Development of road infrastructure in accordance with the latest trends implies an exchange of information on the wireless interface not only between the cars, but also with the objects of the transport network such as traffic lights and signs. Weather conditions, warnings about traffic jams and accidents.
The American authorities for Highway Safety (NHTSA) call rather to develop a national standard for the exchange of information between vehicles (V2V), because its implementation would annually save more than 1,000 lives a year, and then only through the introduction of care when turning left and Directions crossroads. Cars could receive warning of the approach of oncoming vehicles or other kind of interference occurs, reducing the probability of making a wrong decision by the driver.
System data type V2V could also publicize the possibility of collision with moving in the same direction of the vehicle (currently available solutions are based on radar readings), to warn about the presence of vehicles in the blind spot (now also used for this purpose radars), announce banning traffic light or the approach to the stop line. In addition, systems such as V2V able to do road traffic more evenly, and will reduce average fuel consumption.
Estimated standard for V2V systems should be based on WiFi 802.11p with a frequency range from 5.85 GHz to 5.925 GHz. It is important that vehicles of different brands can communicate with each other. Gather information on specific vehicles and their owners the standard does not provide. In addition, it is proposed to develop protocols to protect this information.
Interestingly, some market participants see in automatically controlled vehicles indirect threat to humanity. For example, the head of the three-dimensional printing systems manufacturer Makerbot in an interview to Fortune admitted that the reduction of accidents on the roads with the proliferation of cars with autopilot will cause a further reduction in the amount available for organ transplantation. In the United States since 1994, traffic accidents provide up to 16% of the total volume of donor organs, and to replace this source professionals will learn how to grow or print .
