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 mobility 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 Vittorio Emmanuele II" in Milan) or because they are subject to the projection onto the road network of house numbers accessible from internal passages rather than from road on front of building. The same Road Element can contribute to the construction of the layout of more than one toponym in situations in which 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.
