Securing Public Transportation Systems

Book excerpt: Florian Brauner addresses the risk reduction effects of security measures (SecMe) as well as economic and social effects using terrorist threats in public transportation as use case. SecMe increase the level of security but cause interferences and restrictions for customers (e.g. privacy). This study identifies the interferences and analyzes the acceptance with an empirical survey of customers. A composite indicator for the acceptance of different SecMe is developed and integrated into a risk management framework for multi-criteria decision analysis achieving the right balance of risk reduction, costs, and social acceptance.
