Abstract
• By viewing the transportation critical infrastructure (CI) as a system-of-systems (SOS) and using a holistic approach coupled with Systems Engineering (SE) methodologies, it is possible to assess the criticality of a highway network based on disconnects within the network

Objective
• To measure the criticality of the network based cost and risk given disconnects occurring within the network
• Outcomes– Provide city and government officials a SE
methodology to construct a model for understanding the impact of disconnects in the transportation network
– Help in the decision making process• Cost reduction• Risk mitigation

Analysis Process
• Mathematical Model to Approximate Cost– Given
• Disconnect at node 16 during rush hour• Estimated 7.87 deaths and 19.68 injuries• Roughly 100 linear feet of highway demolished
$10,078,833
Cost per death: $1,120,000Cost per accident: $45,500Cost per foot: $3,686
