A new study unveils a breakthrough approach to detecting fatigue cracks in Orthotropic steel bridge decks (OSDs) using advanced robotics and deep learning. By automating the identification of internal cracks that are critical to bridge safety, this technology marks a significant leap forward in structural health monitoring.
The Washington Post reports the Maryland Transportation Authority has recommended knocking down both the eastbound and westbound spans of the Chesapeake Bay Bridge and replacing them with new, potentially wider, spans.
After major refurbishments, the old Johannesburg Planetarium has been transformed into the state-of-the-art Wits Anglo American Digital Dome.
“Tell me the numbers, I’ll take care of the politics.” Shashi Nambisan, director of the Transportation Research Center (TRC) at UNLV, recalled a pivotal discussion in the early 1990s with then-County Commissioner Bruce L. Woodbury about the transportation needs of a region on the precipice of substantial growth.
Operators of critical infrastructure are trained to respond to cyberattacks using scale models of water treatment plants, freight rail yards, and more.
Water remains the biggest need for residents in Asheville, North Carolina after Hurricane Helene. ...
A research team examines the extent of damage and associated costs on the 2020 Labor Day wildfires in Washington, Oregon, and California, comparing with the historical impact of megafires in these states.
A study introduces an AI-powered attention-based model for the rapid detection of structural cracks in cross-sea bridges, significantly improving the accuracy and efficiency of maintenance operations. This development offers a fresh approach for ensuring the safety and service life of critical infrastructure.
More than 2 million people were without power in the Southwest United States today due to the aftermath of Hurricane Helene. Research by a team of scientists at the George Washington University... ...
A pivotal study assesses the ice-covered environmental adaptability of overhead contact systems in high-speed railways, vital for ensuring the continuous and safe collection of electrical energy.
The Great Lakes Water Authority (GLWA) has partnered with Wayne State University to develop its Workforce Development and Pipe Management Program, which will help recruit, teach and graduate the next generation of water pipeline managers. The two-year program will begin July 1, 2024, and will be supported by a contract totaling more than $480,000.
New research in the journal Risk Analysis has confirmed that longer freight trains bring with them a higher risk of derailment.
In the aftermath of the collapse of Baltimore’s Frances Scott Key Bridge, authorities are trying to figure out what went wrong and how the collision of the heavily traveled structure with a container cargo ship brought it crumbling down into the Patapsco River. Video shows the massive bridge buckling and tumbling into the water in a matter of seconds. Erin Bell, chair and professor of civil and environmental engineering at the University of New Hampshire, is an expert on bridge construction and points to the structure of the bridge as a possible weakness. She can provide insight into how such a large span could come down so easily—sharing details on how bridges are made, what needs to happen to cause such a devastating collapse and if this could happen with other major bridges.
An interdisciplinary team of experts from the University of Notre Dame, in collaboration with the University of Maryland and University of Utah, have found a way to use artificial intelligence to analyze a household’s passive design characteristics and predict its energy expenses with more than 74 percent accuracy. By combining their findings with demographic data including poverty levels, the researchers have created a comprehensive model for predicting energy burden across 1,402 census tracts and nearly 300,000 households in Chicago.
