Abstract

This paper presents an application of a system of models and procedures for signal setting design on a road network in evacuation conditions. The system of models, based on a what-to approach, generates signal setting parameters taking into account users behaviour at path choice level. The application has been executed on a real experimental test site with the objectives of validating the system of models and minimizing evacuation times. Keywords: signal setting design model, application, evacuation conditions. 1 Introduction This work is part of research project SICURO, carried out by the Laboratory for Transport Systems Analysis of Mediterranea University of Reggio Calabria (Italy). The general objective is risk reduction in urban areas in terms of exposure through the definition and implementation of evacuation procedures [1, 2]. The results concern the development of models, procedures and guidelines that support transport planning in evacuation conditions. Specific research lines defined in SICURO concern travel demand [3, 4], planning processes and guidelines [5, 6], paths of emergency vehicles [7, 8], pedestrian outflow from buildings [9], transport supply and demand-supply interaction. As regards the last research line, the specification and calibration of link and node models and an application of a dynamic traffic assignment model are reported in [10] and [11]; they present advancements concerning link and node models calibration through data observed during a real-world evacuation experiment. A selection of decision support systems is compared in [12], testing their response capabilities to help validate procedures in evacuation conditions.
