 1978 - Australia - Measurement of Road Roughness in Australia 1128 Downloads 615.83 KB 25-06-2024 Report on field trials of the ...
Webrange for roughness is 0.5 m to 50 m (PIARC). The roughness test result is a measure of the riding quality of pavement surfaces in response to that longitudinal profile. Roughness, as determined by the Laser Pofiler, is reported in 100 m intervals in dimensionless units as International Roughness Index (IRI, m/km). By using the
WebSince 1990, the FHWA has required the state DOT’s to report road roughness from their PMS on the International Roughness Index (IRI) scale for inclusion in the Highway Performance Monitoring System.
