The objective of this paper is to present a preliminary study of the inter-vehicle communication advent. In the beginning the text shows a short introduction about inter-vehicle communication, where it may be applied and which are the benefits that it could bring to local traffic. Then it is presented a survey with the main technologies used in vehicle-to-vehicle and vehicle-to-infrastructure communication, as well as their requirements. Following, it is proposed a model of a specific application for vehicular networks involving traffic lights.In this model vehicles and traffic lights communicate with each other in order to perform faster and more efficient approaching and starting. The both cases were simulated by software in order to study the dynamics of the moving vehicles and this paper presents their results and analysis. At the end are final considerations about the work and suggestions for future efforts.
