Monitoring traffic flows on road infrastructures is an increasingly common practice: different types of sensors and devices for counting and classifying vehicles have been tested and installed on the European roads in the last years, contributing to the growing of the availability of several databases. On the other hand, methodologies for the assessment, in the transport field, of the energy consumption and the consequent emissions require several data sets, which are not always available. Consequently, it is interesting to investigate an approach able to model the energy dissipation, starting from simple mechanical rules and traffic monitoring data, with related parameters. The presence of ITS may, as well-known, have a positive influence on traffic flows. Starting from this assumption, the paper presents different scenarios based on actual and simulated data, in order to estimate the energy used by a vehicular flow, and its changes when such flow is influenced by an ITS . As concerns the approach presented in this paper, it takes into account both a mechanical model, which provides an easy evaluation of energy consumption, and a traffic micro-simulation approach, starting in both cases from the measurement of the classical traffic flow parameters.
