PDIPR Route

Attention new feed URL carto.ain.fr becomes geodata.ain.fr Last modification of graph nov 2023: decommissioning of the RD979 from boulevard Charles de Gaulle to the Alagnier roundabout (urban part in the township) avenue Amédée Mercier Roads are all represented by a single axis even in the case of separate carriageways. At the junctions / intersections, the sections not participating in the main road are cut off at the outer edge of the junction (stop / yield the passage). To ensure the topology of the road graph pseudo route have been added (category _admin=intersection) but does not participate in the linear of the RD. For roundabouts, the calculation of the PR+abs follows the axis of the roundabout in the direction of the route (PR sense) and thus travels part of the roundabout ring virtually while physically there is a discontinuity (PV_beginning / PV_fin). The field '_admin category' allows to know its use. rd / intersection / junction _pn / roundabout. The total length of the network joining as the sum of the cumulf-cumuld of the rd and giratory. Rule for determining the field: axis the wording of the road is in the form Dxx (e.g. D23) For routes with name extensions (letter after the RD number), this extension is added next with a minus (drawn from 6) as a separator (e.g.: D23-C). For roundabouts an extension 'GIRxxx' is added afterwards with an underscore (draw of 8) as a separator. ex D72-A_GIR_02_0262.
