The street name has a dual function: on the one hand it identifies an area of the municipal territory where, in addition to the area more specifically used for the circulation of vehicles and/or pedestrians, there may be other areas of public land with different facilities. Furthermore, the street toponym corresponds to a portion of the road network to which a given 'name' (e.g. Piazza Saffi) is assigned by a given municipality, an element of the municipal street directory to which the house numbers refer. Toponyms are assigned regardless of patrimonial status of the road. The road network must therefore also be completed with exclusively pedestrian paths either because they have their own toponym and house numbers (for example "Galleria Mazzini" in Forlì) or because they are used for the projection onto the road network of house numbers accessible from internal passages rather than from street in front of building. The same Road Element can contribute to the construction of the layout of more than one toponym in situations where the border between different municipalities stands on the edge of the road itself; vice versa, within a municipality a road element can be aggregated to form a single road toponym. A route characterized by the same name that crosses several localities or hamlets in which the civic numbering is assigned locally to the locality itself must be treated as a "road toponym" distinguished not only by the name of the road but also by the name of the locality/hamlet. In the Regional Topographical Database it is represented only by its layout.
