Intelligent Traffic System for VANET: A Survey

During the last decades, the total number of vehicles around the world growing enormously. Therefore the focus of manufactures, researchers and government is shifting towards improving the on road safety rather than improving the quality of the roads. The vast development in the wireless technologies emerged a new type of networks, such as Vehicular Ad Hoc Networks (VANETs), which provides communication between vehicles themselves and between vehicles and infrastructure. Various new concepts such as smart cities and living labs [1] are introduced in the recent years where Vehicular Ad Hoc Networks (VANETs) plays an important role. A review of various Intelligent Traffic Systems (ITS) available and various routing protocols with respect to our proposed scheme is done in this paper. This paper also introduces a new scheme consist of a smart city framework that transmit information about traffic conditions that will help the driver to take proper decisions. Our proposed scheme consist of a warning message module composed of Intelligent Traffic Lights (ITLs) which provides information to the driver about current traffic conditions.
