Man-made threats determination and ranking for the main parts of the subway stations

Congregation of passengers is one of the main reasons that makes the subway stations as high risk places which are often exposed to various man-made risks and threats. Determining and ranking the future threats in each area of the subways are the preliminary acts in crisis management according to the passive defense concept. This research investigates the ranking of those man-made intentional threats which likely exist in the subway stations and public places. A descriptive method (content analysis) has been taken in this research along with utilizing the library studies as well as a questionnaire to gather the specific information. The major threats of the subway stations were extracted and the rank of the threats was determined to achieve the most significant ones. The reliability of the questionnaire was validated by Cronbach’s Alpha test. The findings showed that the terrorist threat such as bomb-planting is the main threat in the subways. The other eight threats in the subways were ranked based on four indices of “damage severity”, “enemy capability”, “targeting attractiveness” and “threat precedence in the main stations of the subways’’.
