Quantifying individuals\u27 trade-offs between privacy, liberty and security: The case of rail travel in UK

Public transport systems have been targets in several terrorist attacks, notably in recent years, resulting in tight security measures worldwide. However, individuals\u27 privacy and liberty often conflict with efforts towards safety and security, making it difficult to assess the implications of security measures balanced against the costs (e.g., citizens may be stopped, searched and asked to provide personal identification data to authorities without any particular reason). Henceforth, the authors\u27 research question asks, to what extent would people sacrifice their right to privacy and liberty in exchange for potentially safer and more secure travel? This paper uses a stated choice experiment to quantify individuals\u27 trade-offs between privacy and security within a real-life context, namely rail travel in the UK. Using a nationwide sample, the empirical analysis yields the importance of improvements in the security infrastructure and identifies areas of concern with regard to privacy and liberty controlling for travel related factors. Further, trade-offs across different security measures for rail travel are quantified in terms of individuals\u27 willingness-to-pay extra on top of the average ticket price
