This report guides transportation professionals on the best practices for managing their highway safety infrastructure assets. The methods in the report seek to increase the assets' level of service for a low life-cycle cost, while also mitigating road user risk and improving asset planning, maintenance, and operations.

This presentation describes the calculation tool developed as part of NCHRP 20-100. It provides an overview of the NCHRP Report 866 and highlights the tool's case studies and pilot.

This research provides a framework for ferry asset management that uses asset priority and condition indices to improve on previous ferry asset management processes for North Carolina DOT's ferry division.

New Mexico DOT’s TAMP establishes the current condition of the highway and bridge assets in the state and provides a strategy for maintaining these assets in a state of good repair. The TAMP specifically addresses NMDOT’s plan to achieve the performance goals set forth in recent federal legislation. NMDOT’s TAMP complies with the Federal Highway Administration’s requirements for National Highway System TAMPs. It is also a living document that will be reviewed and updated regularly.

FDOT's asset management practices are mission-driven and are incorporated in the agency’s goals, operating policies, plans, and procedures. This business practice allows FDOT to bring together a variety of disciplines and stakeholders to collaborate on the commitment to sustainable asset stewardship, effective use of resources, and justifications for funding. FDOT uses a system-wide approach built on strong financial planning and investment strategies to create programming, prioritize projects, address risk, and prevent gaps.

ARDOT's initial TAMP was produced in 2018. ARDOT owns and maintains the 12th largest State Highway System in the U.S. ARDOT’s physical assets include pavements, bridges, culverts, rights of way, facilities, and many additional traffic and safety features, such as retaining walls, signs, and guardrails.

North Dakota's 2018 TAMP was created as a first version. The document was did not meet all FAST Act requirements, and a 2019 version subsequently replaced this version before the June 30, 2019 submission deadline for each DOT's TAMP.

On April 30, 2018, LADOTD produced the 2018 Federal NHS Transportation Asset Management Plan, presenting how the state proposes to allocate limited funding resources to bridge and pavement management needs. It provides an overview of the state's TAM principles and tools, existing guiding documents, and current inventory and conditions of pavement and bridges. It then presents performance scenarios, life cycle planning, risk management strategies, and the state's financial plan, as well as investment strategies and proposed asset management enhancements.

This report presents a proposed framework that uses performance measures to quantify the changes in pavement performance in terms of condition, service life, and life-cycle costs. Additionally, the guide identifies alternate performance measures and describes a process for assessing their appropriateness for use in quantifying the effects of preservation treatments on pavement performance. Incorporating these measures in asset management systems would provide a means for selecting the appropriate preservation treatments and optimizing the allocation of resources.

This report documents current practices used by transportation agencies to make investment decisions about low-volume roads. Current transportation asset management practices for low-volume roads typically use asset condition, traffic, and safety metrics to prioritize investment decisions for preservation, maintenance, repair, and replacement projects. However, these metrics do not fully measure the significant value for the wider economy and society that low-volume roads can provide.

This ACRP Impacts on Practice article explores the impact ACRP Research Report 69: Asset and Infrastructure Management for Airports -- Primer and Guidebook has had on managing airport assets. An asset management director at Cincinnati/Northern Kentucky International Airport (CVG) utilized this report to incorporate and directly correlate asset management with CVG’s overall strategic plan. This report explains how to holistically develop an asset management policy as well as asset management strategies, objectives, and plans to achieve the airport’s overall strategic goals. It also provides a roadmap for how to assess and improve an airport's asset management initiatives.

TRB's Transit Cooperative Research Program (TCRP) Research Report 198: The Relationship Between Transit Asset Condition and Service Quality documents the development of a quantitative method for characterizing service quality and demonstrates how this quantitative measure varies with changes in asset condition. It provides guidance on how asset condition and transit service quality relate in terms of investment prioritization.
Three Excel spreadsheets–a simplified Effective Journey Time (EJT) Calculator, a comprehensive EJT Calculator, and a worked example demonstrating the use of the comprehensive EJT Calculator—provide quantitative methods. Transit agencies may use this report and tools to better manage existing transit capital assets and make more efficient and effective investment decisions.
