Engineers have developed a system for taking anonymous cell-phone location information and turning it into an illuminated traffic map that identifies congestion in real time.The system takes advantage of the steady stream of positioning cues--untraced signals all cell phones produce, whether in use or not, as they seek towers with the strongest signals. It is the first traffic-solution technology that monitors patterns on rural roads and city streets as easily as on highways.
Results published in the new issue of international journal, Injury Prevention, show that driver distraction causes one in five crashes reported by drivers. Findings from an Australian study on driver distraction found that drivers engage in a distracting activity on average once every six minutes, which frequently results in driving errors and road accidents.
Graduated driver licensing programs reduce, by an average of 11 percent, the incidence of fatal crashes of 16-year-old drivers, according to a study by researchers from the Johns Hopkins Bloomberg School of Public Health’s Center for Injury Research and Policy and the Johns Hopkins School of Medicine. When examining the most comprehensive programs, which include at least five of seven components, the researchers found about a 20 percent reduction in fatal crashes involving 16-year-old drivers. The report was supported primarily by the National Highway Traffic Safety Administration (NHTSA) and in part by the Centers for Disease Control and Prevention.
In a full car, some poor soul is relegated to the middle of the back seat, the least desirable, most uncomfortable, most "un-cool" spot in the vehicle. It also happens to be the safest. University at Buffalo researchers studied all auto crashes involving a fatality in the U.S. between 2000 and 2003 where someone occupied the rear middle-seat.
Georgia Tech researchers have created a new combustor (combustion chamber where fuel is burned to power an engine or gas turbine) designed to burn fuel in a wide range of devices ? with next to no emission of nitrogen oxide (NOx) and carbon monoxide (CO), two of the primary causes of air pollution. The device has a simpler design than existing state-of-the-art combustors and could be manufactured and maintained at a much lower cost, making it more affordable in everything from jet engines and power plants to home water heaters.
A new study from the University of Michigan found that traffic metering systems that incorporate new algorithms for merging could reduce the seriousness of traffic slowdowns that originate near freeway on-ramps.
The prototype of a revolutionary new type of vehicle only one metre wide specially designed for cities has been developed by a team of European scientists. The vehicle combines the safety of a micro-car and the manoeuvrability of a motorbike, while being more fuel-efficient and less polluting than other vehicles. The CLEVER (Compact Low Emission Vehicle for Urban Transport) vehicle is a £1.5 million collaborative project which has involved nine European partners from industry and research, including the University of Bath
This weekend, high school and college students from across the country will rumble across the surface of the moon without ever leaving Earth. Fifty high school and college student teams are putting the finishing touches on designs of their very own lunar vehicles. Teams from the United States and Puerto Rico are competing in NASA's 13th annual Great Moonbuggy Race.
Researchers have discovered that your level of exposure to pollution can vary according to what method of transport you use, with travelling by taxis resulting in the highest levels of exposure and walking one of the least.
Engineers have developed a wind tunnel that is the only one of its kind in the world capable of running quietly at "hypersonic" speeds, helping researchers to design advanced aircraft and missiles. No other wind tunnel runs quietly while conducting experiments in airstreams traveling at Mach 6 – six times the speed of sound, said Steven Schneider, an aerospace engineer and professor in Purdue's School of Aeronautics and Astronautics.
New research from The Children's Hospital of Philadelphia shows that children riding in SUVs have similar injury risks to children who ride in passenger cars. The study, published today in the journal Pediatrics, found that an SUV's increased risk of rolling over during a crash offset the safety benefits associated with larger, heavier-weight vehicles.
I have a dream that one day.
The tsunami effect to move a load. Imagine a tube or a corridor on a large scale, example Lille Paris, on the same level (yes that it is one of the constraints) filled has half of water.
A growing market for biodiesel fuels is heating up interest in canola among Texas producers. Dr. Brent Bean, Texas Cooperative Extension agronomist here, said he quit participating in the National Winter Canola Variety Trials some time back when interest waned. But he's participating once again due to calls from several producers.
