Operational Requirements
Signage requirements
The signage requirements present all the graphic elements prescribed by Île-de-France-Mobilités in terms of Passenger Information and signage, as well as the principles of construction and application of graphic objects.
Intended for transport and mobility stakeholders in the Île-de-France region, the signage requirements aim to establish a coherent passenger information system for all users of the Île-de-France transport system. They are intended to guide operators in the construction of signage and passenger information elements (choice of font, references to the colour palette, methods of use of pictograms, etc.).
They are based on 5 downloadable resources below:
- A referential "signage requirements for public transport and mobility operators in Île-de-France", presenting all the graphic elements available on the PRIM platform, followed by implementation at bus stops, in tram stations, in metro stations and in train/RER stations (in project);
- A library of graphic objects divided into 13 categories (fashion symbols in Île-de-France, new mobilities and intermodal services, services located in transport spaces, places of interest, traffic information, information services and transport tickets, means of payment, accessibility, safety, hygiene, prohibitions, regulations and directional arrows);
- A folder containing the color charts (CMYK colors for paper application and RGB colors for digital application);
- A file containing the policies of the Île-de-France Mobilités signage system: IDF Voyageur (whose use is preferred in constrained spaces) and Grand Paris (whose use is privileged in dense spaces);
- A folder containing tools to help design bus line indices.
- NEW IN 2025 : In addition, Ile-de-France Mobilités provides mobility operators with a Guide to the Use and Adaptation of Static Supports. This is accompanied by libraries of templates and tools allowing users to have ready-to-use elements (posters, commercial information, knowing how to travel, buses,...). You will find them in the " Guide to Static Media" section of this page.
