Safety of users in road evacuation: RP vs. SP surveys in demand analysis

Abstract

An advancement on demand models for the simulation of a transportation system in emergency conditions is the aim of this work. Advancement is related to demand models specified for the research project SICURO, organized by the Laboratory for Transport Systems Analysis (LAST). Herein we propose specification and calibration of generation and distribution with modal choice models. In comparison with demand models previously presented, a generation model according to a behavioural approach is proposed. Major attention is focused on SP (Stated Preference) surveys, in comparison with the RP (Revealed Preference) surveys previously considered.
