Abstract
This paper on the calibration of cost functions and simulation is from the proceedings of 14th international Conference on Urban Transport and the Environment in the 21st Century, which was held in Malta in 2008. This paper is one of five papers that focus on the safety of users in road evacuation. In this paper, the authors present advancements in Dynamic Traffic Assignment (DTA) microscopic models that are used for the simulation of supply and demand-supply interaction of a road transportation system in emergency conditions. These microscopic models are related to link and node models specified in the research project SICURO, carried out by the Laboratory for Transport Systems Analysis (LAST) of the Mediterranea University of Reggio Calabria in Italy. The models include microscopic link (car-following) and gap-acceptance (rejection) models for non-signalized intersections; the models are calibrated from data observed during a simulation of an evacuation conducted at Melito Porto Salvo, Italy.
