Comparative Performance Measurement: Pavement Smoothness
This report presents results of the second in a series of comparative performance measurement efforts sponsored by the American Association of State Highway and Transportation Officials (AASHTO) Standing Committee on Quality (SCOQ), Performance Measurement and Benchmarking Subcommittee. The purpose of these efforts is to identify states that have achieved exemplary performance, find out what practices have contributed to their success, and document these practices for the benefit of other states. This effort focuses on pavement smoothness, and was co-sponsored by the AASHTO Standing Committee on Planning (SCOP) Subcommittee on Transportation Asset Management. Pavement smoothness is an important performance measure for all states – travelers and shippers place high value on it, and several studies (Sime, 2000; Parera, 2002) have concluded that smooth pavement reduces vehicle operating costs. Because of the Federal Highway Administration’s (FHWA) Highway Performance Monitoring System (HPMS) requirements, all states collect and report International Roughness Index (IRI) data for their National Highway System (NHS) roads. Planned changes to HPMS will encourage greater accuracy and consistency in measurement and reporting of IRI. The importance of this measure to states and the availability of relatively consistent data across agencies made pavement smoothness a good candidate for comparative performance measurement.
