Ensuring that Saclay is less than 30 min. from Paris, Orly, and La Défense and less than one hour from Roissy is a major attraction that will considerably strengthen the credibility of the research cluster. Several plans have been studied to for this purpose.

  • An improvement of existing public transit:
    • Increasing service frequency and improving bus lines (especially line 91.06, the most used)
    • Extending reserved- track public transport rights of way
    • Improving the RER lines
  • The development of new means of transport
    • Development of means of soft traffic (bicycles, electric cars, etc.)
    • Construction of a station in Saclay as part of the Greater Paris Metro system

Through the joint action of the Syndicat des Transports d’Île-de-France, the Région Île-de-France and the Communauté d’Agglomération du Plateau de Saclay, the MobiCAPS bus network has received significant qualitative and quantitative improvements over the past two years.

  • New progress since 30 May 2011 on line 91.06, one of the most used in the network. The STIF has just invested 3.2 million euros to equip the line with 10 articulated buses. In two years, use of this line has increased three-fold.
  • We can also note that there will be a direct link on Saturdays on the Orly - Massy - Saclay sud (Moulon) – Christ – Saint-Quentin-en-Yvelines route and on Sundays Orly – Saclay sud (Moulon).

The automatic metro

The automatic metro project should help link the nine areas identified (including Saclay) as clusters for economic development called on to bring together businesses, institutions, and universities or research institutions. These areas are intended to become clusters, which is to say groupings of businesses and institutions sharing a same area of skills, in close geographic proximity, linked to each other and complementary.

The Société du Grand Paris (SGP), created in June 2010, is responsible for financing the double loop, the "double eight" of the automatic metro, estimated at 21 billion euros, as well as to develop the areas around the stations.

On 28 May 2011, the supervisory board of the SGP voted unanimously to approve the definitive path, which should be translated into a decree from the Council of State in the coming weeks. The SGP, responsible for the design and construction of the Greater Paris Metro, should then be able to start construction by 2013.

The Saclay trains will begin running by 2025!
