Traffic Congestion Detection and Management Using VANET

VANET(Networking)

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. But some problems occur during the transmission of messages like Low Energy signals , Delays in Reporting signals ,Signals are Easy to duplicate .Due to this problem result become low delivery ratio ,less throughput and high load so overcome this problem, 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 packet delivery ratio and throughputs.
