Tele Atlas, that company that creates mapping databases for many GPS devices, has teamed up with software startup Inrix, and the result is new trafficking software that uses billions of pieces of historical traffic data to predict how congested roads will be throughout the day.

You’ll be able to use this software algorithm along with your GPS navigation system to receive accurate estimates of traffic flow, without paying for live traffic updates. What if there’s an accident? There is one way to make this system even more accurate.
