Advancements in connected and automated vehicle (CAV) technologies present new challenges for Traffic Incident Management (TIM) and emergency responders (ERs), particularly due to limited information sharing among stakeholders. NCHRP Research Report 1104 offers essential resources and communication tools to enhance collaboration and understanding between CAV developers, TIM personnel, and ERs. The report equips responders and those in the TIM community with strategies and insights to effectively engage with the evolving CAV landscape.

The Minnesota Resilience Improvement Plan (RIP) is MnDOT’s first statewide roadmap for strengthening the transportation network against climate-driven hazards such as heavy precipitation, flooding, extreme temperatures, and freeze-thaw cycles. Informed by historical data, future projections, and statewide vulnerability mapping, the plan positions MnDOT and regional partners to leverage roughly \$121 million in PROTECT formula funds while guiding project selection and design through climate-focused criteria. It lays out three pillars—site-specific resilience projects, policy and design updates, and communication and education initiatives—to embed climate considerations into daily practice. Progress will be tracked through performance measures on adaptation, asset condition, and weather impacts, with biennial project-list updates and a comprehensive plan refresh slated for 2026.

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.

Artificial intelligence (AI) has become a powerful force in transportation departments, particularly for managing and streamlining traffic flow. By using real-time data and predictive analytics, AI solutions can ease congestion, decrease travel times, and enhance safety through early hazard detection. In addition, AI-driven simulations offer a cost-effective method for evaluating and refining transportation networks, reducing the need for extensive physical testing.

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.

This report summarizes the proceedings of the 2023 Transportation Asset Management Peer Exchange hosted by the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO). The peer exchange was held in Boston, Massachusetts on July 8-9, 2023.

The Climate Adaptation and Resilience Roadmap serves as ODOTs RIP and was accepted by FHWA in August of 2023. The RIP provides a practical guide to operationalizing climate adaptation and resilience. It draws from climate hazard analysis and outlines strategies and implementation actions that will help ODOT institutionalize climate resilience in the ways the agency plans for, invests in, builds, manages, maintains, and supports the multi-modal transportation system.
