Vehicular Ad hoc NETwork (VANET) is developing technology in vehicular environment. It is sub group of Mobile Ad hoc NETwork (MANET). VANET is a technology that uses moving vehicles as nodes in network to create mobile network. In this paper, the authors present the concept of adaptive beacon broadcast and adaptive congestion control for safety critical message in VANET. When large number of vehicles transmits beacons at a higher frequency then bandwidth can be exhausted very easily, so number of packet collision occurs.
