This paper presents basic findings obtained by means of a simulation model for representing an evacuation process from a curved bi-directional Italian road tunnel in the event of a fire. Simulations were carried out by using the STEPS people evacuation model associated with a CFD model simulating the fire. It was found that the evacuation time is primarily influenced by the walking time and to a less extent by the pre-movement time in all scenarios studied. The presence of an alarm system reduced the evacuation time for most the tunnel users, allowing them to reach the tunnel exit in safety.

Abstract
This paper presents basic findings obtained by means of a simulation model for representing an evacuation process from a curved bi-directional Italian road tunnel in the event of a fire. Simulations were carried out by using the STEPS people evacuation model associated with a CFD model simulating the fire. It was found that the evacuation time is primarily influenced by the walking time and to a less extent by the pre-movement time in all scenarios studied. The presence of an alarm system reduced the evacuation time for most the tunnel users, allowing them to reach the tunnel exit in safety.File in questo prodotto:
