Single Points of Failure Analysis of the Strategic Transport Network

Tender description

A question which has arisen during the course of the Review is that of whether there are “single points of failure” in our strategic transport networks. This arose particularly in the South West in the winter of 2013-14, where the region was at times perceived to be at threat of being “cut-off” from extreme weather causing significant and simultaneous flooding to major road and rail routes. A rigorous approach is needed to determine the points/routes which represent potential single points of failure on the strategic transport network, and the consequences of their failure. The strategic transport network in the context of such a study can be deemed to consist of the Strategic Road Network, the Trunk Road Network and the UK rail network. It should also consider those routes that serve wider economic needs, e.g. key energy supply routes, or mainline commuter routes.
