In this paper the project for the Piedmont Regional Traffic Supervisor (SVR) is described. It is developed by 5T company with the aim of traffic monitoring, forecast and control, over all the Piedmont Region. This is not a simple extension of the current Turin Metropolitan Traffic Supervisor, but a radical evolution of the concept in terms of data sources, data types, models realization criteria and traffic assignment algorithms. 5T is developing a new SVR able to evolve all the monitoring functions to the wide regional area extension, assuring, at the same time, a correct matching of all the traffic information at all the interfaces among the various municipalities. The extension and the different typology of the controlled areas require some specific technical choices that will be described in the paper. Besides, the wideness of the controlled area requires also an integration of classic “physical sensor“ with new “virtual sensors” (Floating Car Data – FCD): details about data acquisition, data completion, data fusion and harmonisation will be provided. Finally, a brief description of all the informative services that will be based on the traffic data generated by the SVR system, as well as a short review of some results, is also provided.
