Tennessee DOT’s five-year Connected and Automated Vehicle Readiness Action Plan charts how CAV technology will become part of everyday traffic-signal and roadway operations statewide. Grounded in TDOT’s past investments and peer lessons, the plan lays out strategic, actionable steps across planning, policy, funding, engagement, and deployment, with an emphasis on quick safety gains and large-scale interoperability. It also details how TDOT leadership will equip and collaborate with resource-constrained local agencies on infrastructure, operations, and maintenance. Delivering the plan would embed CAV capabilities in TDOT’s standard toolkit and keep Tennessee at the forefront of future CAV investment and expansion.

The United States is experiencing a persistent road safety crisis. Over the past decade, the fatal crash rate per mile traveled has increased, with the sharpest growth occurring among crashes involving vulnerable road users such as pedestrians and bicyclists. U.S. motor vehicle fatality rates are also significantly higher—three to four times greater—than those in other high-income countries in Europe and Asia.

TRB Special Report 354: Tackling the Road Safety Crisis: Saving Lives Through Research and Action, produced by the Transportation Research Board of the National Academies of Sciences, Engineering, and Medicine, examines the scope and causes of this challenge. The study was conducted in response to a request from the Federal Highway Administration, the American Association of State Highway and Transportation Officials, and the Insurance Institute for Highway Safety.

The report outlines a set of recommendations for the U.S. Department of Transportation, including the development of a coordinated, data-driven national road safety research strategy across federally funded safety programs and stronger mechanisms to translate research findings into practice. It also emphasizes the need for systematic research to validate practitioner guidance and retire outdated or unsupported approaches. To advance these goals and elevate national road safety efforts, the study recommends establishing a National Road Safety Research Center.

The Colorado Department of Transportation’s Resilience Improvement Plan (RIP) outlines the agency’s efforts to proactively manage risks and strengthen the state’s transportation infrastructure against natural and human-made hazards. Rooted in lessons from the 2013 flood disaster, the plan highlights CDOT’s Risk and Resilience Program and its commitment to minimizing disruptions and adapting to changing conditions, including those driven by climate change. It also aligns with national initiatives like the PROTECT program under the Bipartisan Infrastructure Law, integrating resilience into both short- and long-term planning. Through ongoing updates and data-driven strategies, the CDOT RIP serves as a framework for maintaining a safe, reliable, and adaptive transportation system.

MDOT has crafted this Transportation Resilience Improvement Plan (TRIP) to direct strategic investments in critical infrastructure, proactively identify and address necessary actions, and ensure that adaptation and mitigation efforts align with MDOT’s resilience goals. This plan complies with federal mandates specified in 23 USC 176 and follows the guidelines set forth in the 2022 FHWA PROTECT Formula Program Implementation Guidance, particularly Section G (3) (FHWA 2022b), dedicated to the formulation of resilience improvement plans. The development of the TRIP by MDOT was designed to be comprehensive, incorporating various modes of transportation and addressing interdependencies and potential co-benefits of projects.

Over the past two decades, machine learning—the leading branch of artificial intelligence—has risen rapidly on the strength of exploding data volumes, cheaper storage and computation, and continual algorithmic breakthroughs. Deep-learning techniques and generative AI systems such as ChatGPT are now transforming day-to-day business practices. Yet state and local transportation agencies are drowning in new data streams faster than they can translate them into actionable insight. TRB’s NCHRP Research Report 1122, *Implementing Machine Learning at State Departments of Transportation: A Guide*, equips DOTs with a primer on promising ML use cases, tools for weighing costs, benefits, risks, and constraints, and a roadmap for fostering the data-driven culture needed to scale these capabilities across transportation programs.

The Michigan Department of Transportation (MDOT) created this Resilience Improvement Plan alongside statewide and regional stakeholders to strengthen Michigan’s transportation networks against climate hazards. Guided by the PROTECT Program established through the 2021 Bipartisan Infrastructure Law, the plan addresses flooding, extreme heat, and coastal erosion. It incorporates input from diverse communities across the state to identify effective, implementable strategies. Ultimately, this approach helps safeguard transportation infrastructure, ensuring continued access to homes, businesses, and essential services throughout Michigan.

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 UDOT Resilience Improvement Plan (RIP) strategically addresses vulnerabilities in Utah’s transportation systems due to current and future weather events and natural disasters. This plan enhances our understanding of these vulnerabilities, informing decision-making and strategic planning to strengthen infrastructure resilience. It provides a comprehensive framework to assess risks, prioritize resources, and implement both immediate and long-range resilience measures. Integrated with Utah's long-range transportation plan, the UDOT RIP ensures robust, effective, and compliant resilience efforts, reinforcing our commitment to safeguarding Utah's transportation infrastructure.

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.
