Vehicle-to-vehicle communications is a promising technique for driver support systems to increase traï¬ƒc safety and eï¬ƒciency. A proposed system is the Congestion Assistant , which aims at supporting drivers when approaching and driving in a traï¬ƒc jam. Studies have shown great potential for the Congestion Assistant to reduce the impact of congestion, even at low penetration. However, these studies assumed complete and instantaneous availability of information regarding position and velocity of vehicles ahead. In this paper, we introduce a system where vehicles collaboratively build a so-called Traï¬ƒcMap, providing over-the-horizon awareness. The idea is that this Traï¬ƒcMap provides highly compressed information that is both essential and suï¬ƒcient for the Congestion Assistant to operate. Moreover, this Trafï¿½?cMap can be built in a distributed way, where only a limited subset of the vehicles have to alter it and/or forward it in the upstream direction. Initial simulation experiments show that our proposed system provides vehicles with a highly compressed view of the traï¬ƒc ahead with only limited communication.
