Regione Toscana - Grafo strada Iter.Net version 4.48

The Tuscany Region is equipped with an information layer of the road network in compliance with the existing standards and directives on the subject at national and European level. The traffic graph consists of the following basic entities:---Road element: linear entity delimited by two junctions, identified by an ordered set of points. It generally represents the axis of a single-track section of road.---Road junction: normally represents a point of intersection of the axes of two road elements. A junction is always a point entity (node), represented in geometric terms by a pair of coordinates.The following are derived from the basic entities:---Administrative extension: set of road elements aggregated according to administrative criteria, ie 'administrative classification of the road and its assets'.---Road name: corresponds to a portion of the mobility network, which is assigned a certain name by a given municipality, a name that is part of the municipal road network.The basic entities have been associated with other information:---Civic number: is used to define an address, has no spatial component and is always logically related to access. Each house always corresponds to an external access that can be direct or indirect.---Access: specific element identifying the main or secondary external, direct or indirect access to a specific place of residence/activity in the territory.
