People often explain car crashes by saying they saw what was coming “too late.”  That refrain may become a thing of the past. The University of Michigan’s Transportation Research Institute is set to test the largest vehicle to vehicle (V2V) communication system to date.

V2V communication is a system in which vehicles can send messages to one another.  These messages can range from warnings about changes in speeds on highways or upcoming traffic to an alert that there is a vehicle in one’s blind spot.  V2V communication could be especially useful in situations where the driver has limited visibility because of weather, larger vehicles ahead, or the nature of a road or intersection. This technology has the potential to radically reduce the number of crashes and improve traffic flow.

Over 3,000 volunteers have agreed to participate in the study on 73 miles of roads around Ann Arbor, Michigan. The cars will communicate with one another by sending messages over WiFi and providing GPS coordinates. The roads have been equipped with 29 wireless devices to facilitate the V2V communication.

The V2V test is being funded by a $14.9 million grant by The US Department of Transportation.  Other institutions contributing to the project include Parsons Brinkerhoff, Mixon Hill, HNTB, SAIC, Texas Transportation Institute, AAA of Michigan, ESCRYPT, the Office of the Vice President of Research at the University of Michigan, and the Michigan Economic Development Corporation. The results of the V2V test will be used by USDOT in order to determine whether to require new vehicles to come outfitted with V2V communication devices.
