The well-known traffic congestion problem in every environment has negative impact on many areas including economy, environment, health and lifestyle. Recently, a number of solutions based on vehicle-to-vehicle communications were proposed for traffic congestion detection and management. Vehicular Ad hoc networks (VANETs) are used to collect and aggregate real-time speed and position information on individual vehicles to optimize signal control at traffic intersections. Vehicular ad hoc network (VANET) is a promising technology to enable the communications among vehicles. We present a strategy to control traffic congestion with the help of Vehicle-to-Vehicle (V2V) and Vehicle to infrastructure (V2I) communication. This is achieved by transmission of messages which alerts the drivers about possible traffic breakdown. The message transmitted will guide the driver so as to take the decision needed to control the traffic congestion. In this paper proposed Greedy Forwarding and Event Driven Safety message to improve delivery ratio and throughputs.

VANET, Broadcast Alert message, High delivery ratio, Less Congestion
