Abstract

In this paper some results obtained in the SICURO research project carried out by the Laboratory for Transport Systems Analysis (LAST) of Mediterranea University of Reggio Calabria (Italy) are presented. Microscopic models able to simulate supply and demand-supply interaction of a road transportation system in emergency conditions are described. A microscopic link model (car-following) is specified and calibrated. Parameters are calibrated from data observed during a real simulation of evacuation executed in the test site of Melito Porto Salvo (Italy). A computer application is performed in order to reproduce the evacuation phases observed. Some indicators for testing the performance of a road transportation network in emergency conditions are defined and estimated. Keywords: evacuation, microscopic approach, link model. 1 Introduction This paper presents some results obtained in the research project entitled SICURO (supported by the Calabria Regional Authority) carried out by the Laboratory for Transport Systems Analysis (LAST) of the Mediterranea University of Reggio Calabria (Italy). The general objective of the project was risk reduction in urban areas in terms of exposure through the definition and the implementation of evacuation procedures. One of the activities concerns the specification and calibration of models able to simulate transport supply and demand-supply interaction when a population has to be evacuated due to a forthcoming disaster. In such a context, where
