This is a companion document to NCHRP Report 1122: Implementing Machine Learning at State Departments of Transportation.

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.

NMDOT's Resilience Improvement Plan (RIP) evaluates the risks that current and future weather events and natural disasters pose to New Mexico's surface transportation system. Based on this analysis, the document outlines a prioritized investment plan for projects across NMDOT districts to enhance the resilience of the surface transportation system. It also presents suggestions for ongoing interagency collaboration and provides recommendations for future updates to the RIP, as well as policies, practices, and actions to embed resilience within NMDOT. The NMDOT RIP is methodologically aligned with the New Mexico Hazard Mitigation Plan and takes into account the well-being of all New Mexicans. This includes assessing evacuation routes, critical destinations, and the increased vulnerability of socially disadvantaged populations. The plan is also informed by related resilience and climate planning efforts undertaken by other state agencies in New Mexico, tribal partners, neighboring states, and local jurisdictions.

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.

The Iowa Resilience Improvement Plan (RIP) outlines key components designed to bolster the state’s transportation system resilience:

Climate Consideration: This includes a review of Iowa’s climate over time, evaluations of billion-dollar natural disasters, and analysis of near-term and long-term climate and weather trends.

Hazard Summary and Assessment: The plan details natural and other hazards that could impact Iowa’s transportation infrastructure, incorporating a risk prioritization matrix and priority hazard analysis.

Resiliency Toolbox: It identifies natural and man-made countermeasures to mitigate hazards, discusses potential tools like policy adaptations, research, and co-beneficial improvements, and outlines strategies to enhance transportation resilience across the state.

Targeted Corridors and Segments: The plan lists specific corridors or segments of Iowa’s transportation network that are particularly susceptible to flooding and other natural disasters, emphasizing areas of high risk.

The Delaware Department of Transportation (DelDOT) has developed this Delaware Resilience Improvement Plan (DRIP) as a strategic blueprint for thoughtful investment in critical infrastructure. It aims to proactively identify and address action items, and to customize both adaptation and mitigation measures to meet the agency's resilience objectives. The DRIP was crafted in compliance with federal standards and directives as outlined in the PROTECT Formula Program Implementation Guidance issued by the FHWA in 2022 (INFORMATION: Promoting Resilient Operations for Transformative, Efficient, and Cost-Saving Transportation (PROTECT) Formula Program Implementation Guidance (dot.gov)). It was specifically shaped under Section G (3), which pertains to the formulation of Resilience Improvement Plans.

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.
