Aramis (personal rapid transit)

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.

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.

The proposed system had custom-designed motors, sensors, controls, digital electronics, software and a major installation (the "CET") in southern Paris.

Social concerns made the development of Aramis difficult; the safety of passengers was at risk because of the lack of security in private cars.
