Operational Requirements
Sound Diffuser Prescriptions
Île-de-France Mobilités has drawn up regulations on the sound system of passenger information with the aim of stabilising operators' practices and having a referential on the design of all passenger information distributed to passengers for the various transport areas and vehicles in the Île-de-France region.
The objective, as mentioned above, is to harmonize the practices and sound content deployed. These requirements are fully in line with the ambition sought by the SDIV and its objectives.
Concerning the document itself, it is built with a view to serving as a referential for the design of Passenger Information broadcast via the sound channel, both in stations and stopping points as well as on board.
