COVID-19 reshaped mobility patterns worldwide, affecting walking, driving and public transit use, finds a new study published in The Lancet Public Health. The research, led by an international team including researchers in the Brown School at Washington University in St. Louis, analyzed data from nearly 300 cities to understand how urban transportation habits adapted during the pandemic.
A groundbreaking review article delves into the critical challenges facing electric vehicle (EV) battery technology, offering insights into current research trends and future advancements. The study examines the performance, safety, and environmental impact of various battery types, including lithium-ion and solid-state batteries. It also explores innovative management techniques and highlights the importance of developing cost-effective, sustainable, and safe battery solutions to support the growth of electric mobility.
Nobody enjoys sitting in traffic, especially during the holidays. Hesham Rakha, director for the Center for Sustainable Mobility at the Virginia Tech Transportation Institute, said if you are going to avoid traffic when traveling for Thanksgiving and Christmas, “you’re going to have to make some sacrifices.” “You have to choose temporal times where people don’t want to travel,” Rakha said.
The Korea Institute of Machinery & Materials (KIMM) has successfully developed an advanced automated mooring system aimed at enhancing the safety and efficiency of docking operations for autonomous vessels. Designed to overcome the limitations of conventional wire-based mooring methods, this innovative system is projected to be commercially available by 2025, significantly contributing to the progress of smart port technology.
Jie Xiao, University of Washington professor of mechanical engineering, talks about batteries and how academia can help support the growing domestic battery manufacturing industry.
Teams from Northern Arizona University and the Salt River Project collaborated on several research projects, including ones aimed at protecting the Salt and Verde River watersheds and ensuring the power grid can handle the increasing number of electric vehicles on the road.
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.
The airline says it will continue to operate while it restructures its debt. ...
New York City's 2019 ride-hailing surcharge cut overall taxi and ride-share trips by 11 percent in Manhattan but failed to reduce traffic congestion, a key goal of the policy, according to a new NYU Tandon School of Engineering study published in Transportation Research Part A.“While this surcharge differs from the MTA's proposed congestion pricing plan, the study's findings can contribute to the current discourse,” said Daniel Vignon, who led the research.
An architectural project in Sutton aims to tackle the housing crisis while promoting sustainable development and social inclusion.
Batteries in electric vehicles can fail quickly, sometimes catching fire without much warning. Sandia National Laboratories is working to detect these failures early and provide sufficient warning time to vehicle occupants.
How do you electrify a populous city’s transit without destabilizing its grid? New research into Beijing’s 27,000-bus system explores using depots to generate a solar power.
Dr. Nathan Johnson, a systems engineering professor at Arizona State University and an expert in innovative energy solutions. He shares his vision for a sustainable energy future and outlines his team’s six-step approach to renewable energy projects.
“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.

Irvine, Calif., Oct. 31, 2024 — By creating a new way for light and matter to interact, researchers at the University of California, Irvine have enabled the manufacturing of ultrathin silicon solar cells that could help spread the energy-converting technology to a vast range of applications, including thermoelectric clothing and onboard vehicle and device charging.
The Department of Transportation said the final federal rule went into effect on Monday, coming ahead of a busy upcoming holiday travel season. ...
Lithium-sulfur batteries have never lived up to their potential as the next generation of renewable batteries for electric vehicles and other devices. But SMU mechanical engineer Donghai Wang and his research team have found a way to make these Li-S batteries last longer – with higher energy levels – than existing renewable batteries. The research team has been able to prevent Li-S batteries from producing an unwanted side effect known as polysulfide dissolution that appears over time, shortening their lifespan.
Originally developed for electric cars, nowadays they supply mobile phone antennas with electricity, and tomorrow perhaps entire districts: The salt battery is a safe and long-lasting battery technology with huge potential. Empa researchers are collaborating with an industrial partner to further develop these special batteries.
