Study focused on the effectiveness assessment of several different fire protection ventilation strategies applied to both single and double track tunnels of driverless metro lines. The analysis was performed using numerical simulation tools: SES for the 1D simulations, ECART for the 3D simulations and FDS as a CFD tool. In particular a pre - post processor tool (ProSES) for helping in the use of SES was developed by “Politecnico di Milano” for Metropolitana Milanese, while ECART is a 3D Well mixed and Fast running numerical tool developed by “CESI Ricerca”. The fire scenarios investigated varied from a train in fire stopped along the tunnel to one stopped at station, while the value of fire HRRMAX was considered from 5 to 25 MW. Both incidental and criminal type of fire scenarios was considered.

In particular a pre - post processor tool (ProSES) for helping in the use of SES was developed by “Politecnico di Milano” for Metropolitana Milanese, while ECART is a 3D Well mixed and Fast running numerical tool developed by “CESI Ricerca”.
