Système D'aide à La Conduite, à L'exploitation Et à La Maintenance
The Système d'aide à la conduite, à l'exploitation et à la maintenance (SACEM) is an embedded, automatic speed train protection system for rapid transit railways. The name means "Driver Assistance, Operation, and Maintenance System". It was developed in France by GEC-Alsthom, Matra (now part of Siemens Mobility) and CSEE (now part of Hitachi Rail STS Hitachi Rail STS SpA (from ''Hitachi Rail Signalling and Transportation Systems'') or Hitachi Rail STS (previously Ansaldo STS) is a transportation company owned by Hitachi with a global presence in the field of railway signalling and integrated t ...) in the 1980s.

Communications-based Train Control
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This makes railway traffic management safer and more efficient. Metros (and other railway systems) are able to reduce headways while maintaining or even improving safety. A CBTC system is a "continuous, automatic train control system utilizing high-resolution train location determination, independent from track circuits; continuous, high-capacity, bidirectional train-to-wayside data communications; and trainborne and wayside processors capable of implementing automatic train protection (ATP) functions, as well as optional automatic train operation (ATO) and automatic train supervision (ATS) functions," as defined in the IEEE 1474 standard.1474.1–1999 – IEEE Standard for Communications-Base ...
