Key-Words: - ITS, Smart Grid, Infrastructure, PLC, Sensors Network, Transport Management System 1 Introduction In nowadays the intelligent transport systems is very important to manage and monitor the problems caused by traffic jams, accidents and incidents in the world and the use of information technologies to simulate and make a real-time control permit to minimize these problems. The congestion has been increasing as a result of urbanization and effective changes in population density, so the traffic jams reduce the use of transport infrastructure and increase travel times, air pollution and fuel consumption. The ITS includes several management systems as: traffic light management system, track and trance systems, panel with messages, speed cameras and so on. These management systems needs to communicate with the sensor and actuators networks installed in the city, in order to obtain the real information of each local, so an effective communication system to exchange data between TMS and ITS elements is necessary. For data communication several technologies are available as: pair of wire, dedicated line, radio frequency, mobile and others, but the maintenance and deployment cost often prevents the ITS projects. In this context and considering another monitoring system, called Smart Grid, the paper present an alternative solution to enable the communication for ITS.
