Abstract
The development of Information and Communication Technologies (ICT) has now reached some entirely unexpected domains. Many applications in modern cities lead to novelties, resulting in new habits of the citizens of tomorrow’s smart cities. These innovations include Intelligent Transportation Systems (ITS). An important application domain of ITS is undoubtedly represented by the dynamic and optimized management of traffic-lighted road intersections. Although several works have already been presented in the literature over the years, many have not considered the new perspectives regarding the source of data to manage traffic lights, i.e., not only Wireless Sensor Networks (WSNs), but, mainly, the vehicular communications. This paper introduces an innovative approach to dynamically regulating traffic light cycles and phases in an isolated intersection. The suggested method can fit data management from WSNs and vehicular communications through IEEE 802.11p and LTE-V2V, employing various Fuzzy Logic Controllers (FLCs) that manage vehicles turning movements for dynamic controls of both the phase and the green time of traffic lights. The results obtained will allow us to observe that the proposed application is better than the others. Each of the implemented configurations will bring advantages and disadvantages that allow choosing one configuration or another based on specific project requirements.

Many countries are experiencing a rapid increase in the growth rate of their urban areas, caused by people’s migration to cities in search for education, better jobs, and other social and cultural amenities
City infrastructures must continuously adapt to new technological opportunities, to maintain a high quality of life and services for their inhabitants. e increasing interactivity and technological advances gave rise to the new concept of smart city, which identifies a series of areas of development that transform the essence and functionality of the modern cities. ese areas range from smart mobility to the smart economy, intersecting different areas and development themes
Is paper focuses on a particular perspective related to the smart city, i.e., smart mobility, presenting a solution for an automated and effective management of traffic-lighted intersections. is innovative work in the area of dynamic control at road intersections traffic adapts in real-time and dynamically the cycles and phases of the traffic lights without the deployment of sensors along the roadway. e proposed approach manages real-time data through modern technologies for vehicular communication, including Vehicleto-Vehicle (V2V) and Vehicle-to-Everything (V2X), assisted by Fuzzy Logic Controllers (FLCs)
Summary
Many countries are experiencing a rapid increase in the growth rate of their urban areas, caused by people’s migration to cities in search for education, better jobs, and other social and cultural amenities. E proposed approach manages real-time data through modern technologies for vehicular communication, including Vehicleto-Vehicle (V2V) and Vehicle-to-Everything (V2X), assisted by Fuzzy Logic Controllers (FLCs). Is paper focuses on a particular perspective related to the smart city, i.e., smart mobility, presenting a solution for an automated and effective management of traffic-lighted intersections. From this point on, this paper is organized as follows. The performance evaluations of three different network construction hypotheses are analyzed in Section 4 and highlight all the advantages introduced by the adoption of an intelligent traffic light system to the point that any previous design hypothesis is highly obsolete.
