Road sections of the RVA supports real-time road traffic data (FCD) collected before 28.3.2023

This data layer is a selection of sections of the Rennes Métropole (RVA) track and address repository. These sections are linked to the “real-time traffic” data stream distributed by Autoroute Traffic in order to generate a Traficolor. A public contract regulates the provision of this flow and authorises Rennes Métropole to distribute it under ODbL (Open Database License). The FCD data to be used with this repository cover the period from 29/01/2020 to 27/03/2023. These archived FCD data can be disseminated externally on request at sig@rennesmetropole.fr (depending on the load plan, the delivery times may be long). For FCD data dated and after 28/03/2023, the graph to be used is shown below: https://public.sig.rennesmetropole.fr/geonetwork/srv/fre/catalog.search#/metadata/f21e3e8a-4c4a-4a4c-9c38-80c7f121558a Note that the repository used by Autoroute Traffic and the RVA are different. In the Autoroute Trafic reference, certain lanes are represented by 2 separate sections corresponding to each roadway (one-way traffic). In the RVA, the same routes are represented by only one line (circulation in both directions). As a result, some RVA sections have been duplicated to represent the traffic direction of each roadway. The sections concerned are those for which there is a suffix “_D” or “_G” with the identifier of the RVA section. Each section corresponds to a rolling roadway. It is oriented according to the direction of traffic which is unique for all sections. For the sake of readability, we encourage users to shift the duplicate sections to make the Traficolor more visible and to better restore the principle of the 2 roadways. Among the attributes: \- id_troncon = primary key to be used to attach FCD data (see above the duplication principle for suffixed sections “_D” or “_G”)
