SITI (Safety in Tunnel Intelligence): an Italian global project

The aim of this project is the application of ITS technologies with regard to prevention, intervention and restoration of severe accidents in tunnels. The attention was paid to the probability of a traffic accident in a tunnel, the time dependent hazard function rate could have the special form derived by the Weibull three parameters distribution. The queuing theory and stochastic integrals are used for describing the total amount of transports arriving during a time interval of random length. Thus the ITS application in SITI was the optimisation of emergency planning derived by time dependent risk analysis, for fire accidents in all kind of tunnels, without forgetting the paramount importance of the system in which the tunnel is embedded.
