In September 2022, the Department of Transportation (DOT) awarded $1.5 billion in discretionary grants to fund nationally and regionally significant freight and highway projects through the Infrastructure for Rebuilding America (INFRA) program. In fiscal year 2022, DOT combined some phases of the INFRA grant award process with those of two other discretionary grant programs. Specifically, […]
Highway IDEA is one of three IDEA programs managed by the Transportation Research Board (TRB) to foster innovation in highway and intermodal surface transportation systems. Highway IDEA nurtures new concepts for technologies, methods, and processes for application to highway systems in broad technical areas such as highway design and construction, materials, operations, and maintenance.

Nearly one-third of residences in the U.S. are multi-unit dwellings (MUDs), e.g., apartments and condominiums, and MUDs with five or more units account for approximately 45% of rental households. While 80% of EV charging takes place at home, less than 5% of home charging takes place at MUDs. With public electric vehicle (EV) charging still […]
There are over 590,000 bridges dispersed across the roadway network that stretches across the United States alone. Each bridge with a length of 20 feet or greater must be inspected at least once every 24 months, according to the Federal Highway Act (FHWA) of 1968. This research developed an artificial intelligence (AI)-based framework for bridge […]
Walking, biking, and other sustainable modes of transportation are critical options in communities throughout the United States, particularly for economically disadvantaged communities. However, fatalities among pedestrians and bicyclists have been increasing even faster than the overall fatalities among all road users, which has drawn a focus on the safety of vulnerable road users (defined below). […]
The National Highway Traffic Safety Administration has taken the first step toward making impaired-driving prevention technology standard in new passenger vehicles. The Advance Notice of Proposed Rulemaking that NHTSA is announcing today helps fulfill a requirement in the Bipartisan Infrastructure Law and supports the Department’s National Roadway Safety Strategy. Read the full article here.
Risky driving behaviors such as speeding and impaired driving play a critical role in road traffic crashes and contribute to an unsafe transportation environment for Americans traveling both inside and outside vehicles. The 2022 Traffic Safety Culture Index provides insights into understanding public perceptions, attitudes toward, and engagement in unsafe driving behaviors. This report examines patterns of […]
NHTSA has recently issued a projection report of traffic fatalities and the fatality rate per 100 million vehicle miles traveled (VMT) for the first half of 2023 (Early Estimate of Motor Vehicle Traffic Fatalities for the First Half (Jan–Jun) of 2023, Report No. DOT HS 813 514). That report shows an estimated 19,515 people died […]
A new report from the Governors Highway Safety Association (GHSA), with the support of State Farm®, examines traffic safety cameras – an underutilized tool in the fight to reduce dangerous driving behaviors that contribute to more than 100 people dying on U.S. roads every day. The report discusses the benefits of traffic safety cameras that […]
This paper presents a simulation model of the markets for light-duty electric vehicles (EVs) and the associated public charging infrastructure, as well as the network interactions between them. It illustrates the model’s attributes by simulating the effects of federal subsidies for public electric vehicle chargers and of an extension of tax credits for electric vehicles. […]
