Description

Attention new flow URL carto.ain.fr becomes geodata.ain.fr Last modification of the graph Nov 2023: decommissioning of the RD979 from Boulevard Charles de Gaulle to the roundabout of the Alagnier (urban part in the town of bourg) avenue Amédée Mercier Roads are all represented by a single axis even in the case of separate pavements. At junctions / intersections, sections not participating in the main road are cut off at the outer edge of the junction (stop / cede the passage). To ensure the topology of the road graph pseudo roads have been added (categorie_admin=intersection) but do 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 (meaning of the PR) and thus travels part of the roundabout virtually while physically there is a discontinuity (PV_beginning / PV_end). The field 'categorie_admin' allows to know its use. rd / intersection / junction_pn / roundabout. The total length of the network coming together as the sum of the cumulf-cumuld of the rd and giratoire. Field determination rule: axis the wording of the route is in the form of Dxx (e.g. D23) For roads with name extensions (letter after the number of the RD), this extension is added afterwards with a minus (indent of 6) in separator (e.g.: D23-C). For roundabouts an extension 'GIRxxx' is added next with an underscore (tiret of 8) as a separator. ex D72-A_GIR_02_0262. PR of the entry of the roundabout on 2 characters with 0 in prefix to complete 4-character abscissa of the roundabout entry with 0 prefixes to complete Field determination rule: axis_cd01 Axes of the Departmental Routes of Ain (e.g. 01 D0117A). Rules for naming roundabouts (in the process of being entered): E.g.: GIR0117A_09_0611 GIR route type prefix RD number on 4 characters with 0 in prefix to complete Letter from RD with _ if no letter Separator _ PR of the entry of the roundabout on 2 characters with 0 in prefix to complete 4-character abscissa of the roundabout entry with 0 prefixes to complete Intersection management scheme: ![Intersection Management Scheme](https://geodata.ain.fr/apps/external/img/GPR_schema_intersection.png)
