  This paper looks at the vulnerability of transportation networks against minor (e.g. demonstrations) and major (e.g. terrorists attacks) incidents by using an attacker-defender model which applies the game theoretic approach proposed by Bell (2000). An example based in London illustrates the use of the model.
The example analysis shows how the critical links can be identified in the network and illustrates the benefits of using mixed route strategies. The chapter further looks at the impact of infrastructure protection on the optimal solution through defender-attacker-defender models. Different scenarios are defined to reflect the degree of visibility of the protection and the solutions show that this will influence the expected benefit significantly.
