Traffic Congestion Detection and Management Using Vehicular Ad-Hoc Networks (VANETs) In India

India is a nation which has the one of the largest NonLane based road network in the world. Many developed nations today use Intelligent Transportation system (ITS) to solve traffic related problems and provide smooth and safe ride on roads. The road traffic congestions are recurring problem in India. One of the major reasons that lead to traffic congestion is the poor infrastructure and attitude of road users in India. VANETs are widely emerging in many developed countries as a less expensive, distributive and collaborative traffic congestion system. It basically requires some inexpensive devices to be incorporated in vehicles itself and communicate with geostationary satellite to accumulate the data and fetch into the system. It will basically reduce the cost of project as it doesn’t require implementation of expensive loop sensors and high range video processing devices. Data to be disseminated are buffered at the roadside parked vehicle, which continuously provides data dissemination services for the passing by vehicles and Vehicular Ad-Hoc Networks provides a smart solution for traffic density detection and better parking management of traffic over Non-lane based roads of India. Motivated by the fact that there are large amounts of roadside parked vehicles in urban areas, this paper highlights the findings of a parking-based opinion survey conducted at Delhi city in India and proposes a smart solution for parking management and traffic detection through a data dissemination scheme for VANETs in India. Through this review paper, it has been tried to provide an innovative approach as VANETs in solving traffic problems in India that has significantly large amount of public and private vehicles on roads.
