Aramis (personal rapid transit)

The Aramis was an experimental personal rapid transit (PRT) system developed in France for deployment in the Paris area. Aramis included the unique feature of non-mechanical platooning that allowed the small cars to run as virtual trains in areas of higher transit density. This would allow the system to maintain high throughput in busy areas, with the trains breaking up into individual cars and going their separate ways as they approached their destination. In spite of considerable development, the platooning system was never made to work properly, and the cars tended to bump and jar in testing. The project was eventually shut down in November 1987, its place taken by the conventional Véhicule Automatique Léger system developed through the same period.

Phase 0 of Aramis began in 1969. During Phase 0, the patent was processed, a test site was determined, and the Aramis development committee was created. Phase 1 started in 1974. During Phase 1, more test sites were researched, variable-reluctance motor was developed and Aramis' competition was eliminated. Phase 2a began in 1977. During Phase 2a, Aramis was simplified for economic reasons. Phase 3A started in 1978, and during phase 3A tests of the system's main components were run, and more site analyses took place at test locations. Phase 3B was the final phase for Aramis; it started in 1982. During the report for phase 3B, Aramis looked like it was in good shape; however, at the end of phase 3B Aramis was abandoned.

Technical development was conducted by "Engins Matra" company, which then became Matra Transport (and later absorbed by Siemens under the same "Siemens Transportation Systems", now a part of Siemens mobility). The project was financed by the French agency DATAR (French: délégation interministérielle à l'aménagement du territoire et à l'attractivité régionale; English: Inter-ministerial Delegation for Territorial Planning and Regional Attractiveness).

The project met with various failures, for both social and technological reasons. In Bruno Latour's book on the subject, Aramis, or the Love of Technology, the author explores the various shortcomings that led to the stillbirth of the project. The original intention for Aramis was to be an ideal urban transportation system based on private cars in constant motion and the elimination of unnecessary transfers. This new form of transportation was intended to be as secure and inexpensive as collective transportation.
