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

CIP Transportation

• Rise in Transportation Complexity

Complexity

• Intermodal

• Destinations

• Departures

Components

• Highways

• Airports

• Rail


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

• Model– Highway Network


Analysis Process

• Mathematical Model to Approximate Costs

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


Research Significance

• Contribution: This dissertation provides officials a decision-making methodology and tool for resource allocation and risk mitigation– Metrics that measure the performance of the network

given disconnects occurring– Ranking of K Links affecting the network the most
