The use of simulation to demonstrate autonomous vehicle safety was an essential complement to physical validation (tests on benches, tracks, and roads) to ensure safe behavior of the vehicle in various situations. The 3SA project aimed to study methods and tools for simulating autonomous driving systems, modeling sensors, providing a scenario library, analyzing simulation results, and creating a methodological reference.

Launched in 2019 for a four-year period, the 3SA (Simulation for the Safety of Systems in Autonomous Vehicles) project was an extension of the SVA project, and it aimed to further the use of digital simulation to demonstrate the safety of autonomous vehicles.
