Article Introduction
Traffic-jam has always been a big obstacle and pain in the neck as far as reaching a place on time has been concerned but with now gm`s new promising v2v communication the day of overcoming the unthinkable barrier is not too far

Article Description
Imagine you are stuck in the traffic jam for no reason due to some accident. Sounds irritating, isn`t it? But these are the situations where one feels helpless and hopes there would have been some kind of help--a help in form of warning system, which could have informed about the accident to cars in the range of 100 meters after the any accident has occurred.

In order to improve driving safety, traffic organization and easy hotspot connections, General Motors Corp. (GM) has developed vehicle-to-vehicle (V2V) communication technology. This technology enables a vehicle to detect the position and movement of other vehicles up to a quarter-mile away.

In case of any problem, the technology uses a computer chip and GPS (Global Positioning System) technology to identify the magnitude of problem-- whether it is in blind spot, or an accident-met car stopped ahead on the highway but hidden from view, its all there in its purview.

The technology gives warning to the drivers with chimes, visual icons and seat vibration, thus, ensures vehicles to anticipate and react to changing driving situations. If the driver doesn`t respond to the alerts, the car can bring itself to a safe stop, avoiding a collision, claims GM.

The V2V communication is so effective that it can alert the driver to vehicles in blind spots with a steady amber light in the side mirror. In case of activation of turn signal, a flashing amber light and gentle seat vibration on the side notifies the driver.

According to GM, Pile-ups on congested roads during rush hour due to a chain reaction rear-end collisions could be reduced. Using V2V, the vehicle monitors messages from other vehicles up to a quarter of a mile ahead. The trailing vehicle indicates by a warning signal to the driver with visual icons and seat vibrations on the front and then automatically brakes if there is danger of a rear-end collision with the vehicle ahead.

Also, GM said its V2V technology could warn the driver when vehicles ahead, regardless of lane, are stopped or traveling much slower or any vehicle ahead brakes hard, allowing the driver to brake or change lanes as needed. It also can use rear lights to warn the other driver when the approaching vehicle is moving very quickly and a rear-end collision is imminent.

Although other vehicle manufacturers are working and developing similar technology, GM`s unique advantage is in its ability to leverage or enhance existing systems such as OnStar and StabiliTrak systems to deliver this solution more quickly and cost effectively.

"V2V technology gives drivers a sixth sense to know what`s going on around them to help avoid accidents and improve traffic flow," said Larry Burns, GM vice president of research & development and planning.
