The technology could alert the motorist to upcoming hazards -- such as construction, emergency vehicles, traffic jams or accidents -- before the driver can see them.
In Ann Arbor, Mich., a research coalition lead by the University of Michigan’s Transportation Research Institute equipped nearly 3,000 vehicles with transponders that broadcast the vehicle’s location to other cars and trucks.
The National Highway Traffic Safety Administration has endorsed the technology and is considering proposals to encourage its use.
