Safety Of Users In Road Evacuation:
Modelling And DSS For Pedestrian Outflow

Abstract
This paper concerns the simulation of pedestrian outflow related to the
evacuation of a building. In this paper, after a literature review concerning
commercial software suited for the simulation of evacuation, a simulation tool is
proposed and a comparison between results obtained from simulations and data
recorded from an experimentation on a test site is also presented.
1 Introduction
In those cases where a forthcoming disaster can be notified in advance, only
evacuation represents a chance. During the time interval between notification
and effects of the disaster a preventive evacuation can be executed, so a
preventive planning of the activities to be executed in emergency conditions is
fundamental for an efficient evacuation and to reduce clearance time. For this
reason, evacuation calculations are an important part of performance-based
analyses in order to assess the level of life safety provided in buildings.
In the last years a variety of commercial, academic and governmental tools
were produced to support efficient evacuation planning. The availability of tools
and the advent of (relatively) low-cost, high-performance computing platforms
encourage public agencies to consider analytical methods to improve their
evacuation planning or operational practices.
The tools can be classified as regards the classes of adopted models for
transport simulation. They influence the computational complexity of tools and,
in general, the tools’ capability to facilitate decision-making ranging from realtime
to planning exercises.
On the other hand there is also, in certain circumstances, a need for simple
tools able to quantify, in terms of evacuation time, the effectiveness of an
evacuation plan.
