At 5.45am on Tuesday 17 January 1995, Kobe, Japan experienced one of its deadliest and costliest earthquakes. Lasting 20 seconds, it registered 7.3 on the Richter scale, paralysing the commercial hub, and leaving death, destruction and chaos. The major infrastructure networks of the region were left in ruins.
It was the colossal impact of this event that has since shaped the study of network vulnerability, and in particular, the study of transportation network reliability. This forms the foundation for a new book by UniSA Emeritus Professor of Transport Planning Michael Taylor.
Prof Taylor is a pioneer in the development of concepts, theory and application of transportation network vulnerability analysis.
In Vulnerability Analysis for Transportation Networks, he presents the most current, complete and integrated account of transport network vulnerability analysis. Considering transport systems performance of degraded transport networks, from system failures, to disaster situations, he seeks to understand the socio-economic and environmental impacts on the affected areas.
“Network failures, whether due to natural or man-made events, are of great significance to communities,” Prof Taylor says.
“The effects of such failures may last for long or short periods of time, depending on the cause, but in either scenario, there is always large social and economic impacts.
“Transportation agencies need well-defined concepts and validated models and tools to test networks for their robustness and resilience to failure at different locations.
“This is an essential and integral part of network design and incident management planning, and indeed planning for emergencies.”
The new book reviews the range of existing approaches to network vulnerability and identifies the application of each approach, illustrating them with case studies from around the world.
It covers the dimensions of time (hours, days, weeks, months and years), spatial coverage (national networks, regional areas, metropolitan and urbanised areas) and modes (road, urban public transport and national railway systems), depicting how frameworks can indicate the most suitable accessibility tools and metrics for a particular application.
Vulnerability Analysis for Transportation Networks is a useful resource for academics and researchers in transportation networks, and for practising professionals involved in the planning and management of transportation networks and services.
