This plan identifies risk-based analyses and processes to support the efficient allocation of New Hampshire DOT's resources. Its goal is to maintain assets in a State of Good Repair and reduce any potential system risks. The New Hampshire DOT worked with the state's four metropolitan planning organizations to provide a 10-year roadmap for the strategic management of NHS bridge and pavement assets.

This article, published by the Environmental Protection Agency, answers questions surrounding six common myths about electric vehicles. It provides straightforward answers and offers up additional resources for further investigation. The six myths are:

• Myth #1: Electric vehicles are worse for the climate than gasoline cars because of the power plant emissions.
• Myth #2: Electric vehicles don’t have enough range to handle daily travel demands.
• Myth #3: Electric vehicles only come as sedans.
• Myth #4: There is nowhere to charge.
• Myth #5: Electric vehicles are worse for the climate than gasoline cars because of battery manufacturing.
• Myth #6: Electric vehicles are not as safe as comparable gasoline vehicles.

"When targets matter, they drive transportation agency decisions and actions."

The TRB National Cooperative Highway Research Program's NCHRP Research Report 993, titled "Managing Performance to Enhance Decision-Making: Making Targets Matter," presents various feedback enhancement strategies. It includes case studies demonstrating how agencies successfully integrate feedback based on data and people into their decision-making processes. These processes span long-term strategic planning, medium-term program development, and daily operations.

NMDOT's 2022 TAMP provides an assessment of the condition of pavements and bridges on the Interstate and National Highway System and identifies future performance gaps based on current and anticipated finances and asset conditions. It also includes a description of the project selection process, how cost estimates are determined, the details of NMDOT’s financial plan, and an assessment of the risks inherent in managing such an expansive set of assets.

The Indiana Department of Transportation (INDOT) has developed a TAMP with the goal is to achieve and sustain a desired state of good repair over the life cycle of the assets at a practical cost. The 10-year outlook of the 2022 TAMP streamlines with INDOT's 20-year plan to fully fund the asset management plan for bridges, large culverts, and roads.

This study considers existing intelligent highways components, such as sensors and remote surveys, and the data they collect, and how their use might be expanded to other purposes, such as incident response.

This policy brief describes the GHG Mitigation Measures Policy Directive adopted by the Transportation Commission for Colorado DOT in May 2022. The policy establishes ongoing processes for measuring, validating, and reporting GHG mitigation measures as set out in a December 2021 standard.

This report details the deployment of state-of-the-art technology for the inspection of highway infrastructure during construction and maintenance activities.

The updated 2022 Mississippi TAMP (further revised January 2023) outlines the guiding strategies for TAM efforts at MDOT. Under Managing Risk (chapter 5), MDOT's 2022 TAMP now includes a new section, "Risk in the TAMP", detailing MDOT's risk performance gap analysis efforts. Under Financial Plan (chapter 7), the 2022 TAMP includes a new section for "Overall Distribution of Revenue".

This document, developed through the National Cooperative Highway Research Program (NCHRP) Project 20-24(127), builds on a review of TPM practice and phased practitioner outreach to identify, synthesize, and prioritize common challenges and issues associated with TPM implementation. It presents a TPM Action Plan designed to help agencies meet these challenges; the Action Plan is described in the following sections.

This textbook provides a framework for infrastructure asset management decision-making, including how data are used to build models and assessing the effectiveness of investments.
