EPA Paris-Saclay - The digital mobility pass in Paris-Saclay

Smart parking management embodies the ambition of the Paris-Saclay Public Development Establishment (EPA Paris-Saclay) to create a sustainable and smart territory. In 2018, the EPA Paris-Saclay is positioned as one of the drivers of the deployment of the first shared and innovative services, through the implementation of a local MaaS platform in partnership with Mobility by Colas.

The Park'in Saclay platform makes it possible to transform static parking into a lever for urban development through modularity by operating three main levers:

  • Limit the impact and place of the car in the city
    • Park'in Saclay makes visible the parking spaces available in construction and multiplies their number thanks to the proliferation of uses.
  • Optimise land
    • By pooling unoccupied parking spaces, Park'in Saclay limits the construction of new on-site parking spaces.
  • Encourage multimodal deferral
    • By providing information on alternative mobility to individual vehicles near car parks, Park'in Saclay promotes carbon-free travel. Parking becomes the starting point for other modes of travel.


By 2026, the Paris-Saclay plateau will have nearly 60,000 users. As an attractive competitiveness cluster, the region faces a major challenge of accessibility for the thousands of residents, employees, students and visitors who daily reach their accommodation, school or business.


  • Improve campus accessibility in peak hours and control the modal share of individual vehicles (target 55% by 2030 vs. 70%)
  • Reclaim public space for the benefit of active and shared modes
  • Reduce the amount of land dedicated to individual vehicles in future real estate transactions. Saving for more virtuous investment


Throughout the Paris-Saclay urban campus, sensors detect free parking spaces in shared or public car parks in real time on the Park'in Saclay application allowing users to book their place in advance. The application also includes other services such as shared bikes, car sharing and electric charging. This encourages users of the application to refer to an environmentally friendly mode of travel and thus reduce the carbon impact.


The indicators show an optimized use of shared parking spaces. Since the opening of the Park'in Saclay service on the Paris-Saclay plateau, more than 2,000 user accounts have been created with more than 5,000 reservations in shared car parks.


  • Capitalisation on the territorial services platform (integration of new mobility offers).
  • Extension of the digital pass to new neighbourhoods adjacent to the Paris-Saclay campus.
  • Link between planning and mobility (hub, logistics, carpooling)
