A Traffic Management Service Based on V2I Communication for Vehicular Ad-hoc Networks

Abstract

In the last years, the vehicle flow increases faster than road infrastructure in urban areas. In this scenario, traffic related problems are increasing and affecting people day life, including travel time and health problems. Considering the literature works, there are a number of solutions to deal with traffic congestion, however, they relay on central server or totally distributed. This work proposes a solution for traffic management based on the V2I communication, i.e., communication between vehicles and Road Side Unit. During their trip, vehicles send messages to the closest RSU and when they face a traffic jam, vehicles request information to the closest RSU regarding information of streets (travel time). Using this information, each vehicle is able to find alternatives routes. We compare our solution to a literature one. Simulation results showed that the proposes solution is able to decrease the travel time with a low impact on travel distance.
