A letter expressing support and encouragement for the GHG performance standard signed by state transportation agency executives from California, Colorado, Connecticut, Hawaii, Illinois, Minnesota, Oregon, Pennsylvania, Washington State, Vermont, and the District of Columbia.

On July 7, 2022 FHWA announced a Notice of Proposed Rulemaking (NPRM) for states and municipalities to track and reduce greenhouse gas (GHG) emissions. This presentation provides an overview of the proposed rulemaking.

This 2022 synthesis presents examples of transportation agencies' current visualization practices related to highway performance measures. In addition to the published synthesis, a compendium of examples is also available as a separate downloadable file at: https://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_syn_584Presentation.pptx

The 2022 Wyoming TAMP presents the DOT's approach to managing its pavement and bridge assets. It includes sections on pavement and bridge conditions and programs, life-cycle cost analysis, financial planning and investment strategies, and risks to the transportation system. Notably, WYDOT's 2022 TAMP includes a section on Performance Management.

This updated plan is the second TAMP developed for California's transportation system approved by the California Transportation Commission and certified by the FHWA in 2018. It was established in collaboration with hundreds of stakeholders throughout the state. It is expected to improve upon the initial TAMP and allow California to maximize results by managing the life cycle of transportation assets strategically to minimize costs and manage risks.

MDOT’s 2022 TAMP builds off decades of transportation asset management efforts in
Michigan, including the department’s 2019 TAMP. MDOT has used asset management tools to evaluate its network condition since 1997 to guide investment and programming decisions. The Michigan TAMP includes inventory and condition information, documentation of performance measures and targets, a description of the investment strategy and the asset management processes MDOT uses to guide program and project decisions, and financial and performance gap analyses.

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.
