As we have seen an investment in Paris Saclay is part of the Greater Paris project. As mentioned in the
Article 20 of “loi relative au Grand Paris”, the government has created a state-owned company
“Etablissement public” named Paris-Saclay(144)
According to the article 21, Paris-Saclay will have to help to the development of higher education and
also to create a R&D cluster(145). Indeed in this area are already present important universities, and
companies:

The challenge for the region would be to attract more companies and universities in this area, in order
to create a French Silicon Valley. By gathering the different R&D centers, with a high proximity to
companies with high added value, Paris-Saclay should become one of the most advanced R&D areas
in the world. This new area will strongly impact the economic growth of the region because of the
common researches of companies and universities.
Regarding the R&D and IT context, the Greater Paris will also be impacted by the creation of its new
automatic public transport line. Indeed, it is interesting to analyze what are the components needed, as
such a project to see a development of IT components in the region.
Automatic transports use efficient new technologies of localization. Nowadays the systems used in
automatic line (line 14 of the Paris’ tube for example) have to be cheap and efficient enough to
respond to the security norms(147).
These technologies are called “primary localization”. In Paris, the line 14 is equipped by a primary
localization system named “Météor”. Every 720 milliseconds, the train communicate its localization,
which permits to operation center to check its localization and its speed(148).
Others technologies are also used in an automatic line, in order to control the doors opening. Indeed
regarding this issue, an optical system is used.. The principle is to equip the platform with a luminous
receiving, and we place a laser on the train. When the train is positioned at the exact place, it sends a
signal to the platform and opens the doors(149).
Many others technologies are used in an automatic tube line, such as inductive loops, radio beacons,
infrared barriers, video analyze, or telemetry.
New technologies will mainly impact the environment of the Greater Paris. They are nowadays one of
the major factors to build a functioning urban area, to connect the different parts of a city. As we have
seen, an automatic public transport system uses complex technological systems in order to increase the
public transport system efficiency in term of security and convenience for the users. This is why the
simple creation of an automatic tube around Paris can be seen as a major improvement of the region
regarding the new technologies.
