The aim of this study is to create a manual that will aid airports in establishing and sustaining a procedure for the handover of asset information. This includes the acceptance of new and replacement physical assets vital to major airport stakeholders. Asset information encompasses, but is not limited to, electronic data, blueprints, and operations and maintenance (O&M) details.

The manual should at least cover the following aspects:

• A list of recommended assets and associated data that airports should keep track of;
• The identification and coordination with individuals and entities that use or provide this asset information;
• Best practices for the oversight and documentation of the asset information handover process;
• Case studies showcasing a variety of airport sizes, types, and levels of experience; and
• A narrative aimed at airport executives, discussing how to implement the asset handover process effectively, including the necessary staff support.

This report provides an overview of how state Departments of Transportation (DOTs) are meeting federal requirements for annual reporting on their Transportation Asset Management Plans (TAMPs). The study, conducted in September 2024, analyzes consistency reports from multiple states, examining their approaches to reporting on asset inventory and condition, risks, funding, and narrative explanations. It highlights variability in reporting practices, discusses common elements and best practices, and offers insights into potential improvements for future reporting. The report is useful for state DOT officials, federal highway administrators, and anyone involved in transportation asset management and performance reporting.

The operation of connected and autonomous vehicle (CAV) technology is expected to impact various components such as traffic control devices, markings, signals, guardrails, computing systems, and communication infrastructure, both on a permanent and temporary basis. It is crucial for state transportation departments to pinpoint deficiencies in understanding and expertise, and to ready themselves for the hurdles of deploying CAV technologies while ensuring that the current road network continues to function at a satisfactory service level.

Critical Issues in Transportation: 2024 and Beyond calls for reassessing the role of transportation in addressing major societal challenges and the research that informs the choices that society will need to make in 2024 and coming years. This reassessment is driven by large-scale environmental, public health, and socioeconomic forces. The report focuses on five societal goals: 1) Mitigating and responding to climate change, 2) Promoting equity and inclusion, 3) Increasing road safety, 4) Advancing public health, and 5) Building and sustaining a strong, competitive economy. Transportation is essential for achieving all of these societal goals.

The objective of this research is to develop a guide for state DOTs and other transportation planning agencies to understand, predict, plan for, and adapt to the potential impacts of emerging disruptive technologies. In preparing this guide, the research should identify issues, effects, and opportunities at the intersection of disruptive transportation technologies and organizational performance for senior managers at state DOTs and other transportation planning agencies.

The Massachusetts Department of Transportation (MassDOT) has developed this 2023 update to its Transportation Asset Management Plan (TAMP) to document its progress toward a long-term state-of-good repair (SOGR) in its pavement and bridge assets. This TAMP complies with 23 CFR 515.7, which calls for state departments of transportation (DOTs) to develop and implement a 10-year risk-based asset management plan for pavement and bridge assets on the National Highway System (NHS). MassDOT has chosen to include in the TAMP all pavement and bridges on the NHS (regardless of owner) and all pavement and bridges owned by MassDOT (regardless of NHS status).

NCHRP Research Report 1066 discusses how to assess risks and summarizes 12 studies that demonstrate how to enhance the measurement of risks, quantify risks, and better link risk management processes with the appropriate tools. It provides transportation asset management staff with a primer on the mathematical and statistical concepts underlying quantitative risk assessment; case study applications; and a set of tools and techniques for identifying and evaluating enterprise-, network-, and program-level asset-management-related risks. The report and its appendices build on the AASHTO Guide for Enterprise Risk Management to provide users with practical tools and guidance on implementing them and will be of immediate interest to departments of transportation (DOTs) seeking comprehensive and easily implementable strategies and tools to improve the condition and performance of transportation assets at the national, state, and local levels.

NCHRP Web-Only Document 366: Risk Assessment Techniques for Transportation Asset Management: Appendices.

This document takes an expansive view and considers how pavement and bridge conditions can contribute to system performance areas, such as highway safety, freight mobility, or reliability. The document also considers other impacts, such as how attributes including pavement shoulders, pavement friction, or bridge conditions contribute to highway safety, freight movement, noise reduction, and transportation system resilience. It also includes three fictional transportation asset management plan (TAMP) chapters illustrating how the TAMP could directly support multiple transportation performance objectives. Those chapters are the performance gap analysis, risk assessment, and investment strategies.

"A Guide for Incorporating Maintenance Costs into a Transportation Asset Management Plan" offers transportation agencies a comprehensive approach to include maintenance costs in a risk-based TAMP. This guide provides methodologies for data collection and management, showcases life-cycle planning tools for assessing cost-effectiveness, details strategies for optimizing 10-year investments using benefit-cost analyses, and designs a financial plan blueprint detailing anticipated revenues and investments in capital and maintenance costs on a 10-year horizon.
