Traffic jam ahead warning
This function enhances the safety of vehicles which approach a traffic jam or build the tail end of a traffic jam. The function aims at avoiding (fatal) rear end collisions which are often caused by traffic jams on highways. With help of C2C- or C2I-communication, vehicle systems are able to warn the driver even before the traffic jam could be noticed by the driver himself. Thus, the driver is informed in time and can react smoothly and safe.
