On a monthly basis, each State is required to report to the Federal Highway Administration (FHWA), the amount of gallons taxed by that state. This data is analyzed and compiled by FHWA staff. The data on the amount of on-highway fuel use for each State is then used to attribute federal revenue to each State. Yearly, the FHWA, Office of Policy, prov

The Weekly Traffic Volume Report estimates the vehicle miles traveled (VMT) for interstate highways and how the total travel measured by VMT compares with travel that occurred in the same week of the previous year. The VMT is further split into passenger vehicle and truck components. The information gives new insights into the effect on traffic by

Successes in Stewardship is a Federal Highway Administration (FHWA) bimonthly newsletter highlighting current best practices in stewardship and environmental review from around the country.
Many steel reinforced concrete bridges must endure exposure to corrosive materials such as deicing salts and salt water. Unmitigated, these materials accelerate corrosion and significantly reduce the service life of bridges. While corrosion-resistant materials can be chosen during the design phase, addressing corrosion in existing structures can be

The Federal Highway Administration (FHWA) developed InfoTechnology™ to fill the knowledge gap between highway infrastructure practitioners/asset managers dealing with highway infrastructure performance challenges and researchers developing and refining nondestructive evaluation (NDE) technologies to support their efforts.
Concrete overlays leverage the investment already made in the existing pavement structure while potentially reducing the need for significant preservation activities and reducing lane closure durations. This case study summarizes the design, construction, and performance of bonded and unbonded concrete overlays on existing continuously reinforced c

This report summarizes the key findings of the 2020 Intelligent Transportation Systems (ITS) Deployment Tracking Survey (DTS). Since 1997, the ITS Joint Program Office (JPO) has used the DTS on an ongoing basis to collect information about ITS deployment in metropolitan areas across the United States by surveying state and local transportation agen

Traditional traffic counts have long been utilized by U.S. DOT, the states, and MPOs to determine volumes of traffic. Recent developments in connected technologies have provided the potential for probe-based, or passive, measurement of traffic volumes that combines information on specific vehicles and advanced analytics algorithms to estimate AADT

Traffic management systems (TMSs) and their operating centers, traffic management centers, support real-time and offline functions, services, actions, and activities—as well as related tasks and decisions (e.g., administrative actions and condition reports). In this context, decision-support tools (DSTs) are not generally used as standalone solutio

Traffic Volume Trends is a monthly report based on hourly traffic count data reported by the States. These data are collected at approximately 5,000 continuous traffic counting locations nationwide and are used to estimate the percent change in traffic for the current month compared with the same month in the previous year. Estimates are re-adjuste

Lightweight concrete has been used successfully for the construction of bridges since soon after commercial production of lightweight aggregate began in the United States in 1920. Design provisions for lightweight concrete have been provided in AASHTO specifications for over 35 years. However, the material is not commonly used for bridge constructi
