Traffic and technology: collective navigational driving

Here's an interesting New York Times article on a technological device that can help drivers: Navigating With Feedback From Fellow Drivers (By Roy Furchgott - Published: October 18, 2007)

Dash Navigation's Dash Express "not only receives location data from the satellites of the Global Positioning System, like other navigation units, but it also broadcasts information about its travels back to the Dash network."

In other words, this device offers GPS-and-other-driver-assisted driving. By collecting data from other devices on the road, the system can alert you to what's up ahead. It won't work well, though, until there are enough units out there on the road.

Cool idea--if it works... Anything that can improve traffic is welcome on this blog...
