Research of a Problem of Terrorist Attacks in the Metro (Subway, U-Bahn, Underground, MRT, Rapid Transit, Metrorail)

Abstract

This study considers the problem of protecting metros against terrorist attacks. We have collected statistics on all terrorist attacks committed in the metro since 1883, and we have analyzed the efficiency of technical security systems deployed at the metro. The analysis conducted showed that technical systems employed presently in metros cannot prevent bringing explosive devices of a certain type into the metro. Mathematical calculations make it possible to establish the assigned risk of delivering explosive devices of a certain type into metros. The research offers a possible way of increasing the level of security in the metro against the conveyance and use of explosive devices.
