The Investment and Economic Analysis Team plans and conducts a program of studies that assess the condition and performance of our nation's highways, bridges, and transit facilities, and provides insight into the implications of various alternative funding scenarios. A blend of expertise in engineering and economics enables this team to break new ground, researching and developing the tools used to conduct these studies to assist the Federal Highway Administration (FHWA)leadership.
Vision: Lead the Federal Highway Administration in the development of effective transportation legislation and policies.
The biennial Condition and Performance (C&P) Report is intended to provide decision makers with an objective appraisal of the physical conditions, operational performances, and financing mechanisms of highways, bridges, and transit systems based both on the current state of these systems and on the projected future state of these systems under a set of alternative future investment scenarios. This report offers a comprehensive, data-driven background to support the development and evaluation of legislative, program, and budget options at all levels of government. It also serves as a primary source of information for national and international news media, transportation associations, and industry.
This 23rd edition of the Status of the Nation’s Highways, Bridges, and Transit: Conditions and Performance Report to Congress (C&P Report) draws primarily on 2014 data. In assessing recent trends, many of the exhibits presented in this report present statistics for the 10 years from 2004 to 2014. Other charts and tables cover different periods, depending on data availability and years of significance for particular data series. The prospective analyses presented in this report generally cover the 20-year period ending in 2034.
Some of the benefits of highway investment are relatively easy to comprehend such as the creation of construction jobs, improved passenger and freight mobility – due to more direct routes, better facilities, and less congestion – and improved access to existing facilities and undeveloped land. But understanding the full, measurable, and long term benefits of highway investment requires focused research. The FHWA seeks to improve our understanding of highway-led employment and productivity growth. This research is valuable for policymakers, State and local officials, academics, and other transportation professionals.
There has been some valuable research undertaken on the effects of investments in transport infrastructure on economic output and the productivity of private capital growth through macroeconomic modeling. The main body of this work is a series of FHWA sponsored research papers by M. Ishaq Nadiri and Theofanis Mamuneas. An associated line of research provides a better measure of the country's capital stock, including highways, one of the key variables used in the modeling effort. More…
Researchers have addressed the specific mechanisms by which infrastructure improvement projects impact a local, regional, or national economy. Unlike benefit-cost analysis, microeconomic economic impact analysis examines how transportation improvements affect the wider economy including local or regional employment patterns, wage levels, business activity, tourism, housing, and even migration patterns. Benefit-cost analysis, by contrast, is limited to the direct benefits and costs of a transportation project on users and nonusers such as changes in travel time, crashes, vehicle operating costs, agency construction costs, and pollution costs. FHWA's work in this area focuses on the effects of congestion, highway spending, and infrastructure improvements. More…
