reduce traffic congestion. CarTel is a distributed, GPS-enabled
mobile sensor network that uses WiFi "opportunistically" to exploit
brief windows of coverage to update a central traffic analysis
"The CarTel system is used to test a growing number of
automotive-related research projects at MIT's Computer Science and
Artificial Intelligence Laboratory (CSAIL)..."
