Researchers are trying to develop a transportation system where vehicles communicate directly with each other, giving drivers warnings about en route traffic.
The concept will allow a single driver to control multiple vehicles or routing vehicles around hazardous road conditions.
A model has been developed to improve the clarity of the vehicle-to-vehicle (V2V) transmissions needed to make that concept a reality.
"The model helps us understand how the V2V signals are distorted," Dr. Dan Stancil, head of North Carolina State University's Department of Electrical and Computer Engineering and co-author of a paper on the work, said.
"While there are smartphone apps that can tell you about traffic jams, there is a time lag between when the traffic jam begins and when the driver is notified."
"One advantage of this sort of direct communication between vehicles is that it has very little time delay, and could warn you to apply the brakes in response to an event only hundreds of yards away," he said.
V2V communication relies on transmitting data via radio frequencies in a specific band.
The study is published online in IEEE Journal on Selected Areas in Communication.
