New software will tell you if there is a problem on your route and what you can do to avoid it, it will even give you an audio alert. It works using signals from GPS devices on phones that are in traffic. UC Berkeley and Nokia official said that your privacy will be protected:
"We collect as little information as possible and we get rid of privacy invasive information every step of the way. So that means your phone never sends information that reveals who you are. We strip away all the billing information, and all of the personally identifiable information," said Dan Work, U.C. Berkeley graduate student.
They just need to know where you are at that time; they don't even want to know where you came from or where you are going. They do think they will be able to get you information about a traffic problem quicker then the radio, or even the CHP.
