Vehicle Infrastructure Integration.

Several years ago I attended a conference in Detroit where this VII initiative was discussed.

At the time it was a concept and a proposal by the automotive industry and transportation technology companies. The VII system uses radio and GPS systems to allow vehicles to communicate with each other as well as to a central operations center. This information can be on upcoming breakdowns, emergency crews, as well as oncoming vehicles. If the road is slippery ahead, a car ahead can communicate that information to your vehicle. The information gleaned from VII systems could also help improve congestion by giving traffic management systems such as is operated by Mass Highway and the Mass Turnpike much better and faster information.
