Trends of Modern Terrorism in the Metro Systems of the World

The issue of anti-terrorist protection of metro systems in recent decades has significantly worsened. This is due to the general growth of the terrorist threat in the world. According to the Global Terrorism Database of the National Consortium for the Study of Terrorism and Responses to Terrorism (START), a number of terrorist attacks have been committed in metro systems of various countries of the world, including Britain, Russia, USA, Japan and France. For effective measures to counteract such attacks, it is necessary to clearly know the trends of modern terrorism, particularly on the basis of systematization and analysis of statistical data on the terrorist attacks committed in the metro systems with the subsequent formation of a matrix of trends, which in this case was carried out by the authors of the article. The main statistical analysis method is the factor analysis. The proposed matrix helps to assess terrorist threats for metro systems and can be used to develop measures to ensure their security. The Matrix of Trends of Modern Terrorism in the Metro Systems’ main trends are identified: frequency of attacks; object of attacks; tool of attacks; method of attacks.
