Transport resilience has 10 dimensions, says Pamela Murray-Tuite. What are these 10 dimensions and how can they help us understand transport network resilience? And what about Godschalk?
Essentially, risk management is all about mitigation, whereas adaptation lays the groundwork for resilience. Risk management is only about preparedness, response, and recovery. By adding adaptation to those three we also add resilience.
Is it possible to devise a simple framework for assessing the resilience of the transport infrastructure? The answer is Yes, and the New Zealand Transport Agency has done so.
The report, written by the Hyder Consulting Group, dated 2010 and titled Network Resilience and Adaptation, assesses and details in great depth the vulnerability and resilience of the transport infrastructure in the East of England. And it uses me as a reference.
Resilience is related to three overarching concepts: 1) the vulnerability to unpredictable shocks, 2) the resources or wealth available to a system to help it change, and 3) the internal controllability of relationships in a system, i.e. its rigidity or flexibility.
