A Citywide Distributed in VANETs-Based Protocol for Managing Traffic

Abstract

he dawn of wireless communications makes the delivery of real time information at hands. This includes Vehicle to Infrastructure (V2I) and the Vehicle to Vehicle (V2V) communications which opened the doors for superior collection and use of information. In this paper, we try to enhance the use of this information to improve future generations of inVANET-based protocols for controlling traffic intersections. Previous work focused on the flow of the vehicles in one intersection. In this work, we will focus on the flow of traffic across number of adjacent traffic intersections in a city equipped with Road Side Units (RSU). The RSUs cooperation by exchanging information collected from vehicles through V2I and distribute among all RDUs using Infrastructure to Infrastructure (I2I). Advanced knowledge of the moving vehicles will lead to better traffic management at intersections and will reduce waiting time.
