An approach to avoid traffic congestion using VANET

Roads' overload remains a major challenge although they are constantly expanded in order to increase their capacity and improve their efficiency. This tends to cause many problems: environmentally, economically and socially. The advancement of urban traffic management systems, construction and expansion of roads are solutions to address this problem and improve the performance of the road circulation, but these solutions are very expensive and also require more space for the development and permanent maintenance. An alternative would be to use the new technologies in the field of communication for sending traffic information such as treacherous road conditions and accident sites by communicating, for a more efficient use of existing infrastructure. In this paper, we present a new approach based on VANETs, which can help drivers have a better trip, by finding the optimal path to reduce travel time and fuel consumption. This approach aims to avoid congestion and queues in a more efficient and optimal use of existing road infrastructure by analyzing the useful and reliable traffic information collected in real time.
