Vehicle-To-Vehicle (V2V) and Vehicle-To-Infrastructure (V2I) communications are going to play a big role in future automobiles when it comes to autonomous vehicles, but in the near term, these technologies are being looked at as a way to make the roadways safer by reducing crashes and congestion. As part of its Safety Pilot program, the U.S. Department of Transportation has announced plans for the largest-ever real-world test of V2V and V2I technologies consisting of almost 3,000 cars, trucks and buses in Ann Arbor, Mich.
V2V and V2I allow vehicles to connect and communicate with one another along with roadways and intersections using a wifi signal with the intention of reducing vehicle collisions in the instances such as rear-end collisions, blind intersections, vehicles running a red light or vehicles changing lanes when another vehicle is in its blind spot. Automakers, including General Motors and Ford Motor Company have already been testing intelligent vehicles, but the benefit of an American government-sponsored program like this is that it could create a universal language for vehicles to communicate with each other rather than each automaker coming up with its system independently.
Both GM and Ford are supplying vehicles for this program, but there will also be extensive feedback received from drivers. Ahead of its real-world tests, the DOT conducted a study that found 90-per cent of drivers who experienced V2V and V2I had a "highly favorable opinion" of the technologies. Safety Pilot will last for a year, and the data collected will help the National Highway Traffic Safety Administration determine how the technology can be used in the future, along with what, if any, laws need to be made regarding V2V and V2I.
GM says that it can start offering this technology in its cars by the end of this decade and Ford says it has already started developing Intelligent Vehicles.

DOT Launches Largest-Ever Road Test of ConnectedNearly 3,000 Vehicles Will Send Wi-Fi-like Signals that Warn of Safety Hazards, Could Help Reduce Crashes During Year-Long Research Project
Vehicle Crash Avoidance Technology

ANN ARBOR, Mich. – Nearly 3,000 cars, trucks and buses equipped with "connected" Wi-Fi technology to enable vehicles and infrastructure to "talk" to each other in real time to help avoid crashes and improve traffic flow will begin traversing Ann Arbor's streets today as part of a year-long safety pilot project by the U.S. Department of Transportation. U.S. Transportation Secretary Ray LaHood joined elected officials and industry and community leaders on the University of Michigan campus to launch the second phase of the Safety Pilot, the largest road test to date of connected vehicle crash avoidance technology.
"Today is a big moment for automotive safety," said Secretary LaHood. "This cutting-edge technology offers real promise for improving both the safety and efficiency of our roads. That is a winning combination for drivers across America."
Conducted by University of Michigan's Transportation Research Institute (UMTRI), the road test, or model deployment, is a first-of-its-kind test of connected vehicle technology in the real world. The test cars, trucks and buses, most of which have been supplied by volunteer participants, are equipped with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication devices that will gather extensive data about system operability and its effectiveness at reducing crashes.
According to DOT's National Highway Traffic Safety Administration (NHTSA), V2V safety technology could help drivers avoid or reduce the severity of four out of five unimpaired vehicle crashes. To accomplish this, the model deployment vehicles will send electronic data messages, receive messages from other equipped vehicles, and translate the data into a warning to the driver during specific hazardous traffic scenarios. Such hazards include an impending collision at a blind intersection, a vehicle changing lanes in another vehicle's blind spot, or a rear collision with a vehicle stopped ahead, among others.
"Vehicle-to-vehicle communication has the potential to be the ultimate game-changer in roadway safety – but we need to understand how to apply the technology in an effective way in the real world," said NHTSA Administrator David Strickland. "NHTSA will use the valuable data from the 'model deployment' as it decides if and when these connected vehicle safety technologies should be incorporated into the fleet."
The model deployment is the second phase of DOT's connected vehicle Safety Pilot, a major research initiative managed by NHTSA and the Research and Innovative Technologies Administration (RITA) Intelligent Transportation Systems Joint Program Office. Earlier this year, DOT released data from a series of "driver acceptance clinics" conducted during the first phase of the Safety Pilot. The study revealed that an overwhelming majority of drivers (9 out of 10) who have experienced V2V technology have a highly favorable opinion of its safety benefits and would like to have V2V safety features on their personal vehicle.
"Many significant advances in roadway safety resulted from the collaborations between government, industry, and academia," said Gregory D. Winfree, RITA Deputy Administrator. "The deployment today is the culmination of years of cooperative research on forward-thinking technology designed to save lives and prevent injuries on America's roads."
The information collected from both phases of the Safety Pilot, and other key research projects, will be used by NHTSA to determine by 2013 whether to proceed with additional activities involving connected vehicle technology, including possible rulemaking.
