2018 AVERAGE DAILY TRAFFIC ON BDTRE ROAD ELEMENT

Additional attributes to the linear component of the BDTRE traffic graph, relating to the Average Daily Traffic (TGM) on an annual basis and to other information related to vehicular mobility, derived from the comparison with the Regional Supervisory Graph (SVR) managed by 5T srl on behalf of the Region Piedmont. For further details on the production methods of the TGM data associated with the SVR Graph, consult the file (Modello_SVR.pdf) contained in the material being downloaded. 2018 Update, annual frequency.

lineage Data production method: in the SVR Graph (Regional Supervisor graph) the information is distinguished by direction of travel. The BDTRE graph does not provide for this distinction so that the SVR data before being attributed to the elements of the BDTRE graph are aggregated (summed or averaged as appropriate). The tracing of the two graphs does not exactly coincide as they come from different sources so that the transfer of information takes place through the transformation of the SRV graph into points at a regular distance (1 metre) and their association to the arcs of the BDTRE graph based on the criterion of nearness. For each set of points associated with a single BDTRE arc, the mode of the values ​​of the attribute to be transferred is statistically calculated, which represents the value of the data made available. Furthermore, the SVR Graph represents a subset of the complete Piedmont road network. Therefore, on the BDTRE graph, only the arcs corresponding to the subnetwork represented in the SVR graph are valued with the TGM.
