An Approach To Define Pedestrian Escape Routes
In Evacuation

Abstract
This paper considers a method for the definition of pedestrian escape routes by
means of the simulation of pedestrian outflow. Feasible solutions are generated
and compared in terms of evacuation time. In the proposed method an aggregate
model for the estimation of evacuation time of a building is adopted. Such a
method can be easily implemented and can be used to give a first evaluation of
evacuation procedures without performing evacuation drills and can be used to
give a fast response in identifying critical points on the network. To check the
capabilities of the models used within the proposed approach, results obtained
from simulations are compared with data recorded from an experiment on a test
site conducted in a primary school located in an Italian town; an application
consisting of designing escape routes for a school is also presented.
Keywords: evacuation, path search, pedestrian.
1 Introduction
An evacuation can be defined as a general mobilization of people (and/or goods)
due to the occurrence of a calamitous event. Its main objective is to reduce the
number of people (and/or goods) present in the area where the event strikes [1].
Evacuation drills are mainly performed for people to practice leaving the
interested area; these tests can also be used for getting information concerning
the behavior of the people in order to build a set of mathematical models able to
reproduce the evacuation. These models can constitute a Decision Support
System (DSS) to be used for planning emergencies [2].
Simulation models, used to perform quantitative analysis on the operational
conditions of a transportation system in emergency circumstances, differ
depending on the hypotheses made on the representation of the flow
Keywords
