This is Science Today. A team of scientists at the University of California , Berkeley are working on using wireless networking technology, or Wi-Fi, and GPS technology to warn drivers about possible accidents. Engineering professor Raja Sengupta says these types of systems could alert and protect drivers from crashes before they happen.
When people realized that stuff like vehicle defects, stuff like that had pretty much disappeared and crashes mainly happen because of driver error, people got interested in this whole genre of systems called advanced vehicle safety systems, where the idea was to have information systems in your car that would track the motions of neighboring cars and figure out if you were in any danger from any of these neighboring cars.
Sengupta says this technology is the next big step in improving safety on the roads.
Safety is something that has been an overriding concern through much of our automotive history. And this country's record on improving the safety of road travel is extraordinarily good. And people have realized that the next frontier in safety is this kind of information technology.
