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

This report describes Machine-to-Machine service architecture and how it is evolving over the next several years. Nearly 50 billion Machine-to-Machine (M2M) devices are predicted to be deployed by all sectors by 2025. The largest impediment to M2M deployment in the transportation sector is largely life cycle cost, which is driven by stringent desig

Two types of alkali-aggregate reaction (AAR) are currently recognized depending on the nature of the reactive mineral; these are alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR). Both types of reaction can result in expansion and cracking of concrete elements, leading to a reduction in the service life of concrete structures. This h

The Urban Congestion Report (UCR) is produced on a quarterly basis and characterizes the most recent traffic congestion and reliability trends at the national and city level. Each quarterly UCR compares data from the most recent three months to the same three months in the previous year.
Some of the most pervasive sources of noise in the environment come from transportation systems. Highway traffic noise is a dominant noise source in urban and rural environments. In response to the problems associated with highway traffic noise, the United States Code of Federal Regulations Part 772 (23 CFR 772), "Procedures for Abatement of Highwa

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

This report describes an existing lightweight bridge decking system that is being refined for use on moveable bridges such as bascule spans. The deck is a 5-inch-deep section consisting of fiber-reinforced polymer materials and high-strength grout. Fabrication steps have been simplified, global behavior and local details have been analyzed, and con

Transportation system management and operations (M&O) coordinates systems to make them more efficient, more convenient, more reliable, safer, and easier to use. M&O strategies make systems work better, allowing us to do more with less – less congestion, less money, less fuel, and less frustration. They support livability by increasing travel choice
