The LTIP includes FHWA’s Long-Term Pavement Performance (LTPP) and Long-Term Bridge Performance (LTBP) Programs.In this report, the committee notes important accomplishments of the LTIP during 2019. The most recent LTPP data release includes new longitudinal transverse profile data, updated climate data, and pavement distress metrics and measured pavement loading that feed directly into pavement design software available through the American Association of State Highway and Transportation Officials (AASHTO). Among the other accomplishments for 2019: a number of LTPP data analysis projects addressing predictions of truck and axle loadings were completed; guidance on the use of LTPP traffic data was completed; and, after a lengthy period of technology development, testing, and calibration, the LTBP program is moving forward, to the extent possible with available resources, on NDE data collection on bridge decks.The charge to the committee is to “advise the Federal Highway Administration (FHWA) Infrastructure R&D Program regarding priorities in terms of the technical tools and products that state departments of transportation need to maintain and improve the performance of their pavements, bridges, and other structures.” The committee was established to provide an ongoing review of the LTIP based on annual meetings with FHWA staff and stakeholders.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 972: Development of Safety Performance-Based Guidelines for the Roadside Design Guide provides quantitative safety performance guidance, rather than implicit guidance, which will more effectively communicate design objectives and performance goals, and quantify improvements to safety. This change is complementary to the performance-based practical design approach being promoted by the U.S. Federal Highway Administration, as well as the ongoing efforts to add performance-based design measures to the geometric design process as documented in NCHRP Report 785:Performance-Based Analysis of Geometric Design of Highways and Streets.

The LTIP includes FHWA’s Long-Term Pavement Performance (LTPP) and Long-Term Bridge Performance (LTBP) Programs. In this report, the committee notes important accomplishments of the LTIP during 2018, including the development of a strategic plan for the LTIP, re-initiation of LTPP data collection, and development of an enhanced portal to FHWA’s bridge data, InfoBridge™. The committee’s report stresses the importance of LTPP and LTBP data for developing improved deterioration models that state Departments of Transportation need to meet federal asset management requirements. The committee’s findings and recommendations urge the LTIP to accelerate collection of bridge deck condition data from the field and to begin planning for collection of data on other bridge components, including through accelerated laboratory testing.
