Abstract:The Moving Ahead for Progress in the 21st Century Act (MAP-21), the Fixing America’s Surface Transportation Act, and other current legislation promote the use of performance-based decisions to manage the Nation’s highway system (U.S. Congress 2012, 2015). MAP-21 identified seven national goal areas and established requirements for national performance measures for pavements and bridges and the development and implementation of risk-based transportation asset management plans by State departments of transportation (DOTs) (U.S. Congress 2012). Fulfilling these requirements has helped highway agencies advance data-driven investment decisions that maximize return on public investment in the highway system and maintain a state of good repair for highway infrastructure assets. Although the condition-based performance measures meet the immediate needs under the legislation, FHWA initiated research to explore “next-generation” pavement performance measures (NGPPMs) that are more proactive in driving investment decisions that lead to enhanced long-term performance. FHWA also investigated the feasibility of a methodology to help transportation agencies manage their highway infrastructure as a system rather than a network of individual asset classes. The research was initiated in 2015 as a two-phased effort titled Identification of Effective Next‑Generation Pavement Performance Measures and Asset Management Methodologies To Support MAP-21 Performance Management Requirements (FHWA n.d.a). Phase Ӏ identified eight promising NGPPMs (not currently required under any Federal legislation) highway agencies could use as leading indicators for long-term investment strategizing and decision making, along with two promising transportation asset management methodologies (TAMMs). In phase Ⅱ, after further development and analysis, seven of the promising NGPPMs and one of the proposed TAMMs were piloted at the State level to validate their use. The study also sought to validate the performance measures at the Federal level. This report details phase II.
