As part of the Equisens project (equipment and facilities for the sensory impaired), RATP is bringing its public transport facilities into line with the 2005-102 law and the Île-de-France Mobilités (formerly STIF) accessibility master plan. To this end, RATP is deploying specific design measures in its RER and Métro stations, adapted to the needs of the sensory and cognitively impaired.

RATP commissioned Patrick Jouin to develop a new range of handrails (single, double and illuminated).

The agency studied and developed a standard range of components adapted to the needs of all passengers, including the sensory and cognitively impaired, while taking into account technical (operation and maintenance) and economic (overall investment and operating costs) constraints.

Particular attention was paid to the product's stylistic ambition and identity, in keeping with the heritage quality of the spaces and the desire for standardization in the design of Metro and RER stations.
