2800 cars with WiFi will try not to collide with each other

Engineers from the University of Michigan Institute for Transportation Studies, in conjunction with the US Department of Transportation, have begun preparing a large-scale Safety Pilot road safety experiment. In a few weeks, about 2,800 cars and trucks and buses will begin to “communicate” wirelessly in Ann Arbor, Michigan. The vehicle-to-vehicle (V2V) system with millions of connections between nodes is deployed there - real car Internet.

In a wireless network, cars in real time will be able to inform each other about the speed and direction of movement, receive information from traffic lights and road signs. First of all, it is necessary to prevent collisions - in case of danger the system will give a signal about the need to slow down. In the future, such a network will become necessary for the normal functioning of unmanned vehicles. After all, it is much easier for them to receive information via the network, rather than by pattern recognition.

Automobile Internet will help to eliminate accidents, and at the same time improve the distribution of traffic flows on different roads from the calculation of minimizing the cumulative travel time for all road users.

Synchronizing actions with each other, unmanned vehicles can keep a much smaller distance between them - this also allows you to unload the tracks and reduce traffic jams. Traffic lights will turn on green when the car approaches, if there is no one else at the intersection.

Last year, more than 32,000 people died on US roads. According to the calculations of specialists, the number of victims can be reduced by 80% if you implement such wireless communication systems.

Cars for the Safety Pilot experiment were provided by all the major automakers - Ford, General Motors, Honda, Hyundai / Kia, Mercedes-Benz, Nissan, Toyota and Volkswagen / Audi.
