A Hybrid V2I and V2V Approach for Urban Traffic Management in Vehicular Networks

This work presents DESTINy, a traffic management solution for vehicular network using V2V ad V2I communication. Considering a number of RoadSide Units (RSUs) deployed in the road infrastructure, DESTINy divides the city map into regions and each RSU is responsible to store information about traffic conditions of its responsible roads. When necessary, each vehicle requests information to the closest RSU and using the travel time information of the roads inside the region where the vehicle is, it calculates alternative routes with lower travel time. When forwarding the response message, the vehicles also update their local database in order to reduce the number of transmitted messages. Our solution was evaluated considering different literature solutions and presents better results considering network and traffic metrics, providing a reduction of number of message of approximately 70 % as well as, a reduction in the average travel time about 26%.
