Paper presented at TRB2005, the Transportation Research Board Annual Meeting 2005, Washington DC, USA, 9-13 January 2005
A reliable transportation network represents a net benefit to society, and conversely, a vulnerable network represents a net cost to society. Hence, vulnerability ought to be an important parameter for decision-support in cost-benefit analyses, by seeking to establish a link between the terms reliability and vulnerability vis-à-vis costs and benefits. A multi-criteria analysis approach is suggested as an appropriate methodology for analyzing the monetary and non-monetary effects of vulnerability.
Looking beyond the science of vulnerability assessments, this paper discusses some of the network attributes that influence the vulnerability of transportation networks, influences that can be described as structure-related, nature-related or traffic-related attributes. The influences of the individual attributes are then examined as possible candidates for measuring of the vulnerability of the transportation network.
