Cars as traffic sensors

See original story at MIT News -- Cars as traffic sensors

A great example of how ubiquitous networked processors can function together as a single sensor network.
"Data about road and traffic conditions can come from radio stations’ helicopters, the Department of Transportation’s roadside sensors, or even, these days, updates from ordinary people with cell phones. But all of these approaches have limitations: Helicopters are costly to deploy and can observe only so many roads at once, and it could take a while for the effects of congestion to spread far enough that a road sensor will detect them."
"MIT’s CarTel project is investigating how cars themselves could be used as ubiquitous, highly reliable mobile sensors."
