The ETSI standardized message set for vehicular communication is Cooperative Awareness Messages (CAM). CAM is a set of VANETs application that intended for the intelligent transportation system using the periodically messaging services that can be used to send and receive notification. The traffic congestion is significant factor in disrupting traffic flows. The CAM notifications are utilized to enhance traffic flow by mitigating traffic congestion through Vehicle to Vehicle (V2V) communication System. The using of CAM notification can parse congestion at high traffic density points.
