The University of Baltimore has developed a system that will track large clusters of cell phone users and map them against road grids. The system can tell the difference between pedestrians and moving cars. It can give transportation agencies a constantly updated picture of traffic flow across thousands of miles of highways allowing them to divert drivers by issues alerts by radio or on electronic road signs.
"The potential is incredible," said Phil Tarnoff, director of the Center for Advanced Transportation Technology at the University of Maryland. He said the monitoring technology could possibly help reduce congestion in some areas by 50 percent.
The opportunities for cell phone data mashups are endless. This is a great start – I hate sitting in traffic.
