Risk In Anthropic Environments: Methodologies
For Risk Evaluation And Exposition Reduction
Author(s)
F. Russo & A. Vitetta
Abstract
The simulation of an anthropic environments system in emergency conditions
requires the study of two strictly connected models: risk analysis and evacuation
design. To reduce the exposure component of the risk, evacuation measures have
to be implemented. When an event happens in a system or is forecasted in the
short term, the evacuation measures have to be applied and in some cases have to
be designed in real time. This paper is developed with the following main
objectives: the formalization of the risk problem; the definition of the probability
(or the frequency) that the event occurs, the vulnerability and the exposition with
particular reference to a transportation system; the specification of evacuation
measures for the reduction of exposition and risk.
Keywords: risk analysis, evacuation, simulation, network design.
1 Introduction
This paper proposes methods for the simulation and design of a transportation
system under conditions of safety and/or security. Safety and security problems
are connected with events that generate emergency conditions, such as the 9/11
attack, Atocha station, and the Asian tsunami. Methods for planning a
transportation system in an urban area when exogenous events affecting the
system occur and/or in emergency conditions, have received little attention from
transportation and risk researchers as well as research institutions and journals.
Emergency conditions related to safety and/or security problems in a
transportation system can be activated by exogenous events (power failure,
radiation leak, etc.) or by endogenous events to the transportation system
(dangerous emissions, etc.). The dangers for the population could be immediate
(such as the emission or the discharge of hazardous goods from a truck,
