Abstract:
Transportation research and development covers a multitude of topics regarding all
areas in transportation. Transportation reliability and vulnerability studies are a new
area that has started to draw a lot of attention particularly about its possible
applications to help disaster management practices. But unfortunately transportation
network risk and vulnerability assessment has not received due recognition so far
when formulating preparedness policies in disaster management operations. There are
various types of studies such as environmental impact assessment, cost benefit studies
for transportation infrastructure where a wide variety of features are looked at, but risk
and vulnerability analysis of the transportation network has not yet been considered
with much importance. One major reason for this can be highlighted as the lack of
established terminology and associated means of analysis that can be specifically
adopted for the purpose. And further more it is difficult to draw a firm consensus on
available methods due to various disparities among the concepts proposed.
