- Ada in the Paris Metro System
-
- The Ada language has been chosen to develop the automatic piloting system
- on the new Paris underground line METEOR. Reliability, security and
- long-term software lifecycle were determining criteria for the choice of
- the language.
-
- Developed on behalf of the Paris Transportation Authority (RATP) by
- GEC-Alsthom for the trains and Matra Transport for the automatic systems,
- the 20-km long METEOR line will link the South-West and North-East Parisian
- suburbs and will be equipped with 18 railway stations. The trains will
- feature the Matra Transport automatic piloting system. This system
- automatically controls the train traffic, regulates train speed, manages
- various alarm devices, and allows traffic of both automatic and non-automatic
- trains on the same line.
-
- The on-ground and embedded system's software is developed on VAX/VMS platform
- with Alsys AdaWorld's cross environment targeting Motorola 68020 processors,
- and Alsys SMART (SMall Ada Run Time).
-
- The METEOR project amounts to 6 billion French francs, not including the
- trains and is scheduled to ensure up to 96 million passenger trips annually
- beginning in 1997.
