THE DEPENDENCE OF NATIONAL TRANSPORTATION INFRASTRUCTURE ON ELECTRICITY
New Zealand’s infrastructure networks are becoming increasingly interconnected and dependent on each other for normal operation. While typically studied as isolated systems, disruptions can rapidly propagate across networks with widespread effects for both society and the economy. It is the nature and magnitude of these dependencies which are generally not well understood. With interactions between separate networks and a common reliance on electricity supply, the wider transportation sector and electricity distribution networks have been identified as having major potential as contributors to cascading failures. Through a system-of-systems based analysis, this poster presents the dependencies between electricity and passenger transportation networks comprising; airports, ferries, rail, and petroleum distribution across the State Highway (SH) network.
