Crashes at highway-rail grade crossings are one of the leading causes of railroad-related deaths. According to FRA data, in 2017, there were more than 2,100 crashes resulting in 273 fatalities. Since 2009 crashes have occurred at a fairly constant rate. The federal government provides states funding to improve grade-crossing safety through FHWA’s Section 130 Program. […]
The first National Roundabout Week will take place the third week of September (17th – 21st). The purpose of NRW will be to raise awareness about roundabouts and to provide a national platform to share the successes that state, local and tribal transportation agencies have had with them. FHWA will be using their social media […]
The Interactive Highway Safety Design Model (IHSDM) is a suite of software analysis tools used to evaluate the safety and operational effects of geometric design decisions on highways.
The overall objectives of this study were to: Identify and explore alternative safety data sources and analysis perspectives Demonstrate the potential utility of these alternative approaches in increasing understanding of precipitating events and predisposing factors for crashes occurring on horizontal curves and at unsignalized intersections along rural two-lane roads.
This report documents the results and conclusions of an initial experiment that examined human factors issues in the use of adaptive cruise control (ACC) and a hypothetical cooperative ACC (CACC), which is an ACC system enhanced with vehicle-to-vehicle (V2V) communications to share information on speed, brake position, and distance between vehicles.
Caitlin Hughes, director of the Federal Highway Administration’s office of freight management and logistics, noted in a presentation at the American Association of State Highway and Transportation Officials 2018 Joint Policy Committee meeting in Spokane, Washington on July 18 that a nationwide truck parking survey now expected to start this August is going to be […]

The U.S. Department of Transportation’s Federal Highway Administration (FHWA) today launched a series of meetings with key stakeholders to discuss the ramifications of automated vehicles on U.S. roads. The “national dialogue” meetings are being held across the country to engage a diverse group of stakeholders from industry and the public sector to understand the key […]
U.S. DOT Federal Highway Administration: Traffic Volume Trends is a monthly report based on hourly traffic count data reported by the States. These data are collected at approximately 4,000 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 […]
The modern highway system has experienced considerable changes since the interstate system and other limited access highways were first designed and constructed in the mid-1900s. Population movement outside of cities and the increased movement of passenger and freight traffic have led to increased congestion and necessitated new approaches for maintaining mobility. Mobility and capacity enhancements, […]
