The National Highway Traffic Safety Administration, the authority in loads of American highways has just published its report on the State of the current art V2V, i.e. the exchange of data between vehicle communication. The implementation of communications in the whole of the American fleet units could prevent up to 592,000 accidents per year on American roads, either 1.083 lives saved per year, 270,000 wounded and 728.000 accidental damage. Still many problems to solve, whether at the level of frequencies to give to these communicating cars, to the certification of such equipment, their cyber security, or to the legal implications of such a device.
Connecting cars to prevent accidents
3 o’clock in the morning on a U.S. Highway. A heavy driver loses control and the trailer extends across three lanes. Inevitably, the cars that follow will fit into the truck. It will be nothing, all motorists receive an alert on their dashboard and stop before embedding itself in the trailer. Communication V2V (for Vehicle to Vehicle) boxes have sent information from the car accident car, to avoid any collision. This scenario is not theoretical for vehicles fitted with these enclosures in tests in the United States. By 2020, all light vehicles could be equipped with such equipment.
Since the end of the 1990s, the U.S. Transportation Department are working on the equipment to avoid accidents and prevent collisions. It is between August 2011 and January 2012 things accelerated: a test is conducted 100 drivers to validate the acceptance of such systems by the public. Then a first deployment is conducted in Ann Arbor, Michigan. 2,800 vehicles are then fitted and 75 miles of road infrastructure (this is called the V2I for vehicle to Infrastructure). Today, the Department is investigating a large deployment of the system.
Price of an equipemement : $ 350
According to the NHTSA estimates, the cost of such equipment should be in the order of $341 to 350 in 2020, a price that could descend to $209 to 227 to 2058. The study considers even that the additional weight will result in increased fuel consumption in the order of $9 to 18 per year. The annual cost to the United States will be between 300 million to $ 2.1 billion per year, depending on the implementation that will be chosen.
The report highlights the many obstacles which still remain to be overcome before launching this deployment. Technical problems, of course, with procedures to put in place to test and certify equipment, radio frequency he’ll have attributed to cars. We must also address the problems of protection of personal data and especially Security. This adjoining car must be protected from hacking and interference of any kind that it will necessarily subject one day or the other. Finally, the American legislator will have to lean on its cradle: who will be responsible in case of road accident? The driver? The automaker which has installed the housing in the vehicle? The installer who designed it? The adjoining infrastructure?
