Abstract
This paper deals with path design for emergency vehicles (ambulances) in
emergency conditions (hurricanes, earthquakes, etc.) to rescue weak users (the
elderly, disabled persons, etc.). The problem of an emergency vehicle that has to
pick up weak users at fixed points of the network and to take them to the refuge
area is schematized with two different approaches: one-to-one and many-to-one.
The first regards the minimization of generalized cost of a path that connects an
origin to a destination (as a shortest-path problem); the second considers the
connection of one origin to many destinations (as a vehicle routing problem).
Starting from a brief review of both these problems, the available tools for
planning evacuation of weak users in emergency condition in the within of oneto-
one and many-to-one are analysed. Finally, on the basis of a real simulation of
evacuation, we provide experimental results obtained by testing the effectiveness
of a commercial tool when little time is available for planning evacuation
operations.
Keywords: evacuation, path design, emergency vehicles, genetic algorithm,
vehicle routing, tools.
1 Introduction
In response to catastrophic events whether natural (floods, hurricanes, wildfires,
etc.) or man-made (nuclear and chemical accidents, terrorist attacks etc.) risk
assessment [1] and evacuation operations has become increasingly topical to
rescue human lives. In particular, two different activities can be distinguished:
