RATP – New Parisian bus network

Interactive map for passengers

In short

As Ile-de-France Mobilités and RATP prepared to change a significant part of the Parisian bus lines in April 2019 and a communications project was being prepared, RATP contacted User Studio to design a tool dedicated to helping passengers understand the forthcoming changes.

  • 15 preliminary interviews on the fly


Mobility uses are changing, mobility policies are evolving, cities and their neighbourhoods are undergoing change, even more so in Paris than elsewhere. In this context, the challenge of producing quality Passenger Information is essential for an urban mobility brand such as RATP, which is involved every day in dealing with a formidable flow of passengers. During a change as significant as the reorganisation of the bus routes, the expectations and demands of passengers are all the more important given that digital methods of communication and simulation have been perfected in recent years. A nice digital service design topic.

Our involvment

Our work consisted of analysing the potential concerns of users affected by the change within a very short period of time and proposing a detailed and effective solution in the form of information and a simulation tool. We also used the services of our web development partner and monitored the development of the tool.
