IVC (Inter-Vehicle Communication) is a promising technology for the The proposed service employs a distributed algorithm to build an approximate congestion perimeter. This task is carried out by dissemination of positioning data of vehicles vertices of a polygon that is a close approximation of the congestion area. Given the polygon and its current location, a vehicle can then plan its escape-way route from the traffic jam.
