I2V and V2V communication based VANET to optimize fuel consumption at traffic signals

Traffic signals have become an invaluable tool in ensuring smooth flow of motor vehicles at intersections. But where we gain in terms of orderly flow of traffic, we lose out in fuel wastage and pollution. This is because people often leave the engine of their vehicle running while waiting at signals. In this paper, we propose a system that targets this problem. By creating a channel of communication between the traffic signal and the vehicle, we can ensure that the engine is shut off automatically. Various parameters are taken into consideration during the controlling of the engine start-stop action. When these parameters are found to be within a given set of conditions, the engine is shut off. If any one of these parameters changes, the engine is turned on automatically, saving the driver the hassle of turning the engine on manually.
