Road plan - Underground ramps

Underground type ramp - An R.T.S connects two Pavement sub-assemblies (S.E.V) from a zero level to a lower level (overhung). The access ramps of the expressways are considered as R.T.S if the slope of the ramp is greater than 4%. An R.T.S can therefore connect two carriageway S.E.V belonging to zero-level road spaces (E.V).The Paris Road Plan: The Paris Road Plan (PVP) is intended for the technical examination of projects on public roads, in accordance with the road regulations in force. Each object in the public space is represented by a symbol referenced in the topographic graphic charter. The original planimetric coordinate system of the PVP is the Lambert I-54 (City of Paris), reprojected in RGF93.CC49 then in RGF93 – Lambert 93 (WKID 2154) in the City information system, then in the international coordinate system WGS84 Web Mercator Auxiliary Sphere (WKID 3857). For this reason, the data presented here cannot be the subject of topographical work. Updates to the Road Plan are now established directly in the legal coordinate system: NGF.IGN69 in altimetry and RGF93.CC49 in planimetry. In accordance with road regulations, all stakeholders in the public domain are required to send their as-built plans to the Road Plans Division (DPV) within a maximum period of 21 working days after the completion of the work. The DPV updates the road plans based on the feedback of this information. The volume of transformations of the public space in recent years does not guarantee the exhaustive updating of the 60 thematic data layers on the entire Parisian territory. As part of a localized project, impacting the road domain (Occupation of the public domain – CITé), the PVP data can be obtained from the Dissemination Office of the Road Plans Division by messaging at the following address: pvp.dvd@paris.fr.
