GPS units in the driver’s seat

Traffic project uses computers, wireless data to avoid gridlock

Picking up doughnuts on the way to work recently, George List slid back into the driver’s seat and heard a voice from the cup holder suggest an alternate route.

The car wasn’t talking, exactly. The voice came from a handheld computer nestled in the holder that links his car to 200 other vehicles in the area. Data from all the vehicles – where they are, how quickly they move – are being used to create snapshots of area traffic patterns. The system had detected a bottleneck ahead and quickly calculated a faster route.
