VAIMA: A V2V based intersection traffic management algorithm

The evolution of the standard 802.11p and the appearance of connected vehicles and vehicular communications have arisen as the solutions in the vehicular safety and traffic management. The correct management of intersections is one of the key issues to assure a fluid traffic flow and to avoid vehicles collisions. Cooperative Awareness Systems based on vehicular communications can address the management of intersections. This work proposes a management algorithm, VAIMA algorithm, which considers Vehicle-To-Vehicle (V2V) communications and information provided by each vehicle about their intention. VAIMA is compared with a state-of-the-art mechanism, VVTLA [1], showing performance gains between 11% and 26% in terms of waiting time reduction along with a better fairness behavior.
