Priority based Algorithm for Traffic Intersections Streaming Using VANET

Intersections play an important role in traffic management. Traditional inte rsecti on management systems do not offer an optimal solution. Vehicular Ad-Hoc Networks (VANETs) offer communications among vehicles which allow the implementation of intelligent intersection management. Num erous techniques have been proposed in the li terature to regulate traffic at intersection intelligently. However, these research works do not provide a general solution based on user-defined priorities and vehicles density. In this paper, we propose a nove 1 priority based algorithm to man age intersection traffic us ing vehicle-to-vehicle communication and coalitions are formed among vehicles based on their priority. Our algorithm, let the vehicl es with higher priority pass the intersection before the lower priority vehicles. Simulation results showed that our algorithm improved throughput by 21.6% and travel time by 40.24% when compared with the traditional-based algorithm.
