According to the national highway traffic safety administration estimation, 24,050 people were killed in road accidents between January to September 2011. The number of injured and losing limbs are higher. Now, our car manufacturers have invented a technology which can avoid these accidents and can save lifes called V2V and V2I.
What is V2V and V2I
V2V(Vehicle to Vehicle) and V2I(Vehicle to Infrastructure) is a new emerging concept. It can enable our vehicles to communicate with each other and also with the things around it, even the road. By communicating with the other vehicles and other objects around, the car can alert the driver about the danger. It can calculate the distance between your car and other car. As the car will approach very close to the another one, it will alert the driver and can also stop the car automatically. The object is in research in nowadays.
How V2V and V2I works
V2V and V2I communicate with wireless technology. It uses network protocols to communicate. A sensor device is installed in the vehicles and infrastructure(road, building etc). It uses Dedicated Short Range Communication(DSRC) devices. DSRC works in 5.9 GHz band with bandwidth of 75 MHz and approximate range of 1000m. Sensor device gather the information about traffice, weather and nearby devices. It gives alert signal to the driver when vehicle tends to collide somewhere and gives driver enough time to react and avoid the accident.
V2V enabled Cars
General Motors are active in development of V2V technology. They demonstrated the system in 2006 using Cadillac vehicles. Other automakers are also working on V2V include BMW, Honda, Audi and Volvo.
