The FHWA provides guidance on several key aspects of developing a TAMP, including those listed below.

• State TAMPs under BIL.
• 23 CFR Part 667 planning memo.
• TAMP consistency determination guidance.
• Guidance on developing TAMP financial plans.
• Guidance for incorporating risk management into a TAMP.
• Guidance on using life cycle planning to support asset management.

The FHWA also provides information on TPM statutes and regulations on its website. A summary of the six elements used to organize the TPM information is provided with links to the relative information.

A consistent understanding of policy and practice across staff. Alignment includes both vertical alignment, or uniformity between levels of the organizational hierarchy, and horizontal alignment, or standardization across geographic and functional areas

The United States has embraced an equity-oriented strategy in shaping its transportation infrastructure, underscored by an impact-driven framework. In this strategy, funding allocations are purposefully structured to avert the uneven distribution of benefits. This approach is underpinned by regulations and legislative measures crafted to rectify gaps and oversights that have historically led to imbalanced benefit distributions. For instance, the enactment of Title VI stands as an illustration of this approach. Title VI was put into effect to directly tackle challenges stemming from the exclusion of marginalized populations from decision-making processes that receive support from Federal funds.

Over the span of years, a series of Executive Orders emanating from the Presidents of the United States have notably built upon the foundational principles entrenched within the Civil Rights Act. These executive directives have been instrumental in guiding Federal agencies to incorporate policies and procedures that bear direct relevance to civil rights as they execute their operational functions. A prominent illustration of this proactive approach can be found in Executive Order 12898, titled "Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations." Originating in 1994, this pivotal order explicitly charges each Federal agency with a decisive task: to engrain the pursuit of environmental justice within its very mission. This mandate entails the identification and responsible addressing of disproportionately elevated and adverse human health or environmental impacts stemming from the agency's programs, policies, and activities on minority populations and low-income segments. Moving along the timeline, the trajectory of progress continues.

A more recent milestone came in the form of Executive Order 13985, inked in 2021 with the resolute aim of propelling forward racial equity and extending robust support to marginalized communities via the auspices of the federal government. On 2021, the USDOT took a progressive stride by issuing a revamped Environmental Justice Order, officially designated as DOT 5610.2C (USDOT 2021). This document introduces a spectrum of enhancements aimed at refining internal management practices. Within its comprehensive scope, the Order establishes guidance for each Operating Administration and the responsible officials for other DOT components to “determine whether programs, policies, or activities for which they are responsible will have an adverse human health or environmental effect on minority and low-income populations and whether that adverse effect will be disproportionately high” (USDOT 2021).

A type of asset (e.g. pavement, bridge, sign, signal, etc.).

Asset condition measures are fundamental components of transportation asset management. While the specific metric used to assess the condition of each asset can vary greatly, they support common functions within asset management analysis and decision making. Condition measures serve as crucial determinants of an asset's remaining useful service life, performance capabilities, and maintenance needs. They are used to predict when an asset may require maintenance, rehabilitation, repair, renewal, or replacement, enabling agencies to allocate resources efficiently and minimize costly downtime. Moreover, asset condition plays a pivotal role in assessing operational risks associated with asset failure, optimizing maintenance schedules, ensuring regulatory compliance, and evaluating long-term asset strategies, all of which are essential for effective and cost-efficient transportation asset management practices.

Transportation infrastructure deterioration refers to the decline in the physical condition or functionality of transportation assets, such as roads, bridges, railways, and airports, over time due to exposure to factors such as weather, traffic, environmental stressors, and natural wear and tear. It encompasses the deterioration of structural components, surface quality, safety features, and overall operational efficiency.

The ratio of asset preservation, rehabilitation and replacement funding planned over a 10-year period to the total funding required over the same period to achieve and maintain the agency’s desired state of good repair.

Note: This definition was derived from the web version of NCHRP Web-Only Document 335: A Guide to Computation and Use of System Level Valuation of Transportation Assets. More detailed information on asset valuation is available in the full NCHRP Report.

The management stages of an asset including planning, construction, maintenance, rehabilitation, and reconstruction or replacement.

The ability of the asset to fulfill its intended function. While condition is sometimes used as a proxy for performance (e.g. pavements), for other roadway assets such as lighting, safety equipment and bridges, performance may not be adequately evaluated using condition alone. An asset’s service requirement often helps select performance criteria for performance management, forecasting and measurement.
