Safety of users in road evacuation: simulation of a user refuge area

摘要

In this paper some results obtained in the SICURO research project are discussed, especially with regard to users who evacuate with motorized modes due to a forthcoming disaster and their movement to an area of refuge. Evacuation produces temporary over-saturation of some supply components and creation/dispersion of queues, in particular upcoming and moving in the refuge area. To analyse this event two problems must be explored: access to the refuge area and the internal organization. The problems are studied by using deterministic and stochastic queuing theory. Calibration data were obtained from a real experiment executed in the urban area of Melito Porto Salvo in the province of Reggio Calabria (Italy). Finally a computer application was carried out to reproduce all the evacuation phases observed in the experimental test site of Melito Porto Salvo.
