New GPS Navigator shows Traffic Jams Ahead

Hugh Pickens writes: "The New York Times is running an article on Dash Express, a new navigation system for automobiles that not only receives GPS location data, but broadcasts information about its travels back to Dash over a cellular data network where it is shared with other users to let them know if there are slowdowns or traffic jams on the road ahead and propose an alternate route. The real benefit of the system isn't apparent until enough units are collecting data so Dash distributed over 2,000 prototype units to test drivers in 25 large cities. The continuous two-way reporting lets the system measure how fast traffic travels on a given road, and use that information to compile a highly detailed and accurate database of traffic information so Dash units can warn each other through the network the second they hit a traffic slowdown."
