and driving dont mix
For a year, researchers with the Virginia Tech Transportation Institute
observed the actual daily driving habits of 241 drivers in 100 cars.
It was the first such instrumented vehicle study undertaken. While
80 percent of all crashes and 65 percent of all near-crashes involved
the driver looking away from the roadway within three seconds of
the onset of the event, the researchers discovered that the
most dangerous contributing factor leading to crashes was fatigue.
the road to Challenge X with 170-proof
With the 2005 leg of Challenge X: Crossover to Sustainable Mobility
successfully completed, mechanical engineering professor Doug Nelson
and the Virginia Tech Hybrid Electric Vehicle Team (HEVT) are turning
their design for an ethanol-powered SUV into a working vehicle.
Nelson and the students are among 17 university teams selected by
the U.S. Department of Energy and General Motors to compete in the
three-year Challenge X -- challenging engineering students to develop
designs and technology for the next generation of energy-efficient,
low-emissions vehicles. Read more
devices convert water to hydrogen gas
Wonder where the fuel will come from for tomorrow's hydrogen-powered
vehicles? In a process sometimes called "artificial photosynthesis,"
Virginia Tech researchers are developing catalysts that will convert
water to hydrogen gas. Read more
used to study West Nile virus in Virginia
The spread of West Nile
virus across the United States since 1999 illustrates the potential
for mosquito-borne diseases to expand their range into the US and
have a significant effect on the population. Virginia Tech assistant
professor of geography Korine
Kolivras is using her experience in analyzing the 2001-2002
dengue fever outbreak in Hawaii to understand the potential spread
of West Nile in Virginia. Through the use of Geographic Information
Systems (GIs), she delineated areas in Hawaii that provided a habitat
for mosquitoes and had the potential for outbreaks of mosquito-borne
diseases based on temperature, precipitation, land cover, topography,
and the presence of populated areas. She is developing a similar
risk map for outbreak prevention and control for Virginia.

To make sure ABC's "Extreme Makeover: Home Edition" construction
in Blacksburg, Va., was as safe as it was fast, Virginia Tech's
Center for Innovation in Construction Safety and Health developed
the Rapid Universal Safety and Health (RUSH) system and 50 faculty
members and students served on the "Extreme Safety Corps."

A Virginia Tech team has identified five factors that influence
girls' information technology (IT) career choices -- including race,
parental support, age when introduced to computers, and positive
image of IT. A DVD and guide are available for parents, counselors,
teachers, and academic advisors. Read

radios overcome incompatibilities
After a disaster, like hurricane Katrina,
emergency-responders from many jurisdictions converge. But the radio
systems used by the different jurisdictions are rarely compatible.
Cognitive radio offers a solution. A cognitive radio will configure
itself to talk to any other unit that the responder selects. Read
