One researcher has developed a clever solution to gather naturalistic driving data. For several years, she has been using a detailed driving simulator to study how participants respond to distraction. However, recently she began taking her research on the.
In the first study of its kind, scientists quantitatively show that electric vehicles will meet the daily travel needs of drivers longer than commonly assumed. They found that batteries that have lost 20 percent of their originally rated energy storage ca.
Sitting in traffic during rush hour is not just frustrating for drivers; it also adds unnecessary greenhouse gas emissions to the atmosphere. Smarter traffic signals can cut greenhouse gas emissions, a new study shows, and authors encourage the uptake of .
Drivers trying to get to work or home in a hurry know traffic congestion wastes a lot of time, but it also wastes a lot of fuel. In 2011, congestion caused people in US urban areas to travel an extra 5.5 billion hours and purchase an extra 2.9 billion gal.
American researchers are calling upon police in all states to improve their reporting of crashes involving vehicles and bicycles. Currently, details on crashes are handwritten by police on paper and there are few bicycle-relevant codes. The researchers ca.
Punishments for drivers whose blood alcohol content is measured above legal thresholds for impairment have reduced the likelihood of repeat offenses, says an economist. To further discourage drunk driving, the researcher suggests lowering the thresholds a.
Researchers have created DARTE (Database of Road Transportation Emissions), a new U.S. nationwide data inventory that can help to provide this crucial information..
Unlike other hydrogen fuel production methods that rely on highly processed sugars, the team used dirty biomass -- the husks and stalks of corn plants -- to create their fuel. This not only reduces the initial expense of creating the fuel, it enables the .
The success of electric vehicle networks depends on economical vehicles – and efficient power grids. Existing power lines were not designed for the loads generated by electric vehicles. Researchers have developed prototype software to show grid oper.
How can a pleasant vehicle climate be achieved efficiently? Researchers found that the potential of energy-efficient air conditioning is all but exhausted. And this applies also to gasoline-powered cars. Inefficiency has its advantages, too: In the past, .
As a strategy to decrease road accidents caused under the influence of alcohol, a group of young students has developed an automotive safety system that detects the alcohol blood level of a potential driver and prevents them from driving..
Vehicle cost, current battery technology, and inadequate consumer knowledge are some of the barriers preventing widespread adoption of plug-in electric vehicles, says a new congressionally mandated report..
Use of clean fuels and updated pollution control measures in the school buses 25 million children ride every day could result in 14 million fewer absences from school a year, based on a new study..
A single oil spill can release 30,000 tons of oil into the ocean if two vessels collide. In grounding the high weight can lead to oil disaster, in the Baltic Sea up to 120,000 tons. This estimate does not include the new giant tankers..
Scientists have built a low-cost centimeter-accurate GPS system that reduces location errors from the size of a large car to the size of a nickel -- a more than 100 times increase in accuracy. The breakthrough is a powerful and sensitive software-defined .
Imagine a battery-powered plane that has 10 engines and can take off like a helicopter and fly efficiently like an aircraft. That is a concept being developed by NASA researchers called Greased Lightning or GL-10..
Ethanol fuel refineries could be releasing much larger amounts of some ozone-forming compounds into the atmosphere than current assessments suggest, a new study finds. Airborne measurements downwind from an ethanol fuel refinery in Decatur, Illinois, show.
If consumers have their way, self-driving cars will enable parents to keep tighter reins on teen motorists. A new survey reveals that people are soundly in favor of putting parental controls in high-tech cars of the future. One thousand people, aged 18 to.
There’s a lot one can learn about the human psyche at a car dealer’s. This is where the allegedly shady dealer meets the self-proclaimed tough bargainer. Researchers analyzed sales talk and help the industry to work more efficiently. They.
