Development of Network-Based Measures and Computational Methods for Evaluating the Redundancy of Transportation Networks

The objectives of this report are twofold: (1) to develop network-based measures for systematically characterizing the redundancy of transportation networks, and (2) to develop computational methods for evaluating the network-based redundancy measures. Travel alternative diversity and network spare capacity are developed as two quantitative measures to capture the considerations of travelers and planners (i.e., the two main decision-making stakeholders in transport systems). They can address two fundamental questions in the pre-disaster transport system evaluation and planning, i.e., “how many effective redundant alternatives are there for travelers in the event of a disruption?” and “how much redundant capacity does the network have?” In the context of a general network resiliency evaluation framework, the proposed measures of network redundancy can be considered as a critical component in assessing network resiliency and also designing a transportation network more resilient against disruptions. Two additional objectives are to collect data from different sources to develop a case study for evaluating the redundancy of a real transportation network and to conduct a case study using the city of Winnipeg, Canada.
