Using Cell Phones as Traffic Sensors

UC Berkeley and Nokia researchers used GPS-enabled cell phones to test a technology that could soon transform the way drivers navigate through traffic. Detractors, of course, are concerned about the privacy issues that arise from using GPS technology in cell phones in a pervasive manner. Check out the video below to learn how GPS in mobile phones could replace stationary sensors to predict and monitor traffic flows through urban centers, minimizing the costs currently associated with sensor infrastructure.
