"Hallitubes" - high-speed transit system with terrorist-resistant features proposed.
SAN DIEGO, Calif. A grassroots anti-congestion initiative headed by Attorney Greg Maizlish advocates rider-agility-based electric vehicle commuting through thin, low-elevated tubes. Twenty other referendum measures combat road delays with new technologies as part of a California Proposition plan.
a body through it w.o. overheating, and without the friction being too strong for the rider to hold on ? This scheme is advocated, with images, at http://www.generaltransit.com (check INOVETA) toward middle of page. Based on futurama tubes I guess..
A new article publishing in the latest issue of Review of Policy Research examines the evolution and devolution of speed limit laws and their effects on fatality rates. The author did not find a significant increase in fatalities per miles driven after speed limit laws ceased to be national and states could, and some did, increase their highway limit to more than fifty-five miles per hour. "Automobile safety features and enforcement emerge as important factors in increasing highway safety; speed limits are far less important," author Robert O. Yowell explains.
Senior citizens not only drive more these days, but have sped past teenagers as the age group with the highest number of traffic accidents per mile. These and other sobering statistics highlight the need for changes in state driver's license renewals to address the risks that elderly drivers pose to other drivers and themselves, David Rosenfield writes in the current issue of the Elder Law Journal, published by the College of Law at the University of Illinois at Urbana-Champaign.
A new study by a national governors association has found that of the 50 jurisdictions surveyed, 42 indicated there exists a “cushion” of 5-10 mph, not only in the minds of the public but also in enforcement practice. “This cushion truly exists across this country and in some cases is more than 10 mph above posted limits."
The National Highway Traffic Safety Administration (NHTSA) estimates that airbags installed in automobiles have saved some 10,000 lives as of January 2004. A just-released study by a statistician at the University of Georgia, however, casts doubt on that assertion. In fact, said UGA statistics professor Mary C. Meyer, a new analysis of existing data indicates that, controlling for other factors, airbags are actually associated with slightly increased probability of death in accidents.
Researchers conclude in an article to be published in June that it could take "several decades" to overcome daunting technical challenges standing in the way of the mass production and use of hydrogen fuel cell cars. The article notes that "success is not certain" in efforts to develop inexpensive, hydrogen-powered fuel cells and to create the vast storage and transportation infrastructure needed for the vehicles, stressing that hydrogen's "wide-scale use is laden with potential technical, economic and societal impasses."
Red-light cameras can reduce the number of injuries from car crashes at intersections by up to 30 percent, according to a new worldwide review of studies. Publication of the systematic evidence review comes as many localities are installing the cameras over the objection of opponents who contend they are merely municipal revenue-raising devices that invade motorists’ privacy.
Over the last several years many new alloys have been developed to offer increased fitness for purpose, increased service life, and reduced weight. On the transportation side in the ferrous group are the Martensitic, Dual Phase, and strip steels. Their increased strength and reduced weight help to meet CAFE legislation by increasing gas mileage etc. I can see increased use of these type of steels in military vehicles, heavy equipment, building supports, etc.
BBA fulltime Program in Switzerland.
I am doing BBA Full time Program from B.M.University in Switzerland. It is a full-time program for 3 years. It is conceived to distribute to the students an understanding of the concepts and practices in Management. The Bachelor of Business Administration is designed to provide a strong practical undergraduate level education using the principles, theories, and tools necessary to succeed in business. The BBA coursework is designed to train not only proficient, highly skilled professionals who are both comfortable and capable in an environment of rapid change, but also to demonstrate leadership, the understanding of human relationships, and problem-solving abilities essential for success in any business endeavor.
Children on school buses collectively inhale as much or more exhaust emitted from those buses as does the rest of the city's population, according to a new analysis by researchers at the University of California. The results highlight the problem of "self-pollution," or exhaust from the vehicle leaking into the cabin, particularly among older buses. This also is the first study to specifically look at how much exhaust is breathed in on school buses.
A small autonomous underwater vehicle, or AUV, named Spray was launched yesterday about 12 miles southeast of Bermuda. The two-meter-(6-foot)-long orange glider with a four-foot wingspan will slowly make its way northwest, crossing the Gulf Stream and reaching the continental shelf on the other side before turning around and heading back to Bermuda, where it will be recovered in July.
PlayStation users worldwide can now see for themselves what happens when Ariane launcher technology is applied to Le Mans racing. All they have to do is sit back and select which Pescarolo racing car they want to test-drive. Gran Turismo 4, a new PlayStation 2 game, features the two custom-built top-performance Pescarolo racing cars that took part in the Le Mans endurance race in 2003 and 2004. Both were constructed using technologies developed for European space programmes.
Automobile rollovers often occur when a car's wheels lose traction, the vehicle slides sideways, and the lateral force causes the car to flip. Of course, the tires "know" they're skidding long before the driver can react by turning the wheel. But what if the wheels were smart enough to alert the vehicle's control and stability systems to compensate for the loss of traction with an appropriate power boost? That's just one future application of the tiny, wireless strain sensors that UC Berkeley engineers are developing in the Microfabrication Laboratory. Someday, the sensors could be bonded to most any steel structure -- from an automobile suspension to a critical girder in a building -- to keep a constant vigil on the forces that affect a structure's performance.
If you have been stuck in traffic behind a motorist yakking on a cellular phone, a new University of Utah study will sound familiar: When young motorists talk on cell phones, they drive like elderly people, moving and reacting more slowly and increasing their risk of accidents.
