How few cell phones are needed to track traffic?
“Results suggest that a 2-3% penetration of cell phones in the driver population is enough to provide accurate measurements of

That’s just one conclusion of a study titled Evaluation of Traffic Data Obtained via GPS-enabled Mobile Phones: the Mobile Century field experiment (pdf) from UC Berkeley’s Institute for Transportation Studies.
