Beginning in 2008, Volkswagen installed software to circumvent emissions testing by turning off the nitrogen oxides (NOx) emissions control system in real-world driving in nearly half a million cars. A new analysis using a tool developed and used by the U.S. Environmental Protection Agency to assess the health and economic impacts related to air quality calculates that a single year of elevated emissions from the affected VW vehicles could lead to as many as 50 premature deaths, 3,000 lost workdays, and $423 million in economic costs.
On most days, the air seems to vibrate at a higher frequency in the labs of West Virginia University’s Center for Alternative Fuels, Engines and Emissions. This week, the work of the center’s engineers, technicians and students is particularly busy. One year after the biggest scandal in automotive history, stakeholders from across the industry are gathering in Morgantown to discuss the future of emissions technology.

The White House recently announced the creation of the Battery500 Consortium, a multidisciplinary group led by the U.S. Department of Energy (DOE) Pacific Northwest National Laboratory (PNNL) and working to reduce the cost of vehicle battery technologies. The Battery500 Consortium will receive an award of up to $10 million per year for five years to drive progress on DOE’s goal of reducing the cost of vehicle battery technologies.
Car emissions is a high-stakes issue, as last year’s Volkswagen scandal demonstrated. Pressure to meet tightening standards led the carmaker to cheat on emissions tests. But wrongdoing aside, how are automakers going to realistically meet future, tougher emissions requirements to reduce their impact on the climate? Researchers report today that a vehicle’s cold start — at least in gasoline-powered cars — is the best target for future design changes.
Imagine, on the streets of the United States, electric vehicles as affordable and convenient as gasoline-powered vehicles. Now imagine that scene taking place in just a few years.
Official government statistics on traffic deaths in southwest India significantly misrepresented the number of pedestrian and motorcycle deaths in the region over a two-year period, casting doubt on the reliability of that country’s government data on traffic fatalities, a study led by researchers at the Johns Hopkins Bloomberg School of Public Health suggests.
Safe driving requires clear central vision and adequate peripheral vision. Glaucoma typically leads to constriction of the visual field, sparing the central vision.
The PNNL-led Battery500 consortium aims to significantly improve upon the batteries that power today’s electric vehicles by nearly tripling the specific energy in lithium batteries.
Researchers at DePaul University found that car rental taxes originally aimed at tourists and business travelers are hurting the car-sharing sector.
It’s called “zipper merge,” and more and more transportation departments around the country are encouraging motorists to use it, according to an Associated Press report by Bill Draper. That’s when a driving lane is closed ahead, and motorists use all available lanes and alternate entry into the open lane when they reach the lane closure. Missouri and Kansas have recently joined Minnesota and Washington in encouraging use of the “zipper merge.”
On a route through some of the nation’s most wild and scenic places, the University of Michigan Solar Car Team hopes to bring back its sixth consecutive victory in the American Solar Challenge.

A team of researchers has found that within 30 years of cougars recolonizing the Eastern U.S., large cats could thin deer populations and reduce vehicle collisions by 22 percent — each year preventing five human fatalities, 680 injuries and avoiding costs of $50 million.
No single assessment tool is able to consistently determine driving ability in people with Alzheimer's disease and mild cognitive impairment, a St. Michael's Hospital research review has found.
The authors recount how Dr. Robert Hubbard, a biomechanical crash engineer, and his brother-in-law, Jim Downing, a racecar driver, joined forces to create the HANS® device, which was designed to prevent the occurrence of shear injuries between the head and neck during high-impact crashes.
Driving is a very complex process. Today, almost half of all drivers on the roadways are over the age of 65. With the decline of cognitive processes in older adults such as Alzheimer’s disease, there is heightened concern for public safety and unsafe driving in this population. Understanding the cognitive factors that inhibit effective driving as well as recognizing older adults who may be at risk for unsafe driving is key.
Driving while talking on a hands-free phone can be as distracting as talking on a hand-held mobile, psychologists at the University of Sussex say.
UCLA-led team of researchers has taken a unique approach to explain the way in which technologies evolve in modern society. Borrowing a technique that biologists might use to study the evolution of plants or animals, the scientists plotted the “births” and “deaths” of every American-made car and truck model from 1896 to 2014.
A new study analyzing traffic stops in Vermont between 2010 and 2015 shows that black and Hispanic drivers are pulled over, searched and arrested far more often than whites, yet white drivers are more likely to be found carrying illegal contraband.
Timothy CaroneElectric car maker Tesla Motors revealed Thursday (June 30) that federal regulators are investigating its autopilot software after a fatal crash involving a semitrailer. The U.S. National Highway Traffic Safety Administration opened the investigation after a man was killed May 7 in Williston, Florida, while driving a Model S with the self-driving mode engaged.
Oxford, June 28, 2016 - Owning a car or bicycle has the strongest influence on how much active travel a Londoner engages in. Car ownership leaves them two to three times less likely to travel actively. And in Outer London, simply owning a bicycle makes you more likely to get 30 minutes of active travel in, even if you have not used it recently. These findings, published in a study in the Journal of Transport & Health, will help policymakers better target interventions to promote active travel.
A small, squishy vehicle equipped with soft wheels rolls over rough terrain and runs under water. Future versions of the versatile vehicle might be suitable for search and rescue missions after disasters, deep space and planet exploration, and manipulating objects during magnetic resonance imaging (MRI), according to its creators at Rutgers University. Their most important innovation is a soft motor that provides torque without bending or extending its housing.
